PROBLEM TO BE SOLVED: To measure a position of a feature in the periphery of a road.

SOLUTION: An image with the photographed periphery of the road is stored in an image storage part. A three-dimensional point group model storage unit 709 stores a point group indicating three-dimensional coordinates obtained by laser measurement executed simultaneously with the photographing of the image, as a road surface shape model. A model projection part 172 projects the point group onto the image, and an image display part 341 displays the image and the point group superimposed together on a display. A user assigns a pixel on a measuring-objective feature as a measuring image point by an image point input part 342. A vicinity extracting part 171 extracts a point positioned in the vicinity of the measuring image point and superposed with the measuring-objective feature, from the point group. A feature position calculating part 174 outputs the three-dimensional coordinates indicated by the extracted point, as the three-dimensional coordinates of the measuring-objective feature.
