Embodiment Construction

[0043] In order to make the above-mentioned features and advantages of the present invention more comprehensible, the following specific embodiments are described in detail in conjunction with the accompanying drawings.

[0044] The invention utilizes the identification of RFID and the high precision of visual positioning to realize online detection and tracking of targets, and further fuses the position information of the two to improve the positioning accuracy. figure 1 It is a work flow chart of the inventive method, mainly divided into the following four stages:

[0045] The first stage is the RFID guidance stage, using RFID information for positioning to obtain the area range of the target, guiding vision for target detection, and greatly reducing the scope of target detection and search.

[0046] The second stage is the target detection stage. After the camera is calibrated and time synchronized, the image detection algorithm is used to detect the moving target.

Abstract

The invention discloses an indoor monitoring method based on RFID and vision fusion, and belongs to the field of computer vision and internet of things security, an RFID reader, a tag and a commercial camera are used, an RFID object and a vision object are matched through an association algorithm, and RFID and vision position information is fused through a DS evidence fusion algorithm. On-line detection and tracking of the target are realized by using the identifiability of RFID and the high precision of visual positioning, and the precision and robustness of target positioning are improved.

Description

technical field [0001] The invention belongs to the field of computer vision and Internet of Things security, and in particular relates to an indoor monitoring method and system based on RFID and vision fusion. Background technique [0002] In recent years, the ability to detect and track people and devices in indoor environments has greatly expanded the development of location-based services, such as indoor navigation, transportation, security monitoring, etc. Indoor localization is easily affected by object occlusion and irregular motion of people, and these scenarios are more complex than outdoor environments. Therefore, existing localization techniques mainly focus on the fusion of multiple detection sensors. Visual surveillance is the primary way to monitor the location, behavior and activities of people. Surveillance cameras are widely used in public places, especially security-sensitive areas, and the number of cameras is huge. Surveillance video has become the lar...
