Pyroelectric Infrared Biometric Systems for Real-Time Human Identification

使用紅外線熱電感測器實現人員即時辨識之生物檢測系統

摘要


在本研究中我們提出新穎的光學運算感測系統,在系統中引入生物測定觀念以及非成像式之光學特徵擷取技術來捕捉步行者之動態熱像特徵,加上智慧型特徵分類訓練法則,成功地實現了人員即時辨識。 在特徵分類辨識方面,本論文發展出兩套分別以類比式生物特徵以及數位式生物特徵為基礎的生物檢測/辨識系統。我們成功的展示藉由適當的感測模組結構,加上特徵擷取方法以及特徵訓練演算法,這些生物檢測系統可以達成固定行走路線及自由路線的即時人員辨識並有非常好的辨識效果。

In this study, we proposed novel designs for computational systems that use biometrics and non-conventional imaging approaches to capture thermal motion features of humans to achieve real-time path-dependent and path-independent gait for human identification. We have developed two pyroelectric infrared (PIR) feature-generating sensor systems. One system is analog, the other digital, and both are derived from the signals generated by humans crossing the detection areas. We successfully demonstrate that by selecting suitable sensor configurations and feature extraction/training algorithms, the sensor systems are capable of performing human identification.
