The invention discloses a two-dimension-used laser radar scanning system and method thereof. The system comprises laser distance measurement equipment, a master control circuit board, a transmission device used for driving an optical rotating mirror to rotate, a clearing switch used for initializing a scanning angle, a communication port used for communication between the master control circuit board and data processing equipment, and the data processing equipment used for processing and displaying data information. The laser distance measurement equipment measures distance information of the current direction and then transmits the distance information to the master control circuit board connected with the laser distance measurement equipment. The master control circuit board is simultaneously connected with the clearing switch and the transmission device. The clearing switch transmits the initial scanning angle to the master control circuit board. The master control circuit board transmits control pulses to control uniform rotation of the transmission device and acquires current angle information. The master control circuit board records the real-time distance and angle information and transmits the information to the data processing equipment through the communication port. The data processing equipment processes and displays the current scanning result.
Description
technical field [0001] The invention relates to the field of laser radar scanning, in particular to a two-dimensional laser radar scanning system and method thereof. Background technique [0002] Lidar is widely used in scanning and monitoring the size of target obstacles and the distance between them and other objects, as well as the running speed of target obstacles, such as the size of obstacles on railway tracks, and the distance and relative speed between rails and obstacles. [0003] Taking the mainstream scanning lidar on the market as an example, this paper briefly introduces the working principle of lidar. Scanning lidar includes a laser transmitter, a laser receiver and a gimbal. The laser transmitter emits a beam of laser pulse, which is received by the laser receiver after being reflected by the target object. Laser receivers accurately measure the time between when a light pulse is emitted from the laser and when it is received by the laser. While the speed o...
