Recently, the importance of vehicle speed analysis from video images in traffic accidents and incidents has been increasing, and with the development of camera technology, there is an urgent need to improve image analysis technology. Among the influencing factors, the complexity of the frame rate due to digitization of video signals, and the time difference of imaging within the same frame due to the rolling shutter method of CMOS cameras are thought to influence the accuracy of vehicle speed analysis.
