An object detection systemincludes a sensor sectionconfigured to detect an object within a detection area A; and an adjuster (remote controller)configured to interactively communicate with the sensor section. The adjusterincludes; a transmission unitconfigured to transmit a setting signal for setting an operating condition of the sensor sectionto the sensor section; an adjustment notification unitconfigured to receive a completion signal of operating condition setting from the sensor sectionand give notification of the operating condition, setting of which has been completed; and a target selection unitconfigured to arbitrarily select a target sensor sectionintended for the operating condition setting.

Object detection system

An object detection systemincludes a sensor sectionconfigured to detect an object within a detection area A; and an adjuster (remote controller)configured to interactively communicate with the sensor section. The sensor sectionincludes a driving machineconfigured to adjust the detection area A. The adjusterincludes a transmission unitconfigured to transmit, to the sensor section, a setting signal for setting an operating condition of the sensor sectionincluding adjustment of the detection area A by the driving machine; and an adjustment notification unitconfigured to receive a completion signal of operating condition setting from the sensor sectionand subsequently give notification of the operating condition, setting of which has been completed.

An authentication registration/invalidation apparatus is provided, which allows easy invalidation of an authentication tag when the authentication tag is lost, and facilitates management of authentication tags. When an RFID reader () receives an RFID signal including an instruction of invalidation, which is transmitted from an operation tag () in a recognition area (A), an invalidation unit () sets an operation mode to an invalidation enabled mode. If an RFID tag recognizer () recognizes an authentication tag () before or after the setting of the invalidation enabled mode, the invalidation unitinvalidates the authentication tag (), or invalidates all authentication tags () that belong to a group to which the authentication tag belongs.

To provide a traffic monitoring apparatus capable of accurately determining the number of objects present in an area under surveillance without being affected by the difference in arrangement of those objects. Included is an object information acquiring deviceA for acquiring three-dimensional object information D related with an object H present in an areaunder surveillance, and a determining deviceA for determining the number of objects based on at least a volume, which is one of a volume and a height of an object obtained from the object information D.

Traffic monitoring apparatus

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.
