Description

technical field [0001] The invention relates to the technical field of photoelectric detection, in particular to a monitoring device with the functions of an optical camera and a laser radar sensor. Background technique [0002] Lidar is a radar system that emits laser beams to detect characteristic quantities such as the position and speed of targets. Its working principle is to send a detection signal (laser beam) to the target, and then compare the received signal (target echo) reflected from the target with the transmitted signal, and after proper processing, the relevant information of the target can be obtained, such as Target distance, azimuth, height, speed, attitude, and even shape parameters, so as to detect, track and identify aircraft, missiles and other targets. The laser converts electrical pulses into light pulses and sends them out, and the optical receiver converts the light pulses reflected from the target into electrical pulses and sends them to the displ...

Problems solved by technology

[0005] 1. Most laser radars, including laser quantum radars, do not have camera-level resolution and color information acquisition capabilities;

[0006] 2. Most of the existing cameras do not have the ability to acquire high-precision depth information;

[0007] 3. Systems that take both capabilities into account are generally data fusion at the software level, with low precision, slow response speed, complex system structure, poor environmental adaptability, a large amount of software calibration and calibration, and inconvenient use
