Lidar, control method of lidar, and addressing circuit

A lidar, comprising:

• a control module, an emitting module, a receiving module, and an addressing circuit, wherein the emitting module comprises a plurality of groups of emitting units, and the receiving module comprises a plurality of groups of detection units, wherein
• the control module is configured to generate an emitting control signal and transmit the emitting control signal to the emitting module;
• and according to an address of a starting group of detection units paired with an activated group of emitting units, generate a corresponding control signal for detection and transmit the control signal for detection to the addressing circuit, wherein the address of the starting group of the detection units is determined based on a result of a calibration process;
• the emitting module is configured to receive the emitting control signal transmitted by the control module, and activate a corresponding group of emitting units to emit a detection beam;
• the addressing circuit is configured to perform a decoding process and a logic operation process regarding the control signal for detection, determine the address of the corresponding starting group of detection units that has been processed by the calibration process, and determine addresses of other groups of detection units to be synchronously activated at the same time with the starting group of the detection units, determine a channel selecting address, and generate a selecting and controlling signal for corresponding channels;
• and
• the receiving module is configured to receive the channel selecting address and controlling signal transmitted by the addressing circuit, and activate a corresponding group of detection units to perform photoelectric signal conversion of an echo beam.
