Abstract:
A vessel is a qualitatively complex movable object, which motion can easily predicted when proceeding in unchanged navigation conditions. When navigation conditions become more difficult prediction of vessel requires the implementation of a complex set of actions to assess the position and parameters of the vessel’s motion relative to the limits and directions of the waterway. Lock approaches are characterized by significantly congested conditions and variable dimensions, tortuosity of the waterway, and spatial navigational hazards of complex form, to indicate which floating and land marks are used, organized in complex patterns. Thus, the complexity of navigational and hydrographic conditions has a limiting effect on the navigator’s ability to control the vessel. As navigation conditions become more complex, the navigator changes priorities in controlling the vessel motion, gradually shifting from controlling the course of the vessel, to controlling the vessel’s speed vector, and then to controlling the motion of the stem and stern. Navigating a vessel in difficult navigational and hydrographic conditions requires periodic clarification of navigational information, for which the navigator turns to the navigational chart, which is a visual source of navigational information. Notwithstanding use of modern aids to navigation to display navigation information, such as, for example, an electronic chart navigation and information system (ECDIS), approaches to locks usually present difficulties when taking into account navigation and hydrographic factors, due to the variability of navigation conditions and the static nature of the navigation equipment system waterway. The use of ECDIS, which enables displaying 3D electronic navigation charts (ENCs) to solve the navigator’s tasks enroute lock approaches, is new. The effectiveness of their use in the process of ship handling through locks, which is significant for the navigator, is performed by modern methods in this article.

Abstract:
User navigation in public installations displaying 3D content is mostly supported by mid-air interactions using motion sensors, such as Microsoft Kinect. On the other hand, smartphones have been used as external controllers of large-screen installations or game environments, and they may also be effective in supporting 3D navigations. This paper aims to examine whether a smartphone-based control is a reliable alternative to mid-air interaction for four degrees of freedom (4-DOF) fist-person navigation, and to discover suitable interaction techniques for a smartphone controller. For this purpose, we setup two studies: A comparative study between smartphone-based and Kinect-based navigation, and a gesture elicitation study to collect user preferences and intentions regarding 3D navigation methods using a smartphone. The results of the first study were encouraging, as users with smartphone input performed at least as good as with Kinect and most of them preferred it as a means of control, whilst the second study produced a number of noteworthy results regarding proposed user gestures and their stance towards using a mobile phone for 3D navigation.

Abstract:
This paper introduces a novel protocol for managing low altitude 3D aeronautical chart data to address the unique navigational challenges and collision risks associated with populated urban environments. Based on the Open Geospatial Consortium (OGC) 3D Tiles standard for geospatial data delivery, the proposed extension, called 3D Tiles Nav., uses a navigation-centric packet structure which automatically decomposes the navigable regions of space into hyperlocal navigation cells and encodes environmental surfaces that are potentially visible from each cell. The developed method is sensor agnostic and provides the ability to quickly and conservatively encode visibility directly from a region by enabling an expanded approach to viewshed analysis. In this approach, the navigation cells themselves are used to represent the intrinsic positional uncertainty often needed for navigation. Furthermore, we present in detail this new data format and its unique features as well as a candidate framework illustrating how an Unmanned Traffic Management (UTM) system could support trajectory-based operations and performance-based navigation in the urban canyon. Our results, experiments, and simulations conclude that this data reorganization enables 3D map streaming using less bandwidth and efficient 3D map-matching systems with limited on-board compute, storage, and sensor resources.

Abstract:
Recently, a new breed of mobile virtual reality (dubbed as “EasyVR” in this work), has appeared in the form of conveniently clipping on a non-isolating magnifying lenses on the smartphone, still offering a reasonable level of immersion to using the isolated headset. Furthermore, such a form factor allows the fingers to touch the screen and select objects quite accurately, despite the finger(s) being seen unfocused over the lenses. Many navigation techniques have existed for both casual smartphone 3D applications using the touchscreen and immersive VR environments using the various controllers/sensors. However, no research has focused on the proper navigation interaction technique for a platform like EasyVR which necessitates the use of the touchscreen while holding the display device to the head and looking through the magnifying lenses. To design and propose the most fitting navigation method(s) with EasyVR, we mixed and matched the conventional touchscreen based and headset oriented navigation methods to come up with six viable navigation techniques—more specifically for selecting the travel direction and invoking the movement itself—including the use of head-rotation, on-screen keypads/buttons, one-touch teleport, drag-to-target, and finger gestures. These methods were experimentally compared for their basic usability and the level of immersion in navigating in 3D space with six degrees of freedom. The results provide a valuable guideline for designing/choosing the proper navigation method under different navigational needs of the given VR application.

