Lidar, transceiver alignment method and system therefor

A LiDAR, comprising:

• a LiDAR optical engine, comprising:
• a receiving plate, including a signal acquisition device;
• an emitting plate corresponding to the receiving plate;
• and
• a plurality of channels defined between the emitting plate and the receiving plate for transmitting laser beams, and signal intensity of the plurality of channels being acquired by the signal acquisition device;
• an adjustment frame, the receiving plate and the emitting plate mounted on the adjustment frame, so as to drive the emitting plate or the receiving plate to move and/or rotate along a vertical direction and a horizontal direction;
• a rotary table, the LiDAR optical engine being mounted on the rotary table;
• and
• a controller, communicatively coupled with the rotary table, and drive the LiDAR optical engine to rotate along the direction vertical and the horizontal direction;
• the controller communicatively coupled with the LiDAR optical engine to control the LiDAR optical engine to perform channel selection and acquisition of channel signal intensity, wherein:
• one of the plurality of the channels is selected as a middle channel and another two of the plurality of channels are respectively selected as a first edge channel and a second edge channel;
• wherein the middle channel is a channel corresponding to a laser beam emitted from a reference emission direction of the LiDAR, and the first edge channel and the second edge channel are symmetrically distributed on opposite sides of the middle channel in a vertical plane;
• the receiving plate is defected to adjust signal intensity of the middle channel to a peak value;
• the receiving plate is defected to adjust signal intensity of the first edge channel to a peak value;
• the receiving plate is defected to adjust signal intensity of the second edge channel to a peak value;
• and
• the emitting plate is defected to readjust signal intensity of the middle channel to a peak value;
• the emitting plate is defected to readjust signal intensity of the first edge channel to a peak value;
• and
• the emitting plate is defected to readjust signal intensity of the second edge channel to a peak value.
