Abstract: This application provides a coordinate transformation circuit and method, applied in the field of LiDAR technology. The circuit includes at least one coordinate transformation module, where the coordinate transformation module includes a control module and a data processing module. The control module is connected to an optical detection module, and the data processing module is connected to the control module. The optical detection module is used to obtain the scanning coordinates and detection distance of the detection point during operation. The control module is used to receive an operation trigger signal and the scanning coordinates and detection distance of the detection point sent by the optical detection module. The control module sends the scanning coordinates and detection distance to the data processing module and controls the data processing module to determine the radar coordinates of the detection point.

Abstract: The present disclosure proposes a master control chip of a LiDAR and a LiDAR device. The master control chip of the LiDAR includes an execution control unit, a communication interface, an operation management unit, and a function test unit. The execution control unit is configured to connect a ranging module of the LiDAR and to control the ranging module to operate ranging. The operation management unit connects to the execution control unit and the communication interface respectively, and is configured to communicate with a peripheral device through the communication interface and to drive the execution control unit to operate. The function test unit connects to each unit of the master control chip of the LiDAR, and is configured to test function states of the units of the master control chip and to report corresponding state information.
