Measuring point positioning method based on laser scanning

The invention discloses a measuring point positioning method based on laser scanning, and the method comprises the steps: 1, setting at least two measuring stations, and enabling a measurement point to be arranged in a common intervisibility region of the at least two measuring stations; 2, controlling the measuring stations to rotate at a constant speed, emitting a laser signal for scanning, andacquiring a rotation angle and a reflected laser signal; 3, processing the rotation angle and the reflected laser signal, identifying identities of a measuring point and the measuring stations, extracting central angle values of the measuring point relative to rotating platforms of the measuring stations which scans the measuring point, and obtaining a relative position of the measuring point andthe measuring stations which scans the measuring point; 4, calculating an interior angle value of a triangle formed between the measuring point and the measuring stations which scans the measuring point according to a result o
