Problems solved by technology

[0003] As assisted driving and automatic driving manufacturers gradually increase the demand for parameters such as the limit measurement distance and measurement accuracy of the laser radar system, the existing laser radar system usually adopts the following solutions: 1) Using superimposed single-line laser transceiver devices to achieve multi-line However, with the increase of transceiver devices, the height of radar, the difficulty of installation and adjustment, and the difficulty of mass production all increase accordingly; 2) The line laser transceiver system is used to realize multi-line scanning, but the transmitting system and the receiving system are the same Shafts are stacked, making it difficult to lower the radar height

Abstract

The present disclosure relates to the technical field of radar equipment, and in particular, to a laser radar device. The lidar device provided by the present disclosure includes a body and a core; the core is arranged inside the body, and has a transmitting module and a receiving module; the transmitting module and the receiving module are arranged along the same plane, and the transmitting direction of the transmitting module faces the receiving module; Between the transmitting module and the receiving module, a transmitting optical path adjusting component is also arranged; the transmitting optical path adjusting component can change the laser emission direction so that it is no longer directly facing the receiving module, and has the advantages of compact arrangement of internal components and compact overall structure and volume.

Description

technical field [0001] The present disclosure relates to the technical field of radar equipment, and in particular, to a laser radar device. Background technique [0002] LiDAR systems have important civil and military application value in 3D environment measurement and perception. LiDAR systems are developing rapidly for civilian use, especially in the fields of assisted driving and automatic driving. The LiDAR system is used to measure the spatial distance and 3D environment of the surrounding environment of the vehicle. Reconstruction is a prerequisite for realizing high-precision autonomous driving control. [0003] With the gradual increase in the requirements of assisted driving and autonomous driving manufacturers for parameters such as the limit measurement distance and measurement accuracy of the lidar system, the existing lidar systems usually adopt the following solutions: 1) Use superimposed single-line laser transceiver devices to achieve multi-line However, wi...