Abstract:
A user-controlled navigation system is one of the important aspects of human-computer interaction. Finding best path from one location to another and navigating through that path has been a great concern in the geo-virtual navigation. Earlier studies on the geo-virtual navigation systems mainly focus on navigation and visualization, but lack in geo-spatial analysis. Geo-spatial analysis is the domain of geographic information systems (GIS) in which 3D geo-spatial information is used for navigation, geo-visualization, and geo-spatial analysis. The present study deals with wayfinding in the road network of the campus of National Institute of Technology (NIT) Hamirpur, India, in a hilly terrain. It facilitates perform various types of geo-spatial analyses on the road network and virtual travelling in a 3D space.

Abstract:
Autonomous navigation is an important task for unmanned vehicles operating both on the surface and underwater. A sophisticated solution for autonomous non-global navigational satellite system navigation is comparative (terrain reference) navigation. We present a method for fast processing of 3D multibeam sonar data to make depth area comparable with depth areas from bathymetric electronic navigational charts as source maps during comparative navigation. Recording the bottom of a channel, river, or lake with a 3D multibeam sonar data produces a large number of measuring points. A big dataset from 3D multibeam sonar is reduced in steps in almost real time. Usually, the whole data set from the results of a multibeam echo sounder results are processed. In this work, new methodology for processing of 3D multibeam sonar big data is proposed. This new method is based on the stepwise processing of the dataset with 3D models and isoline maps generation. For faster products generation we used the optimum dataset method which has been modified for the purposes of bathymetric data processing. The approach enables detailed examination of the bottom of bodies of water and makes it possible to capture major changes. In addition, the method can detect objects on the bottom, which should be eliminated during the construction of the 3D model. We create and combine partial 3D models based on reduced sets to inspect the bottom of water reservoirs in detail. Analyses were conducted for original and reduced datasets. For both cases, 3D models were generated in variants with and without overlays between them. Tests show, that models generated from reduced dataset are more useful, due to the fact, that there are significant elements of the measured area that become much more visible, and they can be used in comparative navigation. In fragmentary processing of the data, the aspect of present or lack of the overlay between generated models did not relevantly influence the accuracy of its height, however, the time of models generation was shorter for variants without overlay.

COORDENAÇÃO DE APERFEIÇOAMENTO DO PESSOAL DE ENSINO SUPERIOR
A utilização de visualizadores 3D é algo cada vez mais comum em diversos ramos de atividades. O surgimento de novas tecnologias, com o resultante aumento do poder de processamento dos computadores atuais, tornou possível a criação de ambientes virtuais 3D maiores e mais ricos em detalhes. No entanto, a navegação em ambientes 3D, especialmente os ambientes multiescala, ainda é um problema para muitos usuários. O objetivo deste trabalho é propor soluções para alguns problemas de navegação 3D, a fim de melhorar a experiência de uso nesse tipo de aplicação. Nesse sentido, são apresentadas técnicas que permitem ajustar automaticamente a velocidade de navegação, os planos de corte e o ponto de centro de rotação. É proposta também uma solução para a detecção e tratamento de colisão entre a câmera e os modelos da cena, além de uma técnica que visa impedir que os usuários fiquem perdidos quando nenhum objeto da cena é visualizado. Essas soluções são baseadas na construção e manutenção de uma estrutura chamada de cubo de distâncias (cube map, no original em inglês), que fornece informações sobre a localização espacial dos pontos da cena em relação à câmera. Atualmente em desenvolvimento no Tecgraf/PUC-Rio, o SiVIEP (Sistema de Visualização Integrado de Exploração e Produção) é um visualizador voltado para profissionais da área de exploração e produção de petróleo, que serviu para a detecção e entendimento dos problemas mencionados e para a validação das soluções implementadas.
The use of 3D viewers is becoming common in several activities. The appearance of new technologies, with the resulting increase in processing power, made possible the creation of larger and richer 3D virtual environments. However, the navigation in 3D environments, especially the multiscale ones, is still a problem for many users. The goal of this work is to propose solutions to some 3D navigation problems in order to improve the user experience with this kind of application. In this sense, techniques to automatically adjust the navigation speed, the clipping planes and the rotation center are presented. It is also proposed a solution for the detection and treatment of collision between the camera and the scene, and a technique that aims to prevent users from getting lost when no scene object is visualized. These solutions are based on the construction and maintenance of a structure called cube map, which provides information about the spatial location of the scene points relative to the camera. Currently in development at Tecgraf/PUCRio, the SiVIEP (Integrated Visualization System for Exploration and Production) is a viewer aimed at professionals in the area of oil exploration and production that was used to detect and understand the mentioned problems, and also for validating the implemented solutions.

