Abstract

The invention relates to the technical field of laser radars, and provides a laser radar. The laser radar comprises a laser transmitter, a collimation unit, a reflector element, a filter, a laser receiver and a main control panel, light sent out by the laser transmitter passes through the collimation unit and then shines upon the reflector element, an obtained reflected light beam penetrates through the filter to obtain emergent light, the emergent light is reflected, then shines upon the reflector element and then is received by the laser receiver, the main control panel works out target object information according to light beam information received by the laser receiver, and a shielding case is arranged among the collimation unit, the reflector element and the filter, so that light among the collimation unit, the reflector element and the filter is propagated in the shielding case. According to the laser radar, adverse effects of filter echoes to the laser radar can be avoided, thetarget object information is judged accurately, and then the use safety level of external equipment is raised.

Description

technical field [0001] The invention relates to the technical field of laser radar, in particular to a laser radar capable of eliminating the influence of the echo of a filter cover. Background technique [0002] In the fields of AGV, industrial robots, etc., smart mobile devices need to ensure their own safety and the safety of personnel in the field, so they need to be equipped with safety lidar. The safety laser radar is to detect the position of the target by emitting a laser beam. Its working principle is to emit a detection laser beam to the detected object, and then detect the echo signal reflected by the obstacle and compare the time with the outgoing laser signal. After proper processing, it can be Obtain target information, such as: distance, outline, orientation. [0003] Secure lidar is very important on smart mobile devices to ensure application security. The test results will directly affect the use and safety level of the product, and its accuracy and reliab...
