Claim 0:
1. A LiDAR, comprising:
a casing, demarcating an emission chamber and a receiving chamber;
a laser emission device, arranged in the emission chamber and configured to emit a laser beam to a first target region;
a plurality of laser receiving devices, arranged in the receiving chamber, wherein the plurality of laser receiving devices are configured to receive a laser beam reflected from a second target region, and the first target region and the second target region are at least partially overlapped, among the plurality of laser receiving devices, one of the laser receiving devices and an other one of the laser receiving devices are located on opposite sides of the laser emitting device,
wherein the second target region comprises a plurality of detection subregions, each detection subregion is smaller than the first target region and is at least partially overlapped with the first target region, and each laser receiving device receives, in a one-to-one correspondence manner, a laser beam reflected from each detection subregion;
a plurality of laser emission devices, wherein the plurality of laser emission devices are arranged in the emission chamber, the first target region is formed by combining a plurality of emission subregions, and each laser emission device emits a laser beam to each emission subregion in a one-to-one correspondence manner, and
wherein a number of laser emission devices is the same as the number of laser receiving devices, and each laser receiving device receives, in a one-to-one correspondence manner, the laser beam emitted by each laser emission device to and reflected back from the first target region; and
a first emission device, a second emission device, a first receiving device, and a second receiving device, wherein the first emission device emits a laser beam to a first emission subregion, the second emission device emits a laser beam to a second emission subregion, and the first target region is formed by combining the first emission subregion and the second emission subregion, and
wherein both the first receiving device and the second receiving device receive the laser beams reflected back from the first target region;
wherein the casing comprises:
an outer casing, demarcating an inner chamber, wherein the outer casing comprises a first translucent plate and two second translucent plates; and
an inner casing, arranged in the inner chamber, wherein the inner casing is connected to an inner wall surface of the outer casing, and the inner casing divides the inner chamber into the emission chamber and the receiving chamber,
wherein the first translucent plate faces the emission chamber, and laser beams emitted by the first emission device and the second emission device pass through the first translucent plate and are directed outside the LiDAR, and
wherein both the second translucent plates face the receiving chamber, the first receiving device receives the laser beam passing through one of the second translucent plates, and the second receiving device receives the laser beam passing through the other second translucent plate.
