Problems solved by technology

[0004] With the development and improvement of unmanned driving technology, the application of lidar in driver assistance systems is becoming more and more extensive. However, the existing laser scanning radars generally have high manufacturing costs, relatively complex structures, and some are large in size and quality. It is not conducive to the application of lidar in the fields of driver assistance systems, unmanned driving systems and mobile robots, and unmanned aircraft obstacle avoidance and navigation

Abstract

The invention discloses a laser radar device comprising a laser radar structure and a rotating structure. The laser radar structure comprises a plurality of laser scanning assemblies. The laser scanning assembly comprises a plurality of lasers mounted on the rotating structure. The laser emitted by each laser has an exit angle with respect to the rotation axis of the rotating structure. The plurality of lasers are regularly distributed around the rotation axis of the rotating structure. The exit angles of the plurality of lasers with respect to the rotation axis are successively increased in gradient. The rotation of the rotating structure rotates the plurality of the lasers to scan a plurality of rotation angle regions. The laser radar device is simple in installation structure, easy to implement, low in cost and convenient for promotion.

Description

technical field [0001] The invention relates to the technical field of laser radar, in particular to a laser radar device. Background technique [0002] Advanced Driver Assistant System (ADAS), referred to as ADAS, is to use various sensors installed on the car to collect environmental data inside and outside the car in the first time, and to identify, detect and track static and dynamic objects. Active safety technology that allows the driver to detect possible dangers in the fastest time to attract attention and improve safety. The sensors used in ADAS mainly include cameras, radars, lasers and ultrasonics, etc., which can detect light, heat, pressure or other variables used to monitor the state of the car. They are usually located in the front and rear bumpers, side mirrors, inside the steering column or windshield of the vehicle. on the glass. [0003] Early ADAS technology was mainly based on passive alarms. When a vehicle detects a potential danger, it will send out ...
