Abstract
A heat trace region extraction device includes: a difference actual object image generation unitthat generates a difference actual object image which is an image of a difference between an actual object image which is an image of an actual object obtained by photographing a certain range with an actual object camera for photographing the actual object and a background actual object image which is an actual object image of a background of the certain range; a difference thermal image generation unitthat generates a difference thermal image which is an image of a difference between a thermal image which is an image of heat emitted by the actual object obtained by photographing the certain range with a thermal camera for photographing the heat emitted by the actual object and a background thermal image which is a thermal image of the background; and a heat trace region extraction unitthat extracts a heat trace region by removing a region of the actual object from the thermal image based on the difference actual object image and the difference thermal image.
