The fixed module is in fact a rotating mechanism which can rotate by a fixed angle, either horizontally or in pitch, under the control of a servomotor. The end part of the fixed module is provided with a laser sensing component, and the laser sensing component synchronously rotates along with the fixed module when the fixed module rotates.

After a certain laser sensing component to be detected is mounted on the fixed module, the laser transmitting module transmits laser signals (20 Hz) under the instruction of the display control module, the laser sensing component receives the laser signals, the display control module calculates the detection probability P according to the transmitted laser times and the received laser times, and the calculation formula is as follows: the number of received laser light/the number of emitted laser light is multiplied by 100%. If P is greater than 90%, the fixed module and the laser sensing component to be tested do not need to rotate, and the current initial azimuth angle A is directly recorded 1 . If P is smaller than 90%, the whole fixed module and the laser sensing component to be tested rotate horizontally by 0.3 DEG, and are connectedThe detection probability P is then measured and calculated again until it is greater than 90% for the first time, the current azimuth angle A is recorded 1 .
