PROBLEM TO BE SOLVED: To solve a problem that it is hard to detect and take an appropriate measure with an economical and simple method against an event that a moving body intrudes above a building or premises and takes a picture with an imaging device such as a camera mounted on the moving body.SOLUTION: Imaging devices are installed on the premises or the building toward four directions of east, west, south and north, and an imaging device is installed toward above (right above). Then four directions are consecutively imaged with these imaging devices, and a moving body is detected from a difference in the plurality of consecutively imaged images. Further, distance measurement devices are installed on the premises or the building toward four directions of east, west, south and north, and a distance between each point in the distance measurement range of each distance measurement device and the distance measurement devices is consecutively measured. When a moving body appears in the distance measurement range, and it is detected that the distance between the moving body and the distance measurement device is different from the distance of each of the consecutively measured points, the approach of the moving body is judged.SELECTED DRAWING: Figure 1
【課題】 移動体が敷地内や建物の上空に侵入し、移動体に搭載しているカメラ等の撮影装置により撮影することを、安価でかつ簡単な方法により検知し、適切な対策を取ることが困難であった。【解決手段】 敷地或いは建物の屋上に撮影装置を東西南北四方向に向けて設置し、かつ上方向(真上)に向けても撮影装置設置し、これらの撮影装置で、四方向を常時撮影し、撮影した連続する複数の画面内の画像の相違から移動体を検出する。また、距離測定装置を敷地或いは建物の屋上に撮影装置を東西南北四方向に向けて設置しで、距離測定装置の距離測定範囲内に存在する各点と、距離測定装置との距離を常時測定し、移動体が距離測定範囲内に現れ、移動体と距離測定装置との距離が、常時測定している各点の距離と異なる距離であることを検知し、移動体の接近を検出する。【選択図】図1
