Abstract:
Photogrammetry is a method of mapping objects on the earth's surface using aerial photographs as a medium. Orthophoto is a product of photogrammetry. Utilization and processing of aerial photo data are increasingly widespread with the support of various adequate software. This study aims to process aerial photo data and determine differences in the quality of orthophotos produced from Agisoft Metashape and APS Menci software. In this study, 714 aerial photo data were taken using the DJI Phantom 3 pro drone, and 9 Ground Control Points were obtained from static measurements using the Comnav T300 Geodetic GPS, processed using the Agisoft Metashape and APS Menci software, starting from Georeferencing, DEM Making, DTM, Editing Semalines, and Orthophoto. The results obtained from this study visually produce orthophotos that have different lighting. APS Menci is brighter than Agisoft Metashape. In addition, there is also a difference in the area of 9.1 Ha from orthophoto where Agisoft Metashape produced 64.61 Ha while APS Menci was 55.51 Ha. The GSD (Ground Sampling Distance) value of Agisoft Metashape is 4.12 cm and APS Menci is 4.2 cm. From the results of the orthophoto semantic quality test obtained from the interpreter it gives a Level 7 score on the NIIRS (National Imagery Interpretability Rating Scale) based on the IRARS (Imagery Resolution Assessment and Reporting Standards) table, where the resulting orthophoto can detect steps on stairs. It is recommended to use the Agisoft Metashape software for better results and speed of use.

Abstract:
Abstract In constructing three-dimensional models, photogrammetry techniques, particularly close-range photogrammetry techniques, are growing and becoming an alternative, specifically for architectural and historical site modeling. Because they are less costly, simpler, and quicker to complete while producing positive results, there is a great number of photogrammetry software. Still, it is difficult to determine which application provides the best measurement results because user expectations vary. It is necessary to conduct geometric precision and visualization analyses to assess the software’s output. For this experiment, 3D models of a building were created using Agisoft Metashape and MicMac. The geometric accuracy calculated by Agisoft Metashape has RMSE values of x=0.025 m, y=0.037 m, and z=0.021 m. RMSE values for the MicMac are x=0.066 m, y=0.129 m, and z=0.118 m. Visually, the Agisoft Metashape-created three-dimensional model offers superior visual results and fewer connection points than the MicMac GUI. On a three-dimensional building model processed with Agisoft Metashape, the generated cloud-to-cloud distance is comparable to the distance between the reference point cloud. Except for the building’s rear, the distance between clouds using the MicMac is nearly identical to that of the reference point cloud.

Abstract. This paper presents a feasibility study on the use of omnidirectional systems for 3D modelling of agricultural crops, aiming a systematic monitoring. Omnidirectional systems with multiple sensors have been widely used in close-range photogrammetry (CRP), which can be a good alternative to provide data for digital agriculture management. The GoPro Fusion dual-camera is the omnidirectional system used in this work. This system is composed of two cameras with fisheye lenses that cover more than 180° each one in back-to-back position. System calibration, camera orientation and 3D reconstruction of an agricultural cultivated area were performed in Agisoft Metashape software. A 360° calibration field based on coded targets (CTs) from Agisoft Metashape software was used to calibrate the omnidirectional system. The 3D reconstruction of an orange orchard was performed using fisheye images taken with GoPro Fusion. The results show the potential of using an omnidirectional system for 3D modelling in agricultural crops, in particular citrus trees. Interior orientation parameters (IOPs) was estimated using Agisoft Metashape target/software with a precision of 9 mm. A 3D reconstruction model of the orange orchard area was obtained with an accuracy of 3.8 cm, which can be considered acceptable for agricultural purposes.

Abstract:
Active development of digital cameras and computer software has made close-range photogrammetry an extremely popular way to solve various engineering tasks, in particular, to control deformations of constructions and mining objects. Automated measurement of tie points enables reviving traditional techniques of deformation measurement through single shot photogrammetric approach (a zero basis, pseudo parallaxes) at a qualitatively new level. The paper deals with the contour mapping equal displacement method adaptation offered by the first author in the 1970s for processing in Agisoft Metashape. It is proposed to create a virtual basis for two single multi-temporal images by adding a matrix of empty pixels to them. This enables processing those as stereo pair, building virtual point clouds and altitude matrices. In order to test the technique, the authors considered the deflection deformation of various objects under lab conditions and shot their photos with a non-metric camera before and after loading. The obtained images were processed in Metashape, and then the above products were created and contours of equal deformations were plotted. It was found out that the accuracy of displacement value estimation with this method exceeds the spatial resolution of the images more than three times. The technology is applicable for objects deformations monitoring shifting mainly in a single plane, in future it is planned to test it in field at studying slope processes

