FPGA prototyping of vehicle trajectory display for reverse parking - A state of the art survey

摘要

This paper discloses an efficient method to display the vehicle trajectory for reverse parking. The major problem that inexperienced drivers face today is the difficulty in reverse parking the vehicle. To alleviate this difficulty, the proposed system has a display unit inside the vehicle which provides an overlay that indicates as to how the vehicle should be traversed. The system includes a rear view camera and a display unit which superimposes the trajectory calculated, on the image obtained from the camera. Dynamic overlay algorithm, which involves only linear equations, is developed to show the vehicle path with marked distances as the vehicle is turning during reverse. This is calculated by obtaining the steering angle from the vehicle and calculating the coordinates that should be connected by segments.
