Abstract

The invention relates to the technical field of laser radar, and provides a laser radar. The laser radar includes a laser transmitter, a collimation unit, a reflection unit, a filter cover, a laser receiver and a main control board, wherein the light emitted by the laser transmitter hits the reflection unit after passing through the collimation unit, and the obtained reflection The light beam passes through the filter cover to obtain outgoing light, and the outgoing light hits the reflection unit again after being reflected, and is then received by the laser receiver, and the main control board calculates according to the beam information received by the laser receiver To output the target object information, a shielding cover is arranged between the collimation unit, the reflection unit and the filter cover, so that the light between the collimation unit, the reflection unit and the filter cover propagates in the shielding cover . The laser radar of the present invention can avoid the adverse influence of the echo of the filter cover on the laser radar, accurately judge the information of the target object, and further improve the use safety level of the external equipment.

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...
