Multi-point monitoring camera device

多点監視カメラ装置

Abstract

PROBLEM TO BE SOLVED: To solve the problems that conventionally when a camera is moved to a another position or angle of view which has been preset, image recognition becomes unstable, and erroneous recognition results are output, so that sufficient detection of instruction abnormalities cannot be made, when monitoring at a plurality of positions and of viewing angles is performed by the use of the image recognition by a monitor camera, in which a pan-tilt or zoom is possible. SOLUTION: After a focusing positioning by presetting, and after an operation of autofocusing, or the like, image recognition is conducted by images in a state of completing a focus adjustment and obtaining the stable image, thereby obtaining superior invasion abnormality detection results. Further, since by combining the focusing positioning by the presetting with the operation of autofocusing, it is possible to shorten focus adjustment time, and to quicken the start and completion time of the image recognition, and to enhance performanced intrusion detection.

(57)【要約】 【課題】パンチルトやズームが可能な監視カメラによ り、複数の位置や画角での監視を、画像認識を用いて行 う場合、予めプリセットされた異なった位置や画角へカ メラを移動する度に画像認識が不安定となり、誤った認 識結果を出して十分な侵入異常検出が行えないという課 題があった。 【解決手段】プリセットによるフォーカス位置合わせ 後、またはオートフォーカス動作後等、フォーカス調整 が完了し安定した画像が得られた状態の画像で画像認識 を行なうことにより、良好な侵入異常検出結果を得るこ とができる。またプリセットによるフォーカス位置合わ せとオートフォーカス動作を組み合わせることで合焦の 調整時間が短縮し、画像認識の開始及び完了時間を早 め、侵入検出の性能を向上することができる。
