The apparatus includes: a ground control point position obtaining part which obtains information of arrangement positions of multiple optical reflection targets; a laser scanner approximate position data obtaining part which obtains an approximate position of a laser scanner; a laser scanning data obtaining part which obtains data of multiple luminescent points; a processing objective point extracting part which extracts multiple luminescent points having luminance exceeding a specific threshold value; and a laser scanner position calculating part which gives data of the arrangement position of the optical reflection target to each of the extracted multiple luminescent points so as to calculate position of the laser scanner.",