Abstract:
Uncrewed aerial system (UAS) structure from motion (SfM) monitoring strategies for individual trees has rapidly expanded in the early 21st century. It has become common for studies to report accuracies for individual tree heights and DBH, along with stand density metrics. This study evaluates individual tree detection and stand basal area accuracy and precision in five ponderosa pine sites against the range of SfM parameters in the Agisoft Metashape, Pix4DMapper, and OpenDroneMap algorithms. The study is designed to frame UAS-SfM individual tree monitoring accuracy in the context of data processing and storage demands as a function of SfM algorithm parameter levels. Results show that when SfM algorithms are properly tuned, differences between software types are negligible, with Metashape providing a median F-score improvement over OpenDroneMap of 0.02 and PIX4DMapper of 0.06. However, tree extraction performance varied greatly across algorithm parameters, with the greatest extraction rates typically coming from parameters causing increased density in dense point clouds and minimal point cloud filtering. Transferring UAS-SfM forest monitoring into management will require tradeoffs between accuracy and efficiency. Our analysis shows that a one-step reduction in dense point cloud quality saves 77–86% in point cloud processing time without decreasing tree extraction (F-score) or basal area precision using Metashape and PIX4DMapper but the same parameter change for OpenDroneMap caused a ~5% loss in precision. Providing reproducible processing strategies is a vital step in successfully transferring these technologies into usage as management tools.

Abstract:
Abstract. The rapid advancement of drones and autonomous platforms has significantly enhanced the capabilities of aerial data acquisition. Drones, equipped with cameras, are now widely used in fields such as surveying, mapping, agriculture, or infrastructure inspections. The effectiveness of UAV (Unmanned Aerial Vehicle) platforms depends on factors such as data acquisition, software selection, and processing parameters, all of which influence the resulting products like orthomosaics and digital elevation models (DEMs). Both commercial and open-source software can process UAV data, each with its strengths and weaknesses. Commercial software typically offers higher accuracy but comes at a high cost, while open-source solutions provide a free alternative, though they are less intuitive for some users. OpenDroneMap (ODM), open-source software, offers similar functionalities to popular commercial options, enabling the generation of point clouds, DEMs, and mesh models using advanced algorithms like Multi-View Stereo (MVS) and Poisson surface reconstruction. On the other hand, Agisoft Metashape, a commercial software, is known for its user-friendly interface and comprehensive capabilities, making it popular for aerial imagery applications. In this paper, a comparison between ODM and Agisoft Metashape was conducted, focusing on their algorithms and processing performance. The results emphasize differences in camera calibration accuracy and data orientation. The study examined results from datasets acquired under various conditions. The findings revealed that ODM produces comparable results to Agisoft Metashape, the choice between the two depends on user requirements and specific project needs.

