Abstract
A laser scanner which includes a mobile station calculates a two-dimensional fixed station coordinate system formed at least three fixed stations, calculates coordinates of intersections of at least three circles, which have the fixed stations as their centers and the distances between each of the fixed stations and the mobile station as their radii, at every predetermined angle as each positioning result of the mobile station while horizontally rotating the laser scanner by 360° around a mechanical point, averages each of the positioning results corresponding to 360° and calculates approximate mechanical point coordinates in the fixed station coordinate system.
