| 摘 要: 室内跟踪定位技术中，RFID技术造价低、无接触、识别快速，成为室内跟踪定位的主要选择。本文采用 无源RFID跟踪，通过信号强度信息推知目标和参考标签的距离，给出目标的位置估计，然后结合网络摄像头在可见区 域通过视频图像辅助对跟踪目标进行精确定位，并给其在绝对坐标系中的坐标。最后将目标与RFID标签坐标位置相比 较，得到正确的目标位置和ID。 |

| Abstract: In the indoor track positioning technology,the RFID technology becomes the main choice,because of the low cost,no touch,rapid identification.In this paper,the passive RFID tracking technology is applied to deduce the distance of the target and the reference tag,and provides the location of the object based on the signal strength information.In the visible region,the tracking target is accurately positioned,and its coordinates in the absolute coordinate system is provided with the aid of video images in the web camera.Finally,compared with the coordinates of the RFID tag,the exact location and ID of the target are obtained |
