A rapidly extraction method of the digital surface model (DSM) based on GPGPU technology is introduced. Using LiDAR and photogrammetry, this paper discusses the different characteristics about extracting the digital surface model. It proves that the extraction method of digital surface model based on CUDA architecture is effective and feasible by making a comparison of using CPU and GPU technology to obtain DSM of a large mountain block.
