Multi-beam laser radar and self-moving vehicle

Abstract

A multi-beam laser radar includes a rotating prism, a rotating mechanism, and two transceiver modules. The rotating prism includes at least three side surfaces around a scanning rotation axis of the rotating prism; at least two of the at least three side surfaces are reflecting surfaces, and in all reflecting surfaces, included angles between at least two of the reflecting surfaces and the scanning rotation axis of the rotating prism are unequal. The rotating mechanism drives the rotating prism to rotate around the scanning rotation axis. The two transceiver modules are positioned at two sides of the rotating prism respectively and asymmetrical with respect to the scanning rotation axis, an included angle formed by laser emitting surfaces of the two transceiver modules is less than 180 degrees, such that scanning fields of view in at least two directions are formed when the rotating prism rotates around the scanning rotation axis.
