Method and device for establishing corresponding relationship between rfid tags and personnel and trajectory tracking

Abstract

The embodiment of the present invention discloses a method and device for establishing a corresponding relationship between an RFID tag and a person and tracking a trajectory. Multiple face images are divided into multiple image groups, and the face images in each image group belong to the same person. According to Acquisition time and location of face images and RFID tags, establish the corresponding relationship between image groups and RFID tags, that is, establish the corresponding relationship between personnel and RFID tags. According to the established corresponding relationship between personnel and RFID tags, the trajectory of the personnel is tracked using the RFID tags corresponding to the personnel, compared to the prior art that only uses the face images collected by the face image acquisition equipment to track the trajectory of personnel The method does not need to collect face images in the whole process, avoiding the influence of equipment and environment. Even in the dark, low-resolution equipment or no face image acquisition equipment, it is possible to track personnel based on RFID tags. Trajectory tracking.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method and device for establishing a corresponding relationship between an RFID tag and a person and tracking a trajectory. Background technique [0002] In daily life, there are many situations where it is necessary to track personnel trajectories. For example, when events such as theft or robbery occur, it is necessary to track the trajectories of personnel involved in the event. [0003] At present, face image acquisition equipment is usually used to track personnel trajectories: set up face image acquisition equipment in various locations such as roads and public places, and use the data collected by face image acquisition equipment to determine the time and place of the appearance of a specific person. Track the trajectory of that particular person. [0004] However, using this method, the environment and equipment will greatly affect the data collection effect. In...

Problems solved by technology

[0004] However, using this method, the environment and equipment will greatly affect the data collection effect. In the case of dark or low-resolution equipment, it is impossible to accurately determine the time and place where a specific person appears, so it is impossible to accurately Tracking of personnel trajectories; or face image acquisition devices cannot be installed in some locations, so personnel trajectories cannot be accurately tracked
