A Measuring System for Traffic Flow of Passers-by by Processing ITV Image in Real Time

A bsfracl We h e &cussed the algon'thm rho1 such primitive srmc paromelers ~zs rhe number of passers-by, their moving direction and moving ~ p e d can be concurrenlIy measured by processing LV i m g e in real time wirh a personal computer. In this olgorirhm, the movement of a passer-by is displayed in [he form of o locu fine on a cross section imagc. Tkrefore, by counting rhe number of locus lines and calcuhring tk grdienr of the locus liner, we can meawe t he number of passers-by rogether wirh ihe moving direelion and moving speed. We impfentenred this aIgosilhm on the system consisring of on TTV camera, an image processor and a personal computer. Using this system in a real situation, we cou!d measure the above mentioned puramelers within 5% and2096 of memurind error in case of a ligh! r r m c pow and a heavy rrafic flow, respecrively.
