Abstract
The traditional method of making true digital orthophoto map is orthophoto correction using digital surface model. Tall buildings will be blocked due to the displacement of image points in orthophoto correction. This paper studies the generation method of true digital orthophoto map based on 3D point cloud geometry, and completes the production of true digital orthophoto map through point cloud registration, absolute orientation, equal interval sampling, vertical projection and texture mapping. This paper studies the equal interval sampling method and vertical projection method in this process, which reduces the time of traditional methods in masking detection and repair, it has high automation.