Abstract:
The most common application of hypertext today is found on the World Wide Web, with the numbers of sites and potential users increasing continually. Hypertext systems are characterized by hyperlinks that allow users nonsequential access to the documents contained within them. Because users are not constrained to read through these documents in a linear manner, new problems may arise not found in traditional paper versions. These problems are generally characterized by a sense of being "lost" within a hypertext system. The user may not know exactly where they are or how to get where they want to be. They have lost many of the visual cues that indicate position found in ordinary texts like books. Navigational aids or overview maps have been suggested as a means to help counteract this problem. These navigational aids can take a standard table-of-contents and extend it dynamically or provide a completely new paradigm of browsing. To that extent, many new varieties of maps (including three-dimensional ones) have been developed but not thoroughly studied. As well, it may be theorized that users of differing cognitive abilities may be helped or hindered by such devices. An empirical study was performed to investigate the effect of multidimensional maps. Three different navigational aids were examined which varied the way pages are displayed along one, two or three dimensions. Two hypertext systems were also where one was roughly twice the size of the other. The participants were given a search task twice to examine performance on page revisits. Finally, three cognitive tests were given to view the effects of individual differences. These included a spatial ability, verbal ability and visual memory test. The results indicated that no performance differences existed between the different navigational aids. However, a significant interaction was present between the maps and the type of Web site; smaller Web sites benefited from the 3D navigational aid. It is theorized that an observed effect for hypertext system was due to site complexity as opposed to size. The results from the cognitive ability measures were mixed. People with low verbal ability scores took longer to locate answers. People with high spatial ability scores found more answers and had scores that were less sensitive to the type of navigational aid used. No significant differences were discovered between people of high and low visual memory abilities.

Abstract:
Ziel dieser Arbeit war die 3D-navigierte Transiliosakralverschraubung in einer experimentellen Studie an Plastik- und Spenderbecken sowie in einer prospektiven klinischen Studie mit einer retrospektiven Kontrollgruppe auf die Praktikabilität und proklamierten Vorteile zu überprüfen. Die Ergebnisse der experimentellen Testung unter Idealbedingungen konnten nicht vollständig in der klinischen Anwendung reproduziert werden. Die 3D-gestützte Navigation ermöglicht im Vergleich zur 2D-gestützten Navigation und der konventionellen Bildwandlertechnik nach Matta und Saucedo eine hohe Genauigkeit. Jedoch führt eine Schraubenfehllage häufiger zu einem neurologischen Defizit. Die Strahlenbelastung ähnelt den Verfahren der Kontrollgruppe; darüber hinaus konnten die OP-Zeiten bei der Patientenversorgung unterschritten werden. Die 3D-Navigation bietet besonders aufgrund ihrer hohen Präzision deutliche Vorteile bei der Transiliosakralverschraubung, ist jedoch auch fehleranfällig und kann damit keine allumfas-sende Sicherheit bieten.

Abstract:

The field of research connected to mobile robot navigation is much broader than the scope of this thesis. Hence in this report, the navigation topic is narrowed down to primarily concerning mapping and scan matching techniques that were used to achieve the overall task of navigation nature. Where the work presented within this report is based on an existing robot platform with technique for providing 3D point-clouds, as result of 3D scanning, and functionality for planning for and following a path. In this thesis it is presented how a scan matching algorithm is used for securing the alignment between provided succession point-clouds. Since the computational time of nearest neighbour search is a commonly discussed aspect of scan matching, suggestions about techniques for decreasing the computational time are also presented within this report. With secured alignment, the challenge was within representing provided point-clouds by a map model. Provided point-clouds were of 3D character, thus a mapping technique is presented that provides rough 3D representations of the environment. A problem that arose with a 3D map representation was that given functionality for path planning required a 2D representation. This is addressed by translating the 3D map at a specific height level into a 2D map usable for path planning, where this report suggest a novel traversability analysis approach with the use of a tree structure.