Abstract:
Framställning av digitala terrängmodell (Digital Terrain Model, DTM) är en viktig del för projekteringsunderlag vid markrelaterade frågor. Grunden för en DTM är punktmolnet som innehåller grunddata från mätningen. DTM är användbara i många olika områden, kvalitén bestäms beroende på vilken uppdrag som DTM gäller för. UAS-fotogrammetri är en av metoder som tillämpas för att framställa en DTM, det går även att framställa en DTM utifrån punktmoln från Laserdata NH. En DTM är en modell av endast markyta, där data samlas genom mätning av ett visst objekt. Syftet med detta examensarbete som är utfört vid Institutionen för ingenjörsvetenskap vid Högskolan Väst var att jämföra två olika metoder för framställning av ett punktmoln som är till underlag för en DTM. Punktmoln som framställs med egna mätningar från UASfotogrammetri och ett färdigt punktmoln från Laserdata NH. Målet med jämförelsen är att undersöka om det går att ersätta UAS-fotogrammetri med den kostnadseffektiva Laserdata NH i projektet för ett industriområde (Lödöse varvet) i Lilla Edets kommun, samt om det går att ersätta den överlag. Med hjälp av Agisoft Metashape programvaran framställdes det punktmolnet från mätning från UAS av modellen DJI Phantom 4 Advanced, sedan jämfördes den mot det färdiga punktmolnet från Laserdata NH i CloudCompare programmet. Resultatet på denna studie visar att det går att ersätta UAS-fotogrammetri mot Laserdata NH i just denna och andra liknande projekt som har samma syfte och viss bestämd noggrannhet då punktmolnen inte avviker signifikant från varandra. Medan det inte går att ersätta de mot varandra överlag, då UAS-fotogrammetri erhåller högre noggrannhet när det gäller framställning av ett punktmoln jämfört med vad Laserdata NH har för noggrannhet på sina mätningar<br>Generation of Digital Terrain Model (DTM) is an essential part in project planning in questions related to spatial planning. Basis for the DTM is the point cloud which obtains initial data from the measurement. DTM can be used in different areas, accepted quality level is depending on the assignment for which DTM is produced. UAS-photogrammetry is one of the methods which is used for DTM generation, but it is possible to produce DTM from point cloud originated from Laserdata NH. A DTM is a model representing entirely terrain surface, where the data used for its generation gathers from measuring of a certain object. The purpose of this study accomplished at Department of Engineering Science at University West was to compare two different methods for point cloud generation as a basis for DTM. First point cloud generated comes from own measurement with UAS-photogrammetry and second is a point cloud from acquired Laserdata NH. The goal of the comparison is to examine if it is possible to replace UAS-photogrammetry with the cost effective Laserdata NH in the project for the industrial area (Lödöse varvet) in Lilla Edet municipality, and if it is possible to replace it generally. With help of Agisoft Metashape software the point cloud from UAS-measurement with DJI Phantom 4 Advanced was generated and then compared to Laserdata NH point cloud in CloudCompare program. Result of this study is showing that it is possible to replace UAS-photogrammetry with Laserdata NH in this specific and others similar projects which have same purpose and certain decided precision since point clouds are not significantly deviating from each other. While it is not possible to replace them generally, as UAS-photogrammetry obtains higher precision concerning point cloud generation compared to accuracy that Laserdata NH has in its measurements.

Abstract:
Suitable skidding trail layout is important in sustainable forestry system, thus can minimise the damages to trees and economical losses. In a cooperation between Mendel University in Brno and Kasetsart University in Bangkok a potential use of photogrammetry based skidding trail layout was evaluated. Certain plots of teak plantation in Thong Pha Phum were captured with and further processed in Agisoft Metashape software. On obtained orthophoto single trees were distinguished and understory trees for thinning from below were identified on Weighted Voronoi diagram base. On Kernel Density Estimation base a tree density estimation raster output were created. Considering irregular teak spacing a subjective approach for skidding trail layout design was applied, with emphasis to shorten skidding distances and reducing the possible damages to remaining trees and soils.

Abstract:
AbstractIn 2017, the Archaeology Department of the Canton Zurich defined photogrammetry in Agisoft Metashape as a new standard. The years have shown the advantages of the method, especially when documenting complex 3D structures, like skeletons or ruins, on site. While generating 3D models was a well-trodden path, the storage of 3D models needed some exploration. The first challenge was to incorporate 3D data into a pre-existing archive system. The second challenge was to secure both easy access for everyone and long-term storage at the same time. We propose a solution where access and storage are treated as two separate issues. This allows the content to be viewed without technological restrictions (e.g. as 3D PDF or VR application). While independently the same models are stored in a normalised geometry file (e.g. OBJ file) for long term use. Since long-term standards for 3D data have yet to be established, we have decided to provide a temporary backup system by keeping the raw data (photos) together with the processing report for replication purposes. Our solution comes with a lot of redundancy. However, this is still a trial and error approach, one that we would like to work on with fellow 3D enthusiasts.

