Abstract

The embodiment of the invention belongs to the field of laser radars and relates to a detection system based on laser radars. The detection system comprises at least one laser radar; the laser radars are used for acquiring point cloud data information in a detected area, and determining the state of the detected area according to the point cloud data information acquired by the laser radars, the state of the detected area indicates whether an object exists or not and / or the state information of the object. According to the detection method based on the laser radars, the defect that the detection capability of a visual sensor in distance and spatial position is limited is overcome, the defect that the detection range of a single-point laser radar is small is overcome, and more state information of the object in the detected area is obtained in the detection process.

Description

technical field [0001] The present invention relates to the technical field of laser radar, in particular to a detection system based on laser radar. Background technique [0002] When detecting the detection area, the usual methods such as visual sensors and ground markers have limited ability to obtain information, and cannot directly and accurately obtain the distance information of the target object in the detected area. [0003] Lidar is a radar system that emits a laser beam to detect the distance of a target. Its working principle is to send a detection signal (detection beam) to the target, compare the received signal (echo) reflected from the target with the transmitted detection signal, and after proper processing, the relevant information of the target can be obtained. Single-point lidar has a small coverage and can only detect targets within a small detection field of view. [0004] The embodiment of the present application obtains three-dimensional point cloud...