Abstract:
En neuroradiologie interventionnelle, la machine d'angiographie RX est le moyen d'imagerie par excellence pour guider le médecin dans l'accomplissement de son
geste thérapeutique. Cette machine permet l'acquisition d'une image 3D montrant les artères du patient (ou 3DXA). Cependant, le contrôle visuel du déploiement des
outils (guide, cathéter...) est effectué en 2D avec une image temps réel (ou fluoroscopie). Cette thèse a pour ambition de contribuer à l'amélioration des techniqu
es de guidage en proposant des outils permettant une utilisation de l?image 3D durant le traitement.

Les images étant acquises avec la même machine d'angiographie, nous avons consacré une partie de notre travail au développement de méthodes fiables de calibrage de
la chaîne image portée par l'arceau rotatif de la machine. Le but était de comprendre si l'arceau se déformait ou non sous l'influence de son poids.

Tirant parti du fait que les images sont acquises avec la même machine, nous avons ensuite proposé une méthode de recalage 3D2D entre l'image 3DXA et la fluorosc
opie. Cette méthode exploite les capteurs de position du système et incorpore les déformations subies par le système.

Suite à ces travaux, un système permettant la fusion de l'image 3DXA avec la fluoroscopie a été développé en collaboration avec GE Healthcare et évalué au CHU de Nanc
y pour le traitement des anévrismes cérébraux.

Enfin, un nouveau système doté de deux chaînes images (ou système bi-plan) a été installé à Nancy durant notre thèse. Après avoir développé une méthode de détection 2D du g
uide dans les images fluoroscopiques, nous avons initié une première étude de la reconstruction 3D du guide à partir des images bi-plan.

Abstract:
L'étude et la compréhension de l'évolution des villes est un enjeu sociétal important, notamment pour améliorer la qualité de vie dans une ville toujours plus dense. Le numérique et en particulier les modèles 3D de villes peuvent être des éléments de réponse. Leur manipulation est parfois rendue complexe par la prise en compte de leurs dimensions thématique, géométrique et topologique ainsi que de leur structuration hiérarchique
The study and understanding of cities evolution is an important societal issue, particularly for improving the quality of life in an increasingly dense city. Digital technology and in particular 3D city models can be part of the answer. Their manipulation is however sometimes complex due to their thematic, geometric, topological dimensions and hierarchical structure.In this thesis, we focus on the integration of the temporal dimension and in the enrichment with multimedia documents of these 3D models of the city, in an objective of visualization and navigation on the web. Moreover, we take a particular interest in interoperability (based on standards), reusability (with a shared software architecture and open source components) and reproducibility (to make our experiments durable).Our first contribution is a formalization of the temporal dimension of cities for interactive navigation and visualization on the web. For this, we propose a conceptual model of existing standards for the visualization of cities on the web, which we extend with a formalization of the temporal dimension. We also propose a logical model and a technical specification of these proposals.Our second contribution allows the integration of multimedia documents into city models for spatial, temporal and thematic visualization and navigation on the web. We propose a conceptual model for the integration of heterogeneous and multidimensional geospatial data. We then use it for the integration of multimedia documents and 3D city models.Finally, this thesis took place in a multidisciplinary context via the Fab-Pat project of the LabEx IMU, which focuses on cultural heritage sharing and shaping. In this framework, a contribution combining social sciences and computer science has allowed the design of DHAL, a methodology for the comparative analysis of devices for sharing heritage via digital technology. Dans cette thèse, nous nous intéressons à l'intégration de la dimension temporelle et à l'enrichissement avec des documents multimédia de ces modèles 3D de la ville, dans un objectif de visualisation et de navigation sur le web. Nous portons un intérêt particulier à l'intéropérabilité (en s'appuyant sur des standards), à la réutilisabilité (avec une architecture logicielle partagée et des composants open source) et à la reproductibilité (permettant de rendre nos expérimentations pérennes).Notre première contribution est une formalisation de la dimension temporelle des villes pour une navigation et visualisation interactive sur le web. Pour cela, nous proposons un modèle conceptuel des standards existants pour la visualisation de villes sur le web, que nous étendons avec une formalisation de la dimension temporelle. Nous proposons également un modèle logique et une spécification technique de ces propositions.Notre deuxième contribution permet d'intégrer des documents multimédias aux modèles de villes pour une visualisation et une navigation spatiale, temporelle et thématique sur le web. Nous proposons un modèle conceptuel pour l'intégration de données géospatiales hétérogènes et multidimensions. Nous l'utilisons ensuite pour l'intégration de documents multimédias et de modèles 3D de villes.Enfin, cette thèse s'est déroulée dans un contexte pluridisciplinaire via le projet Fab-Pat, du LabEx IMU, qui s'intéresse au partage de la fabrique du patrimoine. Dans ce cadre, une contribution mêlant sciences sociales et informatique a permis de concevoir DHAL, une méthodologie pour l’analyse comparative de dispositifs pour le partage du patrimoine via le numérique

