Photogrammetry
القياس التصويري
Also known as: Structure from Motion, SfM
Photogrammetry reconstructs 3D geometry from overlapping 2D photos by triangulating common features across images. Modern SfM (Structure from Motion) plus MVS (Multi-View Stereo) pipelines like Agisoft Metashape, Pix4D Mapper, OpenDroneMap, and RealityCapture turn 500 drone photos into a dense point cloud, textured mesh, orthomosaic, and DEM in one batch run.…

Photogrammetry reconstructs 3D geometry from overlapping 2D photos by triangulating common features across images. Modern SfM (Structure from Motion) plus MVS (Multi-View Stereo) pipelines like Agisoft Metashape, Pix4D Mapper, OpenDroneMap, and RealityCapture turn 500 drone photos into a dense point cloud, textured mesh, orthomosaic, and DEM in one batch run. Accuracy tracks ground sample distance — 5 cm GSD plus RTK plus ground control points yields 3 cm RMSE in horizontal and 5 cm vertical. FI Tech runs photogrammetry weekly on every active construction project for as-built tracking and quantity verification.
