Zusammenfassung: | To provide a possessed object inspection device capable of improving a detection rate of a possessed object by reducing oversight of a small possessed object.SOLUTION: A possessed object inspection device has a passive system for inspecting a possessed object by receiving a blackbody radiation 2 radiated from an object so as to image the object. The blackbody radiation is reflected against a polygon mirror 3 including a plurality of reflectors 4, 5 different in size. The reflected blackbody radiation is collected by a single condensing mirror 6 so as to be made incident to a detector 9. Detected images different in image size are synthetically processed so as to inspect the possessed object. Synthetic imaging processing where the images different in image size (resolution) are combined is performed and the images are fitted in image size, so as to reduce oversight of a small possessed object and also to improve a detection rate of dangerous materials such as a cutting tool, a firearm, and an explosive substance.SELECTED DRAWING: Figure 1
【課題】小さい所持物の見落としを低減し、所持物の検知率を向上できる所持物検査装置を提供する。【解決手段】所持物検査装置は、物体から放射される黒体輻射2を受信して画像化し、所持物を検査するパッシブ方式である。黒体輻射をサイズが異なる複数の反射鏡4,5を備えるポリゴンミラー3で反射し、反射した黒体輻射を単一の集光ミラー6で集光して検出器9に入射させ、検出した画素サイズの異なる画像を合成処理して所持物を検査することを特徴とする。画素サイズ(解像度)の異なる画像を組み合せた合成画像化処理を行い、画像の画素サイズを揃えることによって、小さい所持物の見落としを低減できるとともに、刃物や銃器、爆発物などの危険物の検知率を向上できる。【選択図】図1 |