Abstract:
Digital photogrammetry is a passive contactless, easy, and low-cost 3D scanning technique, that provides effective and powerful tools for 3D realistic reconstruction, as well as precise and high-resolution models based on Structure from Motion (SfM). Photogrammetry leverages data obtained by Unmanned Aerial Vehicles (UAVs), which have reached significant maturity in the sense that they offer a fast, affordable, and effective method for the acquisition of high-resolution geospatial information and image block (nadir and oblique) with high geometric and temporal resolutions. Data are processed by different available commercial or open-source photogrammetric software aiming at 3D reconstruction modelling. Then, the 3D-generated models can be further processed for quantity assessment by applying geometrical measurements. In addition, models through various geovisualization techniques can be used for realistic representations of the physical world. The current research investigates 3D model reconstruction by applying two photogram-metric software, Agisoft Metashape and 3DF Zephyr, in an example of an archaeological site in Greece focusing on the performance of each approach. Moreover, different distance and noise metrics are applied to compare and geometrically assess the 3D dense point clouds, meshes and Digital Surface Models (DSMs). Furthermore, traditional, and modern geovisualization forms of 3D models are discussed towards approaching the 3D models' representation holistically, aiming to provide guidelines to researchers in this field through a comprehensive workflow from data acquisition to manipulation and capabilities combined with other fields such as Computer Vision. Finally, open issues and future research directions are highlighted as a stimulus to further investigations.

Abstract:
In recent years, the production of panoramic images has been boosted by the increasing use of digital photographiccameras and mobile phones. However, for highly demanding applications such as long-range deformation monitoring, theaccuracy and quality control of panoramic images and processes used to obtain accurate 3D models should be properlyassessed. Therefore, prior to being applied in real projects, the quality of the spherical panoramic images generated bythree widely used computer programs (Agisoft Metashape, GigaPan Stitch and PTGui) is evaluated using the same imagesof a photogrammetric laboratory full of control points and an outdoor environment by shooting from several stations. Inaddition to the assessment of the geometrical accuracy, the study also includes important aspects for practical efficiencysuch as workflow, speed of processing, user-friendliness, or exporting products and formats available. The results of thecomparisons show that Agisoft Metashape meets the required geometric specifications with higher quality and has clearadvantages in performance if compared to the other two tested programs.

Asimismo,existen en el mercado programas fotogramétricos libres y licenciados para generar modelos digitales de superficie (MDS),del terreno (MDT) y ortofotomosáicos. En este artículo se utilizan dos programas fotogramétricos para procesar imágenescapturadas con RPAS como son Agisoft Metashape y Recap Photo, utilizando puntos de apoyo y control terrestre. Elestudio se llevó a cabo en Almenara (España) donde se hizo el levantamiento topográfico con RPAS, capturándose 100imágenes digitales, en un área de 0.38 km2. Se utilizaron 6 PA con la finalidad de orientar bien las imágenes digitales enel sistema de coordenadas local y realizar de forma adecuada la georreferenciación de las imágenes obtenidas duranteel vuelo. Para la obtención del MDT se utilizó el software CloudCompare para hacer el filtrado en la nube de puntosobtenidas de ambos softwares. Los resultados muestran una diferencia en altura entre los dos MDT menor a 28 cmtomando como referencia el MDT de la nube de puntos de Agisoft metashape y en cuanto al error en los puntos apoyoRecap Photo presento mayor error.

Abstract:
A elaboração do mapa de danos revela-se indispensável para um projeto adequado de intervenção no patrimônio histórico. Apesar de sua importância, existem diferentes formas consideradas eficazes para sua produção. Nesse sentido, este artigo busca explorar a metodologia Historic Building Information Modelling (HBIM) a partir do desenvolvimento de um modelo e utilização de ortofotos baseadas em nuvem de pontos, para criar um mapa tridimensional com as informações de danos da fachada sudeste do Prédio Centenário/UFRGS. Para isso, foram utilizados os softwares ACCA Edificius® e Agisoft Metashape®. Como resultado, obteve-se o modelo com o registro das informações das manifestações patológicas na fachada sudeste, para o ano de 2023. Ainda, pode-se identificar a eficácia do uso dos softwares para o levantamento, identificação e inserção de informações de manifestações patológicas em edificações históricas.

Abstract:
The first stage of any construction is carrying out excavation works. These works are high-priced and timeconsuming. Mostly, for geodetic control of the works, the surveyors are using total stations and GNSS equipment. Last decade, UAV technology was a breakthrough in the geodetic technologies market. One of the possible applications of UAV is the monitoring of excavation works. In the article, the opportunities and accuracy of UAV data while performing the excavation works were studied. The surveying of earth volume in the middle of construction works was made using DJI Phantom 4 UAV. The data were being processed using two photogrammetric software: Agisoft Metashape and PhotoModeler Premium. For comparison, the surveying also was made using a conventional total station. For each data source, the 3D models were generated. The obtained models were compared with each other in CloudCompare software. The comparison revealed the high accuracy of UAV data that satisfies customer’s requirements. For the case of two software comparing, it is better to process data using PhotoModeler. The PhotoModeler software allows performing in-depth data analysis and blunders searching.

