Automobile doubling auxiliary system based on camera and control method thereof

Abstract

The invention discloses an automobile doubling auxiliary system based on a camera. The system comprises a sensor module, a single-chip microcomputer module, an intelligent vehicle steering engine module and a power supply management module. The invention also discloses a control method. Images in front of driving of the corresponding vehicle are acquired through videos, then road boundary information is sought by performing median filtering, dynamic threshold segmentation and other methods, and then speed and steering control is performed on the vehicle body by using the boundary information. Closed loop incremental PID control is performed on the speed so that the control period can be obviously shortened, acceleration and deceleration are enabled to be further timely and the speed is smoother. Closed loop PD control is performed on steering so that steering of the steering engine is enabled to be more sensitive and the effect of early prejudgment can be achieved. Therefore, the doubling auxiliary function can be realized, and the vehicle driving process is enabled to be safer and more reliable by the automobile doubling auxiliary system based on the camera and the control method thereof in comparison with the systems and the methods in the prior art.
