An optical data processing operational unit (108) includes an optical data obtaining part (301) which obtains laser scan data by a laser scanner mounted on a moving body and image data of a photographed image photographed by a camera mounted on the moving body; and a delay time obtaining part (305) which calculates Δt when the point cloud image viewed from the viewpoint at time a specific time T made based on the laser scan data is obtained and the camera photographs with a delay Δt when the camera is ordered to photograph at time T; wherein relationships of exterior orientation elements of the laser scanner and the camera are known, and Δt is calculated in a condition in which difference in overlapping degree of the point cloud image and the photographed image is minimal.",
