Multiple Lane Detection Algorithm Based on Optimised Dense Disparity Map Estimation
share
Lane detection is very important for self-driving vehicles. In recent years, computer stereo vision has been prevalently used to enhance the accuracy of the lane detection systems. This paper mainly presents a multiple lane detection algorithm developed based on optimised dense disparity map estimation, where the disparity information obtained at time t_n is utilised to optimise the process of disparity estimation at time t_n+1. This is achieved by estimating the road model at time t_n and then controlling the search range for the disparity estimation at time t_n+1. The lanes are then detected using our previously published algorithm, where the vanishing point information is used to model the lanes. The experimental results illustrate that the runtime of the disparity estimation is reduced by around 37 detection is about 99
