I read this in a trade magazine today,
“Esri has just released the Drone2Map for ArcGIS app, which transforms high-resolution drone imagery into ready-to-use aerial data in the GIS platform. Users can bring point-clouds, mosaic datasets, 3D meshes and orthomosaics directly into the platform in near real time without any third-party application. … Simple photographic data obtained from a miniature camera mounted on a drone can be used for point-cloud collection, rather than rely on airborne lidar.”
How does it generate a point-cloud from the photographic data without some sort of laser or other active sensor? The part in bold above.
Is it merely stereo imagery? https://doc.arcgis.com/en/drone2map/process-and-share/processing-options.htm
