Sensor for automatic doors |
摘要 |
<p>Cameras 51, 52 take images of a predetermined area around a door. A distance measurement unit 53 measures the distance to each object in the taken images. Based on the measured distance, a floor detection unit 54 detects a floor, and an object height/position detection unit 55 detects the height and position of any object other than the floor. A door position detection unit 56 and the door position identification unit 57 specify the position of the door (i.e. open or closed) on the images. A judgement unit 58 judges the presence or absence of an object which is neither the floor nor the door. If an object other than the floor and the door is observed in the images, an output unit 59 produces an object detection signal, so that the door is kept in an open state. <IMAGE></p> |
