Human body detector lens

To provide an object detecting device having a capability of sufficiently adjusting the detection areas to suit to the environment in which it is installed, the object detecting device includes an antenna AT for emitting a detecting beam to the detection areas and receiving a portion of the detecting beam which has been reflected from the detection areas, and adjusting coversandcovering a front portion of the antenna AT and operable to adjust respective figurations of the detection areas. The adjusting coversandare selectively fitted one at a time to the front portion of the antenna AT for defining a different figuration of the detection areas. When one of the adjusting covers, that is, the coverthat is formed with a pair of cutoutsandfor suppressing the side lobe of the detecting beam is selectively used, the detection areas can be defined having no unnecessary detection areas.

Object detecting device

Cameras take images of a predetermined area around a door. A distance measurement unit measures a distance from the cameras to each object in the taken images. Based on the measured distance, a floor detection unit detects a floor, and an object height/position detection unit detects a height and position of any object other than the floor. A door position detection unit and a door position identification unit specify position of the door (i.e. open or closed) in the images taken by the cameras. A judgement unit judges 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 taken by the cameras, an output unit produces an object detection signal, so that the door is kept in an open state.
