摘要

A top-view sensing approach is proposed in this paper for infrared radiation object motion detecting and localization with binary pyroelectric infrared detectors. We develop a modulation strategy based on the radial distance and Gray code to obtain the horizontal distance between the sensor node and object. Firstly, the field of view of Fresnel lens array in a sensor node is modulated to achieve single degree of freedom spatial partition, and then the localization algorithm is proposed to coordinate multiple sensors nodes to achieve two degrees of freedom spatial partitions. The tracking experiment shows that the method proposed here has the advantages in computational efficiency and high accuracy.
