本文提出了一种无线热释电传感器系统，由传感模块（从），同步和错误拒绝模块（主），和数据融合模块（主机），执行人体跟踪。研究了计算工作量在从机、主机和主机之间的分配。不同的信号处理和目标跟踪算法的性能和成本进行了讨论。一个原型系统中描述的热释电传感器模块，能够检测移动的热目标的角位移。菲涅耳透镜阵列用于调制传感器视场。该传感器系统已被用于跟踪一个单一的人类目标。
This paper presents a wireless pyroelectric sensor system, composed of sensing modules (slaves), a synchronization and error rejection module (master), and a data fusion module (host), to perform human tracking. The computation workload distribution among slave, master, and host is investigated. The performances and costs of different signal-processing and target-tracking algorithms are discussed. A prototype system is described containing pyroelectric sensor modules that are able to detect the angular displacement of a moving thermal target. Fresnel lens arrays are used to modulate the sensor field of view. The sensor system has been used to track a single human target.
