Abstract

The embodiment of the invention provides a personnel identification method and device, and the method comprises the steps: obtaining a pedestrian detection and pedestrian tracking result of a current image of video data; for a first pedestrian tracked in the current image, judging whether a first human body image of the first pedestrian in the current image and a second human body image of the first pedestrian in an adjacent previous frame image are the same person or not; when the first human body image and the second human body image are the same person, using a first person identifier of the first pedestrian in the previous frame image as a person identifier of the first pedestrian in the current image; and when the first human body image and the second human body image are different persons, determining that the pedestrian tracking result of the first pedestrian is wrong, and performing person identification on the first human body image again. According to the invention, the personnel identification rate and the accuracy of the identification result can be improved.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular, the present invention relates to a method and device for identifying a person. Background technique [0002] In the field of character behavior analysis, cameras are usually used to collect video data, and then video analysis technology is used to detect the state, behavior and interrelated information of people. For example, there is a need to apply person identification in different domains. Specifically, in the retail field, shopping malls need to apply unconscious personnel identification to provide customers with high-quality services; in the industrial field, factories need to apply personnel identification to monitor the production activities of each worker; in the elderly care field, nursing homes use personnel Identify and monitor the daily behavior and physical condition of each elderly person. [0003] Common non-contact person recognition technologies...
