THRONGING DETERMINATION DEVICE AND THRONGING DETERMINATION METHOD

摘要

The present invention has: an image input unit (2) into which moving images are input; an image division unit (3) that divides an input image into local areas; a motion detection unit (5) that detects motion in each of the local area images resulting from the division; a person detection unit (6) that detects whether persons are included in the local area images resulting from the division; and a thronging determination window generation unit (9) that generates a thronging determination window that is formed with multiple local areas. The thronging state in the input image is determined on the basis of a motion ratio, which is obtained from the ratio of the local areas which are contained in the thronging determination window and for which the motion detection unit (5) has determined that motion is present, to the local areas contained in the thronging determination window, and on the basis of a person ratio, which is obtained from the ratio of the local areas which are contained in the thronging determination window and for which the person detection unit (6) has determined that a person is present, to the local areas contained in the thronging determination window.
