摘要
物联网领域室内运动目标识别与跟踪是当今研究与应用的热点。提出一种基于RFID识别定位技术与CCD视频信息相融合的室内运动目标识别跟踪方法。首先利用RFID及提出的扩展虚拟参考标签定位方法对目标进行身份识别与粗定位,利用此信息指导多CCD开启或休眠,应用背景差分法对CCD监控图像检测目标并进行多视角融合实现较精确定位,最后通过加权平均得到运动目标位置。该方法融合了RFID快速识别定位及CCD视频定位准确的优点,实验结果表明,提出协作信息融合方法可有效提高室内目标跟踪准确度与实时性。
Indoor moving target recognition and tracking in Intemet of Things is a popular research and application topic in recent years. This paper proposes an indoor moving target recognition and tracking method based on RFID and CCD collaborative information fusion. First, RFID technique and the proposed extended VIRE approach are used to recognize and coarsely locate the target. Second, based on the coarse localization results, the monitoring/sleeping control of different CCDs is realized. Then background difference method is used to detect the target in CCD monitoring image and realize precise localization with multiple angle of view fusion. Finally, with weighted average of the two localization results the moving target location is obtained. The method combines the advantages of RFID fast recognition and localization and CCD precise localization. The experiment results indicate that the proposed collaborative information fusion method can effectively improve the accuracy and real time performance of indoor moving target tracking.
