Multi-combination laser radar device and scanning method thereof

Abstract

The invention relates to a multi-combination laser radar device and a scanning method thereof. The multi-combination laser radar device comprises a base, a radar installation structure, a plurality of laser ranging components, a time calculation unit, an MCU (micro-control unit) main control component and a communication interface, the radar installation structure is arranged above the base, the laser ranging components are arranged on the radar installation structure and comprise multiple groups of laser transmitters and multiple groups of laser receivers, each group of laser transmitters comprise a plurality of transmitting units on the same vertical plane, laser emergence angles respectively transmitted by the transmitting units sequentially deviate predetermined deflection angles along the vertical direction, and each group of laser receivers comprise a plurality of receiving units on the same vertical plane and are respectively used for receiving laser signals transmitted by the corresponding transmitting units. The multi-combination laser radar device is novel in structure and rich in function and can scan three-dimensional information of detected peripheral objects, peripheral environments can be conveniently monitored in real time, and actions of acquired point cloud data are sufficiently played.

Description

technical field [0001] The invention relates to the application field of laser radar technology, in particular to a multi-combined laser radar device and a scanning method thereof for advanced driving assistance systems, unmanned driving systems, mobile robots, and unmanned aircraft for obstacle avoidance and navigation. 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 at the first time, and to identify, detect and control static and dynamic objects. Tracking and other technical processing, so that the driver can detect possible dangers in the fastest time, so as to attract attention and improve safety. Active safety technology. 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 locat...
