| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | We have proposed an object tracking method called Scenario-type Hypothesis Tracking. The proposed method divides a wide monitoring region into multiple closed micro cells, and pairs of infrared sensors are placed at borders among micro cells to detect objects and their moving directions. The sensor information is gathered to a tracking server through wireless networks, and the tracking server maintains virtual micro cells and virtual objects which indicate a variety of hypotheses of object trajectory. Virtual objects are generated, moved, and deleted in virtual micro cells appropriately based on sensor information and behavior of other virtual objects. The number of virtual objects greatly increases when the number of micro cells and the object density increase, which results in the increase of system load. In this report, we modify the generation method of virtual objects to decrease the number of generated virtual objects while keeping object tracking accuracy. In addition, we extend our method to handle losses of sensor information due to packet loss, failure of sensing, and functional limitation of sensors. Through simulation evaluations, we confirm that the number of generated virtual objects is decreased by about 25% while keeping object tracking accuracy when the tracking server fails to gather sensor information. | |
