In this paper, the entrance person reception system which uses the FG vision sensor is proposed as a person's behavior observation system. In this system, the observation is carried out by using the 3-D shape data obtained from the FG vision senor which is one of the range sensors. As an experimental examples, the FG vision sensor is installed at the top of the door. It is recognized whether it is a person who comes in, or a person who just passes, by detecting the behavior of the man who is here in front of the door. Even if there is a man of the wheelchair or a child, the height information of the object is not used so that the recognition may be carried out precisely. In this system, the recognition is done by the inclination information of the local plane.
