Title:

PRISM AND MULTI-LAYER LASER RADAR

Document Type and Number:

WIPO Patent Application WO/2021/175141

Kind Code:

A1

Abstract:

The embodiments of the present application disclose a multi-layer laser radar and a self-moving vehicle. The multi-layer laser radar comprises a rotating prism, a rotating mechanism, and two transceiving assemblies; the rotating prism comprises at least three side surfaces, and the at least three side surfaces are provided around a scanning rotation axis, wherein at least two side surfaces are reflective surfaces, and among all reflective surfaces of the rotating prism, there are at least two reflective surfaces forming unequal angles with the scanning rotation axis of the rotating prism; the rotating mechanism is used for driving the rotating prism to rotate around the scanning rotation axis; and the two transceiving assemblies are respectively located at either side of the rotating prism, and the two transceiving assemblies are asymmetrically provided with respect to the scanning rotation axis, and an angle between laser emission surfaces of the two transceiving assemblies is less than 180 degrees, so as to form, when the rotating prism rotates around the scanning rotation axis, a scanning field of view corresponding to at least two directions.
