Agisoft Metashape (formerly PhotoScan) allows you to automatically create high-quality 3D object models based on digital photos. To reconstruct an object in Metashape, it is enough to upload photos, no additional information is required. The restored textured 3D model can be saved in various formats – OBJ, 3DS, PLY, FBX, VRML, COLLADA, U3D, PDF.
Metashapeis able to process any photos taken with any digital camera, from any angle. The main thing is that each element of the reconstructed object should be visible from at least two shooting positions. If at least one distance between object points or survey positions is entered into the program, Metashape restores the scale of the entire model and allows you to determine the distances between any points of the object and calculate the area and volume of the object or its parts. If you enter the coordinates of at least 3 object points or 3 survey positions into the program, Metashape automatically binds the model to this coordinate system, allows you to calculate the projection of the model on a given surface (orthomosaic), the DEM relative to a given surface (DEM), save the orthomosaic and DEM in different formats and coordinate systems.
How Metashape Works
Generally, the goal of Metashape users is to restore a textured 3D model of an object. This goal is achieved through four processing steps:
1)Determining the positions and parameters of the external and internal orientation of the cameras. At this stage, Metashape finds common points of photos and determines all camera parameters from them: position (up to scale), orientation, internal geometry (focal length, distortion parameters, etc.). The results of this stage are a sparse cloud of common points in 3D model space and data on the position and orientation of the cameras. In Metashape, a sparse point cloud is not used at further stages of processing (except for the mode of building a model based on a sparse point cloud), and serves only for visual assessment of the quality of photo alignment. However, the sparse point cloud can be exported for further use in external programs.
2) Construction of a dense cloud of points. The construction of a dense point cloud is performed by Metashape based on the calculated positions of the cameras and the photographs used. A dense point cloud can be edited and classified before exporting or moving on to the next step in creating a 3D model.
