Photoelectricity-navigation-based unmanned road recognition system
2013
The invention discloses a photoelectricity-navigation-based unmanned road recognition system which comprises a vision module, an image processing module, a road recognition module, a speed control module and a steering control module. Turning at a crossroad is mainly achieved through handling a road border, simulating a target trajectory at a track center and recognizing a turning sign. The multi-element PID steering control module and the speed control module realize constantly changing target trajectory when a vehicle rapidly tracks, and realize specified speed and the steering function through identifying color lumps marked by different colors. The intelligent optimized control system is different from a traditional tracking vehicle. The photoelectricity navigation vehicle can realize manless driving without peripheral support through identifying road borders (green belts, fences and the like) in reality and steering signs, thereby having a practical significance.
