Unmanned vehicle safety protection system and method based on solid-state area array laser radar

Abstract

The invention discloses an unmanned vehicle safety protection system based on a solid-state area array laser radar. The system comprises a plurality of solid-state area array radars and a motion control system, wherein the motion control system comprises a protection algorithm module, a navigation control module and a chassis controller, the plurality of solid-state area array radars are respectively arranged at the front part, the rear part and the two sides of the unmanned vehicle, and the solid-state area array radars detect the positions of close-range obstacles around the unmanned vehicleand upload obstacle information to the protection algorithm module. A plurality of solid-state area array radars are closely installed on the four sides of an unmanned vehicle body to detect the positions of short-distance obstacles around the vehicle body, obstacle information is processed by an independently-operated protection algorithm module, a high-priority control instruction is given to the chassis controller, the vehicle body is limited from doing dangerous motion, and the positions of the short-distance obstacles can be accurately measured. The invention further discloses an unmanned vehicle safety protection method based on the solid-state area array laser radar.

Description
