| 中文摘要: |
| 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。 |
| 英文摘要: |
| At present,due to the limitations of the pyroelectric infrared (PIR) sensor in static human detection,a method is proposed for dynamic PIR,sensor using a combination of static and dynamic detect ion,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 detection line meets personnel targets,measurement values of angle wil l be acquired through the frame difference method,then multiple sensor values of cross location are fused,and fi nally 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. |
