| Abstract: | A vision-based lane departure and rear-end collision warning system in car is developed in this paper,which can be applied to the structural road environment where the main obstacles are vehicles.Through plentiful features in input images such as intensity,texture and shape,the lane and the preceding vehicle are detected and tracked.According to the situation,distinct orders and warnings are given to the driver.The construction and main functions of the system are introduced,and a flow chart is drawn.Then some key technologies such as the algorithm for locating the road and the preceding vehicle in the input frames and the warning method are discussed.Experiments are also conducted to validate the feasibility and the validity of the system. |
