摘要
针对目前热释电红外(PIR)传感器在静态人体检测方面的局限性,提出了一种在动态下利用多PIR传感器、动静相结合对人员目标进行检测、测向与定位的方法。研究中,感知节点上的静态PIR传感器对人员目标进行测距,动态PIR传感器以10°/s的速率对监控区域往复式扫描,变被动为"主动"。当人员目标与PIR传感器的探测视线相交时,通过帧差法得到目标的角度值,融合多个传感器的测量值进行交叉定位,实现了在探测区域对整个目标事件过程的有效数据采集。实验证明,本文方法能很好地对不同状态下的人员目标进行检测定位,具有实用价值。
At present,due to the limitations of the pyroelectric infrared （P1R） sensor in static human de- tection,a method is proposed for dynamic PIR, sensor using a combination of static and dynamic detec- tion, location and direction finding of target. In the study, the static PIR sensor on sensing node is used to measure the distance of personnel targets,but the dynamic PIR sensor with the speed of 10~/s is used to monitor the region by reciprocating scanning,which changes from ＂passive＂ to ＂active＂. When the detec- tion line meets personnel targets, measurement values of angle will be acquired through the frame differ- ence method, then multiple sensor values of cross location are fused, and finally the whole process of the target event of effective data are collected in the detecting area. Experimental results show that different state personnel targets are well detected and located with this proposed method.
