When I receive video frame images, exif information disappears but agisoft also produces point cloud without this information. I want to get a 3d point cloud from two images without camera intrinsic parameters or GCPs, but I could not figure out how to get it. Software such as Agisoft gets scale-free point cloud without this information, but I want to get it with Matlab. How does AgiSoft produce dense point cloud without camera calibration information? Could you help me?
