Traffic flow measurement by video image processing
Toshiaki Hashimoto, Shunji Murai · Close-Range Photogrammetry Meets Machine Vision · 1990
A traffic flow control system is necessary for preventing accidents and lighting congestion in the motorization era. The system should be provided with the functions to measure the 2-dimensional movement of each vehicle on a comparably wide area. This paper describes a study on a new traffic flow measurement system by processing periodically acquired video images. The system can decide the size of each vehicle and measure its 2-dimensional movement.
