Object tracking apparatus and method, and sensor position designating method

摘要

The apparatus for tracking an object and the method thereof and the method for locating a sensor are described. The subject object tracking apparatus comprises an interface receiving sensor information and object information from a sensor communicated with an object; a first storing part successively storing sensor information in chronological order; a second storing part storing a neighborhood graph displaying an object space; and a location determining part determining a location of an object using sensor information and a neighborhood graph. According to the present invention, an accessibility graph corresponding to a space is generated and a location of a sensor is determined on an accessibility graph, thereby effectively locating a sensor and tracking an object.

主权项

1. An object tracking apparatus, which is provided to track a location of an object by communicating with a plurality of sensors, the apparatus comprising:
an interface configured to receive sensor information and object information from sensors communicated with the object; a first storing part configured to successively store the sensor information, the sensor information comprising moving path in a space of one or more tags of objects identified by a plurality of sensors; a second storing part configured to store a neighborhood graph displaying an object space information, the object space information comprising a white node, a black node, and a link, the black node neighboring to the white node; and a location determining part configured to determine real-time location of the object using the sensor information and the neighborhood graph, wherein in response to detection of the sensor information detected by the one or more sensors, the location determining part is caused by a processor to determine the white node corresponding to a detecting sensor transmitting the sensor information, and to determine, using the neighboring graph, a subspace corresponding to a black node neighboring to the white node as a location of the object, if not receiving the sensor information from the plurality of sensors.
