本文提出了一种限于人体肢体运动特征红外感知的方法并用实验下该方法在轻量级人体生物信息获取中的应用效果。本文的传感方法采用了热释电红外传感阵列来获取由人体运动产生的生物信息。人体运动生物特征信息由一个双层结构获取过程组成:在底层由物理层的热释电红外传感阵列组成的限于肢体运动的感和层,本层具体关注多角度多肢体局部的细粒度运动特征感知;上层的运动特征感知组成全局的逻辑识别综合分析,本层通过综合同步身体体域级的运动信息合成生物特征,本文提出的传感方法在多人约束路径步态识别了进行实验,并采用矢量识别技术进行了验证获得了较好的识别效果。

This paper presents a limb-specific infrared sensing paradigm and its application in building a lightweightbiometric system. The proposed sensing paradigm explores the novel use of pyroelectric infrared （PIR） sensor arrays inpursuit of unifying biometric feature acquisition and motion capturing into an infrared sensing framework. A two-layerstructure is used to organize the biometric feature acquisition process： the limb-specific sensing is physically implementedwith PIR sensor arrays at the bottom layer, which focuses on capturing the limb-level biometrics associated with walker＇slimb-level movements from multi-view; the global locomotion is logically characterized at the top layer, which synergies thebody-level biometrics to exhibit the coordination habits of walker＇s limb-level movements. The application of the proposedsensing paradigm to lightweight human identification is addressed in the context of the path-constrained walker recognitionwith the vector quantization technique. Experimental studies are conducted to validate the proposed method.
