Photogrammetry isn't really about stereoscopy, it's about building a dense point cloud representation based on many images from different angles, then transforming that to a mesh (and often mapping the textures from photos onto it).
You can also do point cloud with lidar from drones, just tends to be more expensive and heavier - https://enterprise.dji.com/news/detail/how-lidar-is-revolutionizing-mapping-and-geospatial-data https://enterprise.dji.com/news/detail/how-lidar-is-revoluti...
- raxxorrax 7y agoIsn't that called stereoscopy? Matching points from different positions and your viewport coordinates lets you extract point coordinates via triangulation? That would net you a heightmap if you manage to match everything present in all images which then can be transformed into a mesh. But sure, just having a good camera is probably a lot cheaper than using a projection of any form. Probably also significantly faster.
