<p>PROBLEM TO BE SOLVED: To improve operation efficiency and accuracy in a mapping system for digitizing map information related to a land form, a planimetric feature, etc. from a survey photograph image.SOLUTION: A plane view image generator 20 generates a plane view image composed of a single image as a survey photograph image. A stereoscopic image generator 22 generates a stereoscopic image on the basis of a stereoscopic pair images, as the survey photograph image. A display image switch processing unit 24, in response to a user operation, switches a display image to be displayed on the screen of a display unit 10 between the plane view image and the stereoscopic image. The plane view image generator 20 and the stereoscopic image generator 22 keep the position of a measuring mark point on the screen and the scale and orientation of the survey photograph image when switching the display image.</p> |
