Description

technical field

[0001] The invention belongs to the field of laser large-scale length measurement, in particular to a bionic compound eye laser radar system and method. Background technique

[0002] Lidar technology is an active detection technology that can accurately and quickly obtain target three-dimensional space information. Compared with passive imaging systems and microwave imaging systems, it has strong line angle resolution, high measurement accuracy, strong anti-interference ability, and is not affected by light. Due to the advantages of limited conditions and easy lightweight, it is widely used in military, aerospace and civilian fields such as environmental science, laser guidance, automatic driving, and intelligent transportation.

[0003] Lidar can be divided into scanning imaging and area array snapshot imaging according to the basic method of laser coverage. The former includes three types: mechanical, MEMS and OPA, respectively using mechanical scanning op...
