基于红外无线传感器网络的人体跟踪

he goal of our research is to develop a human tracking scheme used in wireless distributed pyroelectric sensor network(WSN).The advantage of thermal human tracking over the optical counterpart lies in its illumination invariance. And it can track multiple human objects inside a room, while maintaining their identities under allillumination circumstances. Fresnel lens arrays are used to modulate the sensor field of view. By collecting and analyzing data, we verified the system performance and accuracy of positioning. Through relevant filtering methods, we processed positioning data and displayed filtered results.
