GEOGRAPHICAL INFORMATION PROCESSOR

摘要

PURPOSE: To exactly match the position of a camera image with that of a stereoscopic perspective image by setting correspondent point between the camera image picked up on set image pickup conditions and the stereoscopic perspective image plotted from a three-dimensional map data based on set image pickup conditions. CONSTITUTION: The three-dimensional map data base matched with the image pickup conditions is read out and supplied from a three-dimensional map data base storage means 103 to a three-dimensional map plotting means 104 to which the image pickup conditions are inputted. Then, a coordinate including graphics expressing respective geographical objects is transformed and the stereoscopic perspective image corresponding to the camera image to be picked up according to the image pickup conditions is plotted and outputted to a three-dimensional map/camera image correspondent point input means 105. At the three-dimensional map/camera image correspondent point input means 105, the plural correspondent points are given to the respective data of camera image and stereoscopic perspective image superimposed and displayed on a display device on a picture and outputted to a coordinate transformation formula calculating means 106. At the coordinate transformation formula calculating means 6, the formula of coordinate transformation between the data of camera image and stereoscopic perspective image is found and the stereoscopic perspective image is plotted again.