Esta dissertação continua o trabalho realizado anteriormente no âmbito do projecto DETI-Interact, que consiste num sistema interativo baseado num ecrã público instalado na entrada do Departamento de Eletrónica, Telecomunicações e Informática, para o qual foram desenvolvidas v arias aplicações que permitem interação com conte udos 2D e 3D através de um sensor Kinect. O principal objetivo deste trabalho foi o de melhorar esses métodos com os novos gestos disponíveis pela mais recente versão do Kinect SDK. Foram realizadas três experiencias com utilizadores para avaliar a usabilidade os métodos de interação propostos, proporcionando a oportunidade de melhorar os métodos existentes, levando a contribuição de um novo método para manipulação de objectos 3D.

The solution that was considered in this dissertation involved gesture-based interfaces, since they do not require users to carry or use any input device other than their own body. This dissertation continues and extends previous work on DETI-Interact, an interactive public display system located at the lobby of Department of Electronics, Telecommunications and Informatics, to which several applications have been developed allowing interactions with 2D and 3D contents using a Kinect sensor. The main objective of this work was to improve those methods and develop new ones using the new gestures provided by the latest version of the Kinect SDK. Three user studies were conducted to evaluate the usability of our proposed navigation and manipulation methods, leading to this dissertation main contribution of a novel method for the 3D object manipulation.

Full text
Abstract:
Until recently, our focus has been primarily on the development of a low SWAP-C payload for deployment on a UGV that leverages 2D mapping and navigation. Due to these efforts, we are able to autonomously map and navigate very well within flat indoor environments. This report will explore the implementation of 3D mapping and navigation to allow unmanned vehicles to operate on a variety of terrains, both indoor and outdoor. The method we followed uses MOVEit, a motion planning framework. The MOVEit application is typically used in the control of robotic arms or manipulators, but its handling of 3D perception using OctoMaps makes it a promising software for robots in general. The challenges of using MOVEit outside of its intended use case of manipulators are discussed in this report.

Abstract:
Autonomous navigation and unknown environment exploration with an unmanned ground vehicle (UGV) is extremely challenging. This report investigates a mapping and exploration solution utilizing low size, weight, power, and cost payloads. The platform presented here leverages simultaneous localization and mapping to efficiently explore unknown areas by finding navigable routes. The solution utilizes a diverse sensor payload that includes wheel encoders, 3D lidar, and red-green-blue and depth cameras. The main goal of this effort is to leverage path planning and navigation for mapping and exploration with a UGV to produce an accurate 3D map. The solution provided also leverages the Robot Operating System.

Full text
Abstract:
Herein, we explored path planning in 2.5D and 3D for unmanned ground vehicle (UGV) applications. For real-time 2.5D navigation, we investigated generating 2.5D occupancy grids using either elevation or traversability to determine path costs. Compared to elevation, traversability, which used a layered approach generated from surface normals, was more robust for the tested environments. A layered approached was also used for 3D path planning. While it was possible to use the 3D approach in real time, the time required to generate 3D meshes meant that the only way to effectively path plan was to use a preexisting point cloud environment. As a result, we explored generating 3D meshes from a variety of sources, including handheld sensors, UGVs, UAVs, and aerial lidar.

Full text
Abstract:
The power of artificial intelligence (AI) coupled with optimization algorithms can be linked to data-rich digital twin models to perform predictive analysis to make better informed decisions about installation operations and quality of life for the warfighters. In the current research, we developed AI connected lifecycle building information models through the creation of a data informed smart digital twin of one of US Army Corps of Engineers (USACE) buildings as our test case. Digital twin (DT) technology involves creating a virtual representation of a physical entity. Digital twin is created by digitalizing data collected through sensors, powered by machine learning (ML) algorithms, and are continuously learning systems. The exponential advance in digital technologies enables facility spaces to be fully and richly modeled in three dimensions and can be brought together in virtual space. Coupled with advancement in reinforcement learning and computer graphics enables AI agents to learn visual navigation and interaction with objects. We have used Habitat AI 2.0 to train an embodied agent in immersive 3D photorealistic environment. The embodied agent interacts with a 3D environment by receiving RGB, depth and semantically segmented views of the environment and taking navigational actions and interacts with the objects in the 3D space. Instead of training the robots in physical world we are training embodied agents in simulated 3D space. While humans are superior at critical thinking, creativity, and managing people, whereas robots are superior at coping with harsh environments and performing highly repetitive work. Training robots in controlled simulated world is faster and can increase their surveillance, reliability, efficiency, and survivability in physical space.

