The phase difference method has high precision, but according to the phase difference measurement distance between the transmitted and received signals, it can only measure the distance value within half a wavelength, so it is necessary to use several lasers with different wavelengths and frequencies to measure the phase difference. So as to find the measured distance

The invention relates to a spatial point three dimension coordinate measuring method based on rotation sector laser angle measurement. The spatial point three dimension coordinate measuring method based on the rotation sector laser angle measurement uses a spatial point three dimension coordinate measuring system. The spatial point three dimension coordinate measuring system is composed of a sector laser emission end, a sector laser receiving end and a task computer, wherein the sector laser emission end comprises a sector laser emitter which can emit sector lasers capable of rotating around the rotation axis of the sector laser emitter, a sliding platform, a rotation platform and an initial reference, the sector laser receiving end is a sector laser receiver, the position of the sector laser emitter is set as a given point, and the position of the sector laser receiver is set as a spatial point to be measured. During the measurement process, the sector laser emitter emits a beam of the sector lasers which can rotate around the rotation axis of the sector laser emitter from different positions around, the sector laser receiver receives the sector lasers, records related data, and transmits the related data to the task computer, spatial position information of the sector laser receiver can be figured out through related formulas, and then the three dimension coordinate of the spatial point to be measured can be obtained. The spatial point three dimension coordinate measuring method based on the rotation sector laser angle measurement has the advantages of being low in system cost, high in measurement accuracy, and convenient in system building, and furthermore is suitable for various measurement places low in measurement real time request and high in measurement accuracy request.
