Problems solved by technology

Due to the computational complexity of the algorithm, the real-time performance of the tracking is not good
In addition, due to the occlusion or influence of other objects in the image, the tracking accuracy is not high
[0003] On the other hand, for object tracking, due to the various shapes of objects, it is difficult to perform feature extraction based on camera images, so it is difficult to track objects of arbitrary shape.

Abstract

The invention discloses an intelligent tracking and monitoring system based on RFID label signal intensity. The intelligent tracking and monitoring system based on RFID label signal intensity is characterized by comprising a tracking and monitoring area, an active RFID label worn by a person or an object, tracking network cameras, RFID readers, a network interchanger and a PC server, wherein the tracking network cameras and the RFID readers are distributed above the tracking and monitoring area in a grid shape, and the rectangular area defined by the four RFID readers on the outermost portion forms the tracking and monitoring area. The intelligent tracking and monitoring system based on RFID label signal intensity analyzes the movement trend by collecting the changes of the signal intensity of the 2.4GHz active RFID label worn by the person or the object and correspondingly controls a camera cloud deck, thereby accurately realizing tracking and monitoring.

Description

technical field [0001] The invention relates to a video tracking system for people or moving objects, in particular to an intelligent tracking and monitoring system based on the signal strength of an RFID tag. Background technique [0002] The video tracking technologies in the prior art are all realized by pure image feature processing technology. Some algorithms track the person's head, and some algorithms track the person's outer contour to realize the person tracking. Due to the computational complexity of the algorithm, the real-time performance of the tracking is not good. In addition, due to the occlusion or influence of other objects in the image, the tracking accuracy is not high. [0003] On the other hand, for object tracking, due to the various shapes of objects, it is difficult to perform feature extraction based on camera images, so it is difficult to track objects with arbitrary shapes. [0004] In the application of safety area management or production mana...
