Abstract(in English) This paper proposes a method for detecting known objects quickly in 3D environments and estimating the object positions with multiple pan-tilt-zoom cameras. Our search method, Dynamic Active Search, reduces the number of camera operations by predicting the existence of a target in wide angles, zooming in on a promising area, and confirming the target. Even when many reference images taken under various camera angles and various scales need to be searched for, Dynamic Active search is devised to detect the object efficiently. With multiple cameras, object detection and object localization become more efficient. Experiments show that by Dynamic Active Search using four cameras both search speed and position estimation accuracy are improved six times compared with a single-camera/active-search-without-prediction configuration.
