Abstract

The invention relates to the technical field of laser detection and discloses a laser radar device. The device includes a rotor. The rotor is therein provided with an emitting cabin and a receiving cabin. An optical lens assembly is mounted on the side wall of the rotor. The optical lens includes an optical emitting lens and an optical receiving lens communicating with the emitting cabin and the receiving cabin respectively. The emitting cabin is therein provided with an emitting assembly and a first relay mirror assembly. The receiving cabin is therein provided with a second relay mirror assembly and a receiving assembly. According to the invention, the emitting cabin and the receiving cabin of the laser radar device fit specific structure of an emitting device and a receiving device in acabin and the arrangement space of the laser can be reduced.

Description

technical field [0001] The invention relates to the technical field of laser detection, and discloses a laser radar device. Background technique [0002] As an important part of the intelligent vehicle environment perception hardware system, Lidar (LIDAR) undertakes important tasks such as roadside detection, obstacle recognition, and real-time localization and mapping (SLAM) in automatic driving. [0003] The LIDAR system consists of a laser emitting system and a receiving system. The laser transmitter system generates and emits light pulses, hits the object and reflects back, and is finally received by the receiver. The receiver accurately measures the travel time of the light pulse from when it is emitted to when it is reflected back. Because light pulses travel at the speed of light, the receiver will always receive the previous reflected pulse before the next one is sent. Given that the speed of light is known, travel time can be converted into a measure of distance....
