PROBLEM TO BE SOLVED: To provide a spatial coordinate measurement system which accurately measures spatial coordinates of a target point from a place somewhat distant from a position measurement point without moving to this point.;SOLUTION: The spatial coordinate measurement system irradiates a measurement object with a laser beam to measure spatial coordinates of the measurement object and includes: a laser pointer 10 which has a function of measuring a position and an inclination to transmit information of the position and information of the inclination; and a spatial coordinate measurement processing unit which stores therein information of the position and information of the inclination measured from different positions, which are transmitted from the laser pointer 10, as measurement information and obtains a point closer to the measurement object from straight lines of the laser beam with which the measurement object has been irradiated twice or more by the laser pointer, to calculate its special coordinates on the basis of the measurement information and determines the spatial coordinates as spatial coordinates of the measurement object.;COPYRIGHT: (C)2015,JPO&INPIT
