RFID (radio frequency identification) label and person corresponding relationship establishment and trajectory tracking method and device

Abstract

The embodiments of the present invention disclose an RFID (radio frequency identification) label and person corresponding relationship establishment and trajectory tracking method and device. According to the method and device, a plurality of face images are divided into a plurality of image groups, wherein the face images in each image group belong to the same person; corresponding relationships between the image groups and RFID labels, namely corresponding relationships between the persons and the RFID labels, are established according to the face images and the acquisition time and acquisition positions of the RFID labels; and the trajectories of the persons are tracked through using the RFID labels corresponding to the persons according to the corresponding relationships between the persons and the RFID labels. Compared with a method using face images acquired by a face image acquisition device to track the trajectories of the persons in the prior art, the method does not need to capture face images in a whole process so as to avoid the influence of equipment and environment, and can track the trajectories of the persons according to the tracking of the RFID labels even under dark conditions or conditions where the definition of equipment is low or no face image acquisition devices are adopted.

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
