The position of a feature near a road is measured. A captured image of the road and its surroundings is stored in an image storage unit. Points specified by three-dimensional coordinates determined by laser measurement made simultaneously with the image capturing are stored as a road surface shape model in the three-dimensional-points model storage unit (709). A model projecting unit (172) projects the points onto the image. An image display unit (341) displays the image and the points superimposed on the image on a display. The user specifies a pixel on the measurement object feature as a measurement image point through an image point input unit (342). A neighbor extracting section (171) extracts points near the measurement image point and on the feature from the whole points.
A feature position calculating section (174) outputs the three-dimensional coordinates representing the extracted point as the three-dimensional coordinates of the feature.
