A kind of equipment used to measure the space location precisely belongs to the application field of the laser photoelectricity measure technique. The invention includes an emission base board, a collimation laser device, a beam regulator, a receiving base board, a supporting bracket, a two-dimension photoelectricity sensor and a signal treating device. The collimation laser device and the beam regulator are connected. The beam regulator is installed on the emission base board and makes the laser beam consistent with the normal of the emission base board to form the laser emission device. The receiving base board is connected with the side end of the supporting bracket. On the supporting bracket installs the gearing, on which installs the two-dimension photoelectricity sensor and the signal treating device. The coordinate center motion locus of the two-dimension photoelectricity sensor detecting surface is consistent with the normal of the receiving base board to form the photoelectricity detecting device. The invention uses the space location measure system of laser photoelectricity and four freedoms to realize the precise measure of the space location relation between the remote objects.
