A human body identification method includes a monitoring target region capturing step of obtaining a range image of a monitoring target region using a range image camera, a normal vector image calculation step of calculating a normal vector image, a template preparation step of preparing, as a template, a normal vector image from a range image captured so as to include at least a head portion of a human body, a template scaling step of scaling the size of each template based on range information that is a pixel value, a human body corresponding region estimation step of estimating at least one region corresponding to a human body, and a number-of-persons determination step of determining the number of human bodies based on a logical sum of the at least one region estimated as corresponding to a human body.
