A moving object detecting method and a system therefor are provided to obtain a bipolar difference image and divide noise from a moving object by using spatial distribution of two images. A difference image unit(100) generates a bipolar difference image by using a previous image and a current image. A distance value calculation unit(200) generates a supply node and a consumption node from a plus image and a minus image of the bipolar difference image. The distance value calculation unit generates a supply-consumption graph by using the supply node and the consumption node. A compensation value calculation unit(400) calculates a compensation value with regard to noise occurring between a previous image and a current image by using a calculated distance value. An object motion detection unit(300) detects movement of an object by using a compensation value about the calculated noise. |
