本論文開發出一套以攝影機為基礎的非接觸式心率量測裝置。並設計實驗針對裝置量測精準度、量測範圍、適應性濾波器成效等進行探討。而在裝置精準度驗證的部分,針對趴姿態與坐姿態時的量測數值進行驗證,發現在趴姿態時裝置精準度為98.74%,而坐姿態時則為98.61%。在裝置量測範圍的實驗當中也發現,感測範圍為36bpm~300bpm。而在適應性濾波器成效探討的部分也發現,可以讓使用者在有較多動態雜訊產生的情形之下亦能還原出生理訊號,有助於訊號雜訊比的提升。
The thesis developed a camera based non-contact heart rate measurement device. Besides, there is a accuracy and sensoring range verification of our proposed system, and also investigation of the adaptive filter performance for blind source separation. On the device accuracy verifying section, we verified the accuracy on two postures including lying posture and sitting posture, and measured heart rate from these two posture of each subject. And the device accuracy report of lying posture and sitting posture are 98.74% and 98.61% separately. On the other hand, the device sensoring range verifying section, it shows that sensoring range is between 36 bpm to 300 bpm. Furthermore, the adaptive filter has good performance at reducing motion artifact.
