IMAGING APPARATUS FOR AUTOMATICALLY IMAGING SUBJECT

PROBLEM TO BE SOLVED: To provide a method for automatically and accurately discriminating whether a person or the like can be caught in a field of a camera that is installed at a specific position, when imaging the person with the camera.SOLUTION: Signals transmitted from multiple transmitters each transmitting a radio wave of a specific signal are received by a receiver. A value of a combination of reception strengths of the signals is compared with a value of a combination of levels of a reception strength that is recorded beforehand and enables imaging by a camera, thereby discriminating whether a person having the receiver can be imaged, and the person is automatically imaged. When recording the reception strength beforehand, in a case where the person having the receiver is caught in an image of the camera, the combination of levels of the reception strength at that time is recorded as a position where the person can be imaged by the camera. The combination of levels of the reception strength is mechanically learnt as input data and whether the person can be imaged by the camera is mechanically learnt as output data, thereby providing a simplified discrimination method for associating the combination of levels of the reception strength with the position where the person can be imaged by the camera.SELECTED DRAWING: Figure 1 【課題】特定の位置に設置したカメラで、人物等を撮影する場合に、その人物がカメラに写るかどうかを自動的に精度よく判別する方法を得る。【解決手段】特定の信号の電波を発信する複数の送信機から発信された信号を受信機で受信し、それぞれの信号の受信強度の組み合わせと、あらかじめ記録したカメラで撮影可能な受信強度の強弱の組み合わせの値とを比較することで、その受信機を持つ人物を撮影可能かどうか判別し、自動的に撮影する。受信強度をあらかじめ記録する際に、カメラの画像に受信機をもつ人物が写っている場合には、その時の受信強度の組み合わせはカメラで撮影可能な位置であるとして記録し、受信強度の組み合わせを入力データ、カメラで撮影可能かどうかを出力データとし、機械学習することで、受信強度の組み合わせとカメラで撮影可能な位置の関連付ける簡易な判別方法を得る。【選択図】図１
