Magistrantūros baigiamojo darbo tikslas yra išanalizuoti 3D lazerines matavimo sistemas, jų panaudojimą geodeziniams darbams ir palyginti su elektroniniu tacheometru. Atliekant tyrimą buvo panaudoti teoriniai bei praktiniai duomenys ir sisteminė analizė. Tyrimo objektas- stacionarus lazerinis skeneris Riegl LMS-Z420i. Pasirinktas prietaisas yra kol kas vienintelis toks Lietuvoje. Modernios technologijos su naujausiais techniniais sprendimais dėl savo produktyvumo gauna vis didesnę reikšmę geodezijoje. Todėl būtina žinoti jų veikimo principus ir panaudojimo galimybes. 3D lazerinės matavimų sist

Many architects is working with AutoCAD system. But it is very time consuming work when it is needed to do such a work like drawing 3D models of walls with openings. This can be solved because of AutoCAD open architecture. Advantages of this would be less of errors in drawings and more time for other work for architects. Created software is able from 2D draft of lines make 3D walls and, if was chossed, openings. The user describes dimensions of wall and / or opening and the program will change selected line by set of planes with the opening inside. There are a few aviable options for user choi

The interest for a detailed and high solution city model has been large within the project” Optical signature analysis” at the department for Sensor Technology in FOI, Linköping.

With the aid of modern sensors it is possible to create models of buildings.

The basicfunctionality is implemented using Matlab. The geometric model consists of floors, wallsand ceilings.

Abstract:
This project aims to make 3D modeling easy through the use of augmented reality. Black and white markers are used to augment the virtual objects. Detection of these is done with help from ARToolKit, developed at University of Washington. The model is represented by voxels, and visualised through the marching cubes algorithm. Two physical tools are available to edit the model; one for adding and one for removing volume. Thus the application is similar to sculpting or drawing in 3D. Thee resulting application is both easy to use and cheap in that it does not require expensive equipment.

Futurist Sculpting is a collection of techniques for representing dynamic motion in a static three-dimensional model. These techniques allow digital artists to use animation as a new modeling tool. The idea of Futurist Sculpting is inspired by the works of the Italian Futurist artists and it aims to achieve the same goal as the one described by Umberto Boccioni, “to find a form that would be like a remembered motion, the product of time but permanent in space.” However, Futurist Sculpting extends Boccioni’s idea to the new medium of 3D animation and modeling, introducing the tec

Abstract:
This thesis project provides a method to simulate the internal mechanical properties of the undeformed human lower limb when an external force is applied. The value of the external force is determined by the deformed magnetic resonance imaging (MRI) images, which is converted into displacement instead. The purpose is to predict the area of the lower limb that is at most risk of wounds. The tissues of the human lower limb that are concerned in this study are: skin, fat, muscle, fascia, tibia bone, fibula bone and bone marrow. MRI images taken of an undeformed lower limb from experimental people

Abstract:
L’imagerie sismique du sous-sol à partir de données terrestres est très difficile à effectuer due à la complexité 3D de la proche surface. Dans cette zone, les ondes sismiques sous forme d’un paquet compact de phases souvent imbriquées sont dominées par des effets élastiques et viscoélastiques, couplés aux effets dus à la surface libre qui génèrent des ondes de surface de grande amplitude et dispersives.L’interaction des ondes sismiques avec une topographie plus ou moins complexe dans un contexte de fortes hétérogénéités de la proche surface induit d’importantes conversions des ondes avec de f

Le défi de cette thèse est de reconstruire la géométrie 3D de la végétation à partir des données de distance et d'intensité fournies par un scanner de type LiDAR. Une méthode de « shape-from-shading » par propagation est développée pour être combinée avec une méthode de fusion de données type filtre de Kalman pour la reconstruction optimale des surfaces foliaires.-Introduction-L'analyse des données LiDAR nous permet de dire que la qualité du nuage de point est variable en fonction de la configuration de la mesure : lorsque le LiDAR mesure le bord d'une surface ou une surface fortement inclinée

Abstract:
The terrorist attacks on New York City on September 11, 2001 heightened awareness about the need to plan for emergency evacuation measures. As a result, three-Dimensional (3D) city and building models have become an important part of GIS analysis. The technology can be used to plan evacuations in complex indoor environments. This thesis had two main objectives. The first goal was to conduct a 3D network analysis of a building for emergency management, which was based on a 3D model of a building in the city of Gävle, Sweden. This 3D model identifies the shortest path from any room to the define

Abstract:
In order for a system to learn a model for object recognition, it must have a lot of positive images to learn from. Because of this, datasets of similar objects are built to train the model. These object datasets used for learning models are best when large, diverse and have annotations. But the process of obtaining the images and creating the annotations often times take a long time, and are costly. We use a method that obtains many images of the same objects in different angles very quickly and then reconstructs those images into a 3D model. We then use the 3D reconstruction of these images

Abstract:
Plumage is a stereoscopic 3D experience showcasing the culmination of a personal exploration and observation of birds: a digitally modeled and rendered, fantastical bird referred to simply as a Phoenix. In many cultures birds are tied to ideas of freedom, power, and the otherworldly. Preconceived notions of a phoenix exist across many cultures as well, but for this project I wanted to create my own interpretation. While working, I drew upon my admiration of birds for their qualities of strength, beauty, and curiosity to infuse into the project. Inspired by the dynamic and detailed works

Abstract:
The goal of this thesis is to gain a deep understanding of inverse problems arising from 2D image and 3D surface reconstruction, and to design effective techniques for solving them. Both computational and theoretical issues are studied and efficient numerical algorithms are proposed. The first part of this thesis is concerned with the recovery of 2D images, e.g., de-noising and de-blurring. We first consider implicit methods that involve solving linear systems at each iteration. An adaptive Huber regularization functional is used to select the most reasonable model and a global convergence r

Abstract:
Meandering rivers provide fresh water and important aquatic ecosystem services, yet at the same time induce flood and erosion hazards. In the face of ongoing development pressure and changing climate, growing concern for meandering rivers has increased the demand to model accurately the flow and predict the sediment transport in a meandering river channel. Calibration and validation of these models based on comparable field-based data, as opposed to laboratory-scale experimental data, may decrease uncertainty and improve understanding of complex flow structures in natural meandering rivers.

Abstract:
This thesis describes the process of creating a 3D environment from the initial concept to the final scene. It discusses relevant research into new technology in the field of real-time rendering, including Physically Based Rendering and a synced normals workflow. It examines how the goals of the project changed over time and how the associated challenges were resolved. Conclusions are drawn about what practices were most successful, and how the development process could be improved.
