摘要： There is provided a human detection device capable of determining whether a human exists in an infrared image with information only contained in the infrared image at high speed with high accuracy regardless of an ambient environment temperature. The human detection device includes: a boundary information extracting unit which receives infrared image data and detects a boundary of a small image region based on a pixel value of a pixel to specify a boundary pixel; a distance converting unit which calculates a shortest distance between each pixel contained in the small image region and the boundary pixel; a processing unit which extracts a pixel having the shortest distance satisfying a predetermined condition, from the pixels contained in the small image region; and a determining unit which performs pattern matching by comparing image data with a predetermined pattern based on the pixel having the shortest distance to determine whether an object shown in the small image region is a human.
