Abstract
The purpose of this research is to develop an automatic door system, which can provide intelligent opening and closing operations. The automatic door is not opened when a pedestrian just passes by the door. In order to judge the intention of the pedestrian whether he wants to pass through the door, we detect the pedestrian's skeleton data, joint orientation, and 3D coordinates by using Kinect sensor. In this paper, we analyze the behavior of pedestrians from the extracted features, and propose a method what can calculate width of pedestrian and the appropriate timing of opening operation for only whom determining to pass through the door.
