Study and Implementation of Key Techniques in Vehicle Speed Measurement Through Video

Aiming at solving the problems of low accuracy,low robustness to shadows and incapability of measuring multiple vehicle speed simultaneously in current methods,this paper introduces a new vehicle speed measurement method based on the model for vehicle speed measurement through video.A vehicle speed measurement system through video based on this model has achieved satisfactory results,and the error rate of the speed measurement is below 3 percent in some conditions.
