Problems solved by technology

For example: In the document "ANovelSetupMethod of 3DLIDAR for Negative Obstacle Detection in Field Environment", one 64-line lidar and two 32-line lidars are used to complete the recognition of the environment and concave obstacles on the road ahead. This method greatly reduces the blind spot of the vehicle, and the lidar scan line More detailed, but the 32-line and 64-line lidars used in this method are expensive and cost prohibitive

Abstract

Disclosed in the invention is a single-line laser radar device comprising a radar installation device, a single-line laser radar and a carrier rack. The single-line laser radar is installed on the carrier rack by the radar installation device. The carrier rack with a preset thickness has a flat rectangular shape; at least three single-line laser radars including a first single-line laser radar, a second single-line laser radar, and a third single-line laser radar are distributed uniformly at one side of the carrier rack; and at least one single-line laser radar being a fourth single-line laser radar or a fifth single-line laser radar is distributed at the middle of each of two sides perpendicular to one side with the first single-line laser radar. The installation position and the pitching angle of the radar installation device can be adjusted. When a radar is installed based on the technical scheme, full coverage of the carrier rack in terms of the scanning range can be realized. The provided device is applied to an unmanned vehicle to complete real-time detection on the environment of unmanned driving.

Description

technical field [0001] The invention belongs to the field of radar scanning detection, in particular to a single-line laser radar device. Background technique [0002] Unmanned vehicles rely on the sensors carried in unknown environments to collect and identify environmental data. As a new type of distance measurement method, laser radar has the advantages of fast measurement speed, high data accuracy and strong real-time performance. It can adapt to complex weather conditions such as light, rain and snow, and is widely used in the field of autonomous navigation of mobile robots. . The perception of the road environment by unmanned vehicles based on lidar is the basis for advanced tasks such as local path planning and autonomous navigation; whether information such as obstacles, feasible areas, and road signs can be detected in a timely and accurate manner determines the performance of unmanned vehicles. Whether it can correctly identify the current road environment, wheth...
