Document Type and Number:
WIPO Patent Application WO/2022/037345
Kind Code:
A1
Abstract:
A detection method (100) of a laser radar (200), the laser radar (200), and a vehicle system (300) comprising same. The laser radar (200) may rotate around a rotation axis thereof, and comprises an emission unit (210) having a plurality of lasers (211). The detection method (100) comprises: step S101, controlling a plurality of lasers (211) to emit detection laser beams so that the laser radar (200) has non-uniform horizontal angle resolution; step S102, receiving echo waves reflected by the detection laser beams on a target and converting same into electrical signals; and step S103, calculating a distance and/or reflectivity of the target according to the electrical signals. Hence, horizontal angle resolution of the laser radar (200) is flexibly configured, time of flight and power consumption are reduced, and a ranging range of the laser radar (200) is improved.
