Abstract: The people counting device includes an image acquisition unit to acquire an image from an imaging device, a head coordinate detection unit to detect a head coordinate of a target person from the image, a foot coordinate estimation unit to estimate a foot coordinate of the target person from the detected head coordinate, an individual region detection unit to perform region segmentation of the image and to give an attribute to each of regions, a foot coordinate correction unit to determine whether the target person overlaps another person based on the given attribute and to correct the foot coordinate of the target person estimated by the foot coordinate estimation unit when the persons are determined to overlap each other, a foot coordinate region inside/outside determination unit to determine whether the foot coordinate exists in a detection region set in the image, and a people counting unit to count foot coordinates.