Burks, Thomas F., Victor Alchanatis, and Warren Dixon. Enhancement of Sensing Technologies for Selective Tree Fruit Identification and Targeting in Robotic Harvesting Systems. United States Department of Agriculture, October 2009. http://dx.doi.org/10.32747/2009.7591739.bard.

Full text
Abstract:
The proposed project aims to enhance tree fruit identification and targeting for robotic harvesting through the selection of appropriate sensor technology, sensor fusion, and visual servo-control approaches. These technologies will be applicable for apple, orange and grapefruit harvest, although specific sensor wavelengths may vary. The primary challenges are fruit occlusion, light variability, peel color variation with maturity, range to target, and computational requirements of image processing algorithms. There are four major development tasks in original three-year proposed study. First, spectral characteristics in the VIS/NIR (0.4-1.0 micron) will be used in conjunction with thermal data to provide accurate and robust detection of fruit in the tree canopy. Hyper-spectral image pairs will be combined to provide automatic stereo matching for accurate 3D position. Secondly, VIS/NIR/FIR (0.4-15.0 micron) spectral sensor technology will be evaluated for potential in-field on-the-tree grading of surface defect, maturity and size for selective fruit harvest. Thirdly, new adaptive Lyapunov-basedHBVS (homography-based visual servo) methods to compensate for camera uncertainty, distortion effects, and provide range to target from a single camera will be developed, simulated, and implemented on a camera testbed to prove concept. HBVS methods coupled with imagespace navigation will be implemented to provide robust target tracking. And finally, harvesting test will be conducted on the developed technologies using the University of Florida harvesting manipulator test bed. During the course of the project it was determined that the second objective was overly ambitious for the project period and effort was directed toward the other objectives. The results reflect the synergistic efforts of the three principals. The USA team has focused on citrus based approaches while the Israeli counterpart has focused on apples. The USA team has improved visual servo control through the use of a statistical-based range estimate and homography. The results have been promising as long as the target is visible. In addition, the USA team has developed improved fruit detection algorithms that are robust under light variation and can localize fruit centers for partially occluded fruit. Additionally, algorithms have been developed to fuse thermal and visible spectrum image prior to segmentation in order to evaluate the potential improvements in fruit detection. Lastly, the USA team has developed a multispectral detection approach which demonstrated fruit detection levels above 90% of non-occluded fruit. The Israel team has focused on image registration and statistical based fruit detection with post-segmentation fusion. The results of all programs have shown significant progress with increased levels of fruit detection over prior art.

Coastal Lidar And Radar Imaging System (CLARIS) mobile terrestrial lidar survey along the Outer Banks, North Carolina in Currituck and Dare counties. Coastal and Hydraulics Laboratory (U.S.), January 2020. http://dx.doi.org/10.21079/11681/39419.

Full text
Abstract:
The Coastal Observation and Analysis Branch (COAB) located at the Field Research Facility (FRF) conducts quarterly surveys and post-storm surveys along up to 60 kilometers of coastline within the vicinity of the FRF to assess, evaluate, and provide updated observations of the morphology of the foreshore and dune system. The surveys are conducted using a mobile terrestrial LiDAR scanner coupled with an Inertial Navigation System (INS). Traditionally the surveys coincide with a low tide, exposing the widest swath of visible sediment to the scanner as well as enough wind-sea swell or texture to induce wave breaking upon the interior sandbars. The wave field is measured with X-Band radar which records a spatial time series of wave direction and speed. Data for the survey region was collected using the VZ-2000's mobile, 3D scanning mode where the scanner continuously rotates the line scan 360 degrees as the vehicle progresses forward. Elevation measurements are acquired on all sides of the vehicle except for the topography directly underneath the vehicle. As the vehicle moves forward, the next rotation will capture the previous position's occluded data area. Laser data is acquired in mobile 3D radar mode with a pulse repetition rate of 300kHz, theta resolution of 0.19 degrees and phi resolution of 0.625 degrees. Horizontal Datum NAD83(2011), Projection North Carolina State Plane (3200) meters; Vertical Datum NAVD88, meters with geoid09 applied.
