For more accurate results, more photographs would have to be taken. This is not a high number for 3D data map, but at this point, I was more interested in learning the process. In this instance, another Ogham Stone from Burnham House. Possible Use for Community Archaeology Project: Create complete 3D models of artefacts, georeferenced orthophotos, export of texture.Īs with Visual SfM, a number of photographs must be taken completing a 360 degrees of the object to be scanned. Licence:Professional and Standard (commercial) and Educational (non-commercial) I followed several excellent online tutorials in written and video format.
Basic skills in downloading software and installing them onto computer. Skills Needed:Searching for software online. Unlike Visual SfM, it contains a complete program to numerous specific tasks and different types of data, and, as a novice to photogrammetric software, was easily managed, with an efficient workflow system.ĭigital Artefact: Agisoft PhotoScan – Structure from Motion/Photogrammetry Softwareĭigital Tools Used: Digital Camera, Agisoft Agisoft Photoscan is the dominant photogrammetric software on the market, being used by a range of professions, from archaeology, cartographers to creators of virtual worlds and game developers. It performs photogrammetric processing of digital images and generates 3D spatial data.
It’s completely free for existing users.Agisoft PhotoScan (commonly known as PhotoScan) is a professional tool for a photogrammetry pipeline.
Update from PhotoScan to Metashape today. Distributed processing on a HPC cluster helps to speed up all the calculations for massive data sets even further. Metashape is optimised for multi-core CPUs and multi-GPU systems for fast generation of results. The semantic classification feature automatically groups photogrammetric points into Ground, Vegetation, Building, Road, Car and Man-made classes. GPU acceleration support significantly speeds up the processing, while core implementation greatly reduces memory consumption compared to previous versions.Īutomatic multi-class dense point cloud classification.Īgisoft Metashape is enriched with machine learning techniques to solve the crucial task of higher level interpretation of the scanned data. The new depth map based mesh generation method works directly with depth map data, which allows reconstruction of exceptionally detailed geometry. Improved filtering during dense stereo matching helps to reduce noise on the final surface while preserving thin structures within the scene.
Highly detailed mesh generation based on depth maps. On one hand, it can be understood by new-comers in the field of photogrammetry, yet also has a lot to offer to a specialist who can adjust the workflow to numerous specific tasks and different types of data. Metashape is ideal for use in GIS applications, cultural heritage documentation, and visual effects production as well as for indirect measurements of objects of various scales.Īdvanced digital photogrammetry techniques, paired with intuitive computer visualisation results in a smart, automated processing system. Metashape by Agisoft, previously known as Photoscan, is for 3D spatial data generation and photogrammetric processing of digital images.
