ABSTRACT
This paper presents a novel velocity estimation method for ground vehicles. The task here is to automatically estimate vehicle speed from video sequences acquired with a fixed mounted camera. The vehicle motion is detected and tracked along the frames using optical flow algorithm. The distance traveled by the vehicle is calculated using the movement of the centroid over the frames and the speed of the vehicle is estimated. The accuracy of our method was calculated by measuring the velocity manually and comparing with calculated values. The application is developed using MATLAB and SIMULINK.
