PROBLEM TO BE SOLVED: To accurately correct an error of positioning data by a GPS.SOLUTION: An imaging device 1 uploads a reference image (for example, a distance image) based on an output image signal of an image pick-up element IS and original positioning data (x,y,z) obtained by a GPS positioning. A server device SV extracts a plurality of evaluation target images (for example, the distance images) as to an object having a location around positions (x,y,z) from a data base, searches for a similar image of the reference image from an extraction image group and returns position data of the object associated with the similar image to the imaging device 1. A positioning data correction section 33 corrects the original positioning data (x,y,z) on the basis of the received position data, the distance image based on the output image signal of the image pick-up element IS, and photographing direction data indicating a direction of the imaging device 1 to obtain correction positioning data (x,y,z). |
