Title:
LASER DETECTION DEVICE AND CONTROL METHOD AND CONTROL DEVICE THEREFOR, AND TERMINAL
Document Type and Number:
WIPO Patent Application WO/2022/226893
Kind Code:
A1
Abstract:
A detection device, a control method and control device for the detection device, a chip, a computer-readable storage medium, and a terminal, applicable to the fields of intelligent driving, autonomous driving, intelligent manufacturing or surveying and mapping. In addition to a laser transceiver module for performing target detection, the detection device (100) is further provided with a reflecting mirror (120) and a synchronous transceiver module for implementing a synchronization function. The reflecting mirror (120) is configured to reflect an emitted light beam from the laser transceiver module to a detection area, and reflect a reflected light beam from the detection area to the laser transceiver module. Further, the synchronous transceiver module detects the light beam passing through the reflecting mirror (120), thereby realizing high-precision rotation speed measurement and rotation angle measurement of the reflecting mirror (120), so as to adjust the rotation speed of the reflecting mirror in a timely fashion. The detection precision of the detection device (100) is improved. Especially, for the detection device (100) having cost sensitivity but requiring high precision, the cost can be greatly reduced on the premise of ensuring performance. Specifically, the detection device (100) may be a laser radar.
