Velocity Estimation for Autonomous Vehicles Based on Image Analysis

Stereo vision is widely used in many 3-D image applications. In this paper, a system based on stereo vision concepts has been developed with the goal to measure the velocity of vehicles using images. Using this method, an autonomous vehicle is able to measure its velocity using only a single camera. From a sequence of images, the method uses techniques to locate homologous points and then estimates the velocity of the vehicle. The experimental results validate the application of the proposed method to autonomous vehicles.
