[0025] Such as figure 1 As shown, a multi-line scanning forward-looking anti-collision lidar device includes a laser emitting system, a polyhedron rotating scanning system, a laser receiving and detecting system, and a control drive system. The laser emitting system includes a laser 3 and a collimator 4, and the laser 3 is connected with the collimator 4; the polyhedron rotary scanning system includes a polyhedron drum 6, a rotary motor and a photoelectric pair 11. The rotating motor is connected with the polyhedron drum 6, which can drive the polyhedron drum 6 to rotate. The upper end of the polyhedron drum 6 is provided with a polyhedron reflector 13, and the lower end of the polyhedron drum 6 is a uniformly divided sawtooth structure. The photoelectric pair 11 is arranged on the lower end of the polyhedron drum 6, and the rotation angle of the polyhedron drum 6 can be tested; the laser receiving and detecting subsystem includes a perforated mirror 5, a receiving lens 8, an ...
