Abstract
A lidar and a lidar adjustment method are provided. The lidar includes at least one transceiver component. The at least one transceiver component includes an emitting assembly, a beam splitting assembly, and a receiving assembly. The emitting assembly is configured to emit an outgoing light signal. The outgoing light signal is emitted, through the beam splitting assembly, towards a detection region and reflected by a target object to form a reflected light signal. The receiving assembly is configured to receive the reflected light signal after being deflected by the beam splitting assembly.
Claims20
A lidar, comprising at least one transceiver component,
- wherein the at least one transceiver component includes an emitting assembly, a beam splitting assembly, and a receiving assembly;
- wherein the emitting assembly is configured to emit an outgoing light signal, the outgoing light signal being emitted, through the beam splitting assembly, towards a detection region and reflected by a target object to form a reflected light signal;
- and
- wherein the receiving assembly is configured to receive the reflected light signal after being deflected by the beam splitting assembly.
1 more element
A lidar adjustment method, comprising:
- aligning a light exit port of an emitting assembly with a first port of a beam splitting assembly, the emitting assembly being fixed on a base, and the beam splitting assembly and the base forming an integrated structure or being fixedly connected;
- aligning a light input port of a reflector assembly with a second port of the beam splitting assembly, a reflector supporting assembly of the reflector assembly being fixed on top of the beam splitting assembly;
- aligning a light input port of a receiving assembly with a light exit port of the reflector assembly;
- receiving, through the receiving assembly, a reflected light signal, wherein an outgoing light signal from the emitting assembly enters the first port of the beam splitting assembly, exits from a third port of the beam splitting assembly and emits to a detection region where it is reflected by a target object to form a reflected light signal;
- wherein the reflected light signal enters the third port of the beam splitting assembly and exits from the second port of the beam splitting assembly after being deflected by the beam splitting assembly;
- and wherein the reflected light signal is emitted towards the receiving assembly after being reflected by a reflector of the reflector assembly;
- comparing the reflected light signal with a preset light signal threshold;
- in response to the reflected light signal being lower than the preset light signal threshold, adjusting at least one of a position of the reflector, an angle of the reflector, or a position of the receiving assembly;
- in response to the reflected light signal being greater than or equal to the preset light signal threshold, determining a current position of the reflector to be a desired position of the reflector, a current angle of the reflector to be a desired position of the reflector, and a current position of the receiving assembly to be a desired position of the receiving assembly;
- mounting the reflector on the reflector supporting assembly based on the desired position and the desired angle of the reflector;
- and
- connecting the receiving assembly with the reflector assembly based on the desired position of the receiving assembly.
