New technologies are required to obtain information related to humans, such as their physical position or posture. Many methods are used for human body detection, although image processing is the most popular because it can obtain more information than the others. However, image processing cannot detect a human who does not move when the background is complicated. We propose combining image processing with an estimation of the size of a human body with a scanning pyroelectric electric sensor. When the pyroelectric sensor scans, the volume of the heat source in the rotatory direction is measured. A heat source domain is provided from the image information of the camera photography range. In addition, the position of the person can be measured similarly to stereo-camera measurement if scanned by two sensor units at the same time. In this work, results of measurement by a prototype are discussed.
