PROBLEM TO BE SOLVED: To provide a device and a program for detecting a fault in an imaging apparatus.SOLUTION: In a plurality of imaging apparatuses capable of independently controlling exposure, photographed images imaged to include overlap regions, which represent overlapped imaging regions, are acquired respectively (S130). Then, the overlap regions in the acquired plurality of photographed images are extracted (S140), to extract image characteristics (the distribution of brightness and colors i.e. a histogram, object types recognized in the region, etc.) in the extracted plurality of overlap regions (S150). Further, the image characteristics in the plurality of overlap regions are compared, so that whether or not the image characteristics are similar is judged (S160). When the image characteristics are not similar, the imaging apparatus is judged to be faulty (S230).
【課題】撮像装置の故障を検出する装置及びプログラムを提供する。【解決手段】それぞれ独立して露出制御可能な複数の撮像装置にて、重複した撮像領域を表す重複領域を有するように撮像された撮像画像をそれぞれ取得するS130。そして、取得した複数の撮像画像において重複領域をそれぞれ抽出しS140、抽出した複数の重複領域においてそれぞれ画像特徴(輝度や色彩の分布(ヒストグラム)、この領域内において認識された物体の種別等)を抽出するS150。また、複数の重複領域における画像特徴を比較し、これらの画像特徴が類似するか否かを判定しS160、これらの画像特徴が類似していない場合に撮像装置が故障していると判定するS230。【選択図】図2
