LiDAR multi-optical-path power automatic balancing system and method

Abstract

The invention discloses a LiDAR multi-optical-path power automatic balancing system which comprises an optical power measuring system, a quick-changing test fixture, a product posture adjusting system, a product communication module, an upper cabinet and a lower cabinet, the system and the modules are all installed in the upper cabinet, an integrated control system is arranged in the lower cabinet, and the integrated control system is in signal communication connection with the system. The balancing method comprises the following steps: loading a four-degree-of-freedom track through a control system; controlling a posture adjusting system to adjust the posture of the product according to the track; controlling the optical power measurement system to measure the power of each optical path, calculating and processing the measurement data, burning the measurement data into the product, re-electrifying the product, executing the motion trail again, measuring the power value of each optical path, and calculating the deviation between the measurement value and the expected value; and if the deviation is within the range, ending, otherwise, repeatedly executing the steps until ending. According to the automatic balance system and method, full automation of LiDAR multi-optical-path power balance can be effectively realized, and the practicability is high.

Description

Technical field [0001] The invention involves a LIDAR multi -light road power automatic balance system and method, which involves the field of Lidar light road design technology. Background technique [0002] In the process of lidar's light road design, the cycle power is a very important parameter for lidar. Its mathematical model is: [0003] [0004] in: For the echo power; For the power; To receive the pores; For the surface reflectance of the object; α For incident angle; For the system transmission rate; For atmospheric transmission rate. [0005] It can be seen that the back wave power is proportional to the transmitting power, which is inversely proportional to the incident angle. Then, the calibration of the transmitting power before the factory and the power balance of the multi -light road are very important. [0006] At present, the LIDAR light road design has the following features from the perspective of detection: the wavelength belongs to the unsight; the ...

Problems solved by technology

[0007] To sum up, in practical applications, it is impossible to directly distinguish the optical path by human eyes, so that the detection method of the traditional hand-held optical power probe is a phenomenon that blind people feel the image or relies too much on experience; The measurement effect of different optical paths and different emission angles is also not good