Abstract:
El levantamiento arquitectónico es básico en la intervención del patrimonio. Las nuevas tecnologías ayudan en la elaboración de planimetrías, en particular la fotogrametría, aunque no siempre es posible llevarlas a cabo por la envergadura de los objetos de estudio. En este artículo se exploran las posibilidades que ofrece esta tecnología, en particular el programa de Agisoft Metashape, en el levantamiento arquitectónico de edificios que por sus extensiones dificultan la toma de medidas e información. Para ello, se expone la metodología llevada a cabo en el caso concreto del conjunto militar de Puente del Congosto, conformado por el Castillo de los Dávila y un puente medieval de 120 metros de longitud. Para el primero se ha realizado un modelo tridimensional a partir de un único vuelo dron, y el levantamiento del segundo se ha llevado a cabo a partir de fotografías tomadas con una cámara digital. De este modo se pretende mostrar un ejemplo de cómo llevar a cabo planimetrías precisas a partir de recursos limitados y en poco tiempo. Además, se muestra brevemente el proceso a seguir para realizar un modelado tridimensional para evidenciar su facilidad y las posibilidades que esta tecnología supone.

Abstract:
Orthoses are products considered assistive technology for maintaining or expanding the skills of people with physical disabilities (Pwd), promoting greater social integration. All Pwd's who have sequelae of hemiplegia/hemiparesis need to use an orthosis. Generally, such an artifact has characteristics that interfere negatively during its use. The design of products (orthesis and footwear) separately often meets the functional requirements but has limitations regarding the conditions to facilitate usability and offer attractive aesthetic attributes that can promote a pleasant experience for people with disabilities. Such aspects influence the way people move around and interfere negatively in the physical rehabilitation process. Rapid prototyping can contribute to the development of these products in a personalized way and provide better patient satisfaction. For this, it is necessary to develop a digital model with reliable dimensions and formats based on three-dimensional scanning. The objective of this study was to demonstrate the quality of the digital model through image capture by different instruments and image processing procedures to obtain the three-dimensional model. Three-dimensional scanning was performed in a hemiparetic woman, patient at APAE-Jaú. The procedures performed were Kinect device and Skanect software; tomography scanning, and digital photogrammetry technique using a professional camera and the software Agisoft Metashape. All scans were aimed at the development and production of orthoses. It was noted that the most efficient digital model for the development of a customized orthosis was the tomography procedure. The software for developing the three-dimensional model is free, however, data collection to obtain the image (CT scanner) is expensive.

Abstract:
The goal of this Coastal and Hydraulics Engineering Technical Note (CHETN) is to document initial results to derive topography on the beachface in the northern Outer Banks, North Carolina, utilizing Planet Labs’ SkySat stereo panchromatic imagery processed in Agisoft Metashape. This technical note will provide an initial evaluation into whether Planet Lab’s SkySat imagery is a suitable image source for satellite Structure from Motion (SfM) algorithms as well as whether these data should be explored as a federal beach project monitoring tool. Depending on required accuracy, these data have the potential to aid coastal scientists, managers, and US Army Corps of Engineers (USACE) engineers in understanding the now-state of their coastlines and employ cost-effective adaptive management techniques.

Abstract:
Imagery collected via Unmanned Aerial System (UAS) platforms has become popular in recent years due to improvements in a Digital Single-Lens Reflex (DSLR) camera (centimeter and sub-centimeter), lower operation costs as compared to human piloted aircraft, and the ability to collect data over areas with limited ground access. Many different application (e.g., forestry, agriculture, geology, archaeology) are already using and utilizing the advantages of UAS data. Although, there are numerous UAS image processing workflows, for each application the approach can be different. In this study, we developed a processing workflow of UAS imagery collected in a dense forest (e.g., coniferous/deciduous forest and contiguous wetlands) area allowing users to process large datasets with acceptable mosaicking and georeferencing errors. Imagery was acquired with near-infrared (NIR) and red, green, blue (RGB) cameras with no ground control points. Image quality of two different UAS collection platforms were observed. Agisoft Metashape, a photogrammetric suite, which uses SfM (Structure from Motion) techniques, was used to process the imagery. The results showed that an UAS having a consumer grade Global Navigation Satellite System (GNSS) onboard had better image alignment than an UAS with lower quality GNSS.
