Study for detection methods of traffic parameters based on EPI

摘要

It is a key segment of the traffic management system about detecting traffic parameters. With the continuous development of computer vision, the video traffic detection method is paid more and more attention. It is constructed that an Epi-polar Plane Image(EPI) method reflect the surface and movement characteristics of the vehicle, then the EPI is processing of normalization, filtering and texture detection. Finally, based on the EPI, it is given about the detection methods of mean velocity and length of the vehicle, traffic flow.
