Based on surface roughness of target topography as the main research contents, the preprocessing of topographic gray images and extraction algorithm of topographic feature are researched, and the corresponding extraction of topographic feature is done. The basic principle of gray image filter based on noise characteristics and degraded function algorithm is analyzed. The extraction algorithm of topographic surface roughness based on calculation unit of gray image with appropriate dimension is researched, and the corresponding mathematical model is established. By simulation and checking calculation of an image of a certain digital topography example, it is proved that the extraction method of topographic information based on gray images is feasible. It will provide a new research approach for target information recognition and topography risk assessment accurately.
