| Zusammenfassung: | To more accurately measure the heartbeat on the basis of an image.SOLUTION: A heartbeat measurement system S comprises an image data acquisition unit 211, a pulse wave signal detection unit 213, and a heartbeat measurement unit 215. The image data acquisition unit 211 acquires a plurality of images generated by continuously imaging a measurement object person as a subject. The pulse wave signal detection unit 213 detects a pulse wave signal being a signal indicating pulse wave components of the measurement object person on the basis of the change of a value expressing a color between the plurality of images. The heartbeat measurement unit 215 detects the timing of the heartbeat in the pulse wave signal by analyzing the cross correlation between the pulse wave signal and a model signal being a model of the waveform indicating the heartbeat, and measures the heartbeat of the measurement object person on the basis of the detected timing of the heartbeat.SELECTED DRAWING: Figure 3
【課題】画像に基づいた心拍に関する測定を、より精度高く行う。【解決手段】心拍測定システムＳは、画像データ取得部２１１と、脈波信号検出部２１３と、心拍測定部２１５と、を備える。画像データ取得部２１１は、測定対象者を被写体として連続撮影することにより生成された複数の画像を取得する。脈波信号検出部２１３は、複数の画像の間における色を表現する値の変化に基づいて、測定対象者の脈波成分を示す信号である脈波信号を検出する。心拍測定部２１５は、脈波信号と、心拍を示す波形のモデルであるモデル信号との相互相関を解析することで脈波信号における心拍のタイミングを検出すると共に、該検出した心拍のタイミングに基づいて測定対象者の心拍に関する測定を行う。【選択図】図３ |
