- 物体を撮像するカメラと、
前記カメラにより撮像された第1撮像画像、及び前記第1撮像画像の撮像の後に前記カメラにより前記第1撮像画像と同じ撮像場所が撮像された第2撮像画像を記憶する記憶部と、
前記第1撮像画像と前記第2撮像画像の差を算出し、この差に基づいて、前記カメラの撮像範囲における障害物の有無を判定する障害物判定部と、
前記障害物判定部により前記障害物が有ると判定された場合に、当該判定の結果を報知する処理を行う制御部と、を備える監視システム。 - 前記障害物判定部は、前記第2撮像画像における前記第1撮像画像とは異なる画像領域を抽出して、該抽出した画像領域のサイズを前記差として算出する請求項1に記載の監視システム。
- 前記障害物判定部は、前記第1撮像画像を構成する全画素から各画素を順次選択すると共に、前記第1撮像画像で前記選択した画素と同一の位置にある前記第2撮像画像における画素を対比対象として逐次選択し、当該選択の度に、前記第1及び第2撮像画像から選択した各画素の画素値が異なるか否かを判定して、異なると判定した画素の数をカウントし、当該カウントした画素数が予め設定された規定値以上である場合に、前記画像領域のサイズが閾値以上であるものとし、当該カウントした画素数が前記規定値未満である場合に、前記画像領域のサイズが閾値未満であるものとする請求項2に記載の監視システム。
- 前記第1撮像画像の撮像後に前記カメラによる前記第2撮像画像の撮像が時間をおいて少なくとも2回行われて、これら各第2撮像画像が前記記憶部に記憶され、
前記障害物判定部は、前記第1撮像画像と前記各第2撮像画像とのそれぞれの差を算出し、前記各第2撮像画像についての前記差がいずれも前記閾値以上である場合に前記障害物が有ると判定し、前記各第2撮像画像についての前記差のいずれかが前記閾値未満である場合に前記障害物が無いと判定する請求項1乃至請求項3のいずれかに記載の監視システム。 - 前記障害物判定部は、前記各第2撮像画像についての前記差のいずれかが前記閾値未満である場合、撮像された時が最後である前記第2撮像画像についての前記差が前記閾値未満であるときに限って、前記障害物が無いと判定する請求項4に記載の監視システム。
- 表示部を備え、
前記障害物判定部は、前記障害物が有ると判定した場合に、前記第1撮像画像と前記第2撮像画像を前記表示部に表示させる請求項1乃至請求項5のいずれか1つに記載の監視システム。
