본 논문에서는 시나리오형 가설 객체 추적이라는 객체 추적 방법을 제안한다. 제안된 방법에서는 객체와 객체의 이동 방향을 감지할 수 있는 센서 노드를 사용하여 실내 모니터링 영역을 여러 개의 폐쇄형 마이크로 셀로 구분합니다. 무선 멀티홉 네트워크를 통해 센서 정보가 추적 서버에 축적되고, 추적 서버에서 객체 추적이 수행된다. 센서 정보로부터 물체의 궤적을 추정하기 위해 가상 마이크로 셀과 가상 물체로 구성된 가상 세계의 새로운 개념을 도입합니다. 가상 마이크로 셀에서는 센서 정보에 따라 가상 객체가 생성, 전송, 삭제됩니다. 좁은 통로에서 지나가는 물체의 속도가 느려지는 등 마이크로 셀 내 물체의 특정 움직임을 처리하기 위해 가상 객체 간의 상호 작용에 따른 가상 객체 생성도 고려합니다. 또한, 객체 추적 실패 횟수를 줄이기 위해 추적 서버가 센서 정보의 손실을 추정할 때 가상 객체를 생성한다. 시뮬레이션을 통해 가상 객체 간의 상호작용을 고려하여 추적 성공률이 최대 29% 향상되는 것을 확인했습니다. 또한, 센서 정보 손실을 고려하여 추적 성능이 최대 6% 향상되었습니다.

Abstract: In the present paper, we propose an object tracking method called scenario-type hypothesis object tracking. In the proposed method, an indoor monitoring region is divided into multiple closed micro-cells using sensor nodes that can detect objects and their moving directions. Sensor information is accumulated in a tracking server through wireless multihop networks, and object tracking is performed at the tracking server. In order to estimate the trajectory of objects from sensor information, we introduce a novel concept of the virtual world, which consists of virtual micro-cells and virtual objects. Virtual objects are generated, transferred, and deleted in virtual micro-cells according to sensor information. In order to handle specific movements of objects in micro-cells, such as slowdown of passing objects in a narrow passageway, we also consider the generation of virtual objects according to interactions among virtual objects. In addition, virtual objects are generated when the tracking server estimates loss of sensor information in order to decrease the number of object tracking failures. Through simulations, we confirm that the ratio of successful tracking is improved by up to 29% by considering interactions among virtual objects. Furthermore, the tracking performance is improved up to 6% by considering loss of sensor information.
