碩士 === 國防大學理工學院 === 電子工程碩士班 === 102 === The number of heartbeats per unit of time is one of the important information for health index. So far, the medical products have the function to detect the heart rate by contact with any point on the body. However, the medical personnel could have difficulty to contact the wounded personnel with the skin, such as the premature baby in an incubator, bone fracture, or some patients who are not suitable to contact with his/her body. Therefore, the traditional medical equipments can’t detect the heartbeat directly by contact with the skin. This thesis proposes a non-contact detection system to detect the heart rate. The proposed system uses an image capture equipment to capture the images from human face. Then, a heartbeat detection algorithm is proposed to analyze the heartbeats. The previous studies focused on short distance to detect the heartbeats, because the brightness of the skin will decay according to the capture distance. In the thesis, a heartbeat detection algorithm with an image enhancement is proposed to resolve the distance problem.
