Title:
LASER MEASURING SYSTEM, REFLECTION TARGET BODY, AND LASER MEASURING METHOD
Document Type and Number:
WIPO Patent Application WO/2016/136775
Kind Code:
A1
Abstract:
This laser measuring system comprises a laser measuring device, a reflection target body, and a calculating device. The laser measuring device radiates laser light onto the ground, and is capable of measuring the location of a footprint of the laser light by means of the reflected light from the ground. The reflection target body is situated on the ground in a position in which it is possible to receive the laser light, has a shape formed by cutting out a part of a spherical body using a planar surface, and is capable of reflecting the laser light with a higher reflection coefficient than that of the ground. The calculating device calculates horizontal position coordinates of the center of the spherical body, on the basis of sets of three-dimensional position coordinates calculated from at least four reflected light beams estimated to have been radiated from the laser measuring device and reflected by the reflection target body, and is capable of calculating an error, from the difference between the calculated horizontal position coordinates and horizontal position coordinates of the apex of the reflection target body, measured using a separate survey.
