Crowd marking method and system, computer equipment and readable storage medium

Abstract

The invention relates to a crowd marking method and system, computer equipment and a readable storage medium. The crowd marking method comprises the following steps: marking crowds; obtaining an activity feature of a first detection target in the detection image, and under the condition that the activity feature is a preset activity feature, marking a first detection target, matching the detectiontarget with a face library through the detection image and a second detection target marked in a preset range of the first detection target, obtaining a matching object of the detection target, and classifying the matching object according to the marked category of the matching object. Through the invention a problem that a group closely contacted with a suspected person cannot be determined because the group is subjected to target detection through an infrared thermal imaging technology in the related technologies can be solved, thus achieving the positioning and tracking of the group closely contacted with the suspected person in an epidemic prevention and control process, and improving the confirmation efficiency of the epidemiological contact history of the suspected person.

Description

technical field [0001] The present application relates to the technical field of image processing, in particular to a method, system, computer equipment and readable storage medium for crowd marking. Background technique [0002] With the rapid development of science and technology, infrared thermal imaging technology is more and more widely used in the field of security technology. Through infrared thermal imaging technology, the staff can clearly see the temperature distribution of the object or human body surface in the monitoring screen, combined with the visible light image, they can accurately see the visual image of the current object or human body and the movement of the measured object or human body. In the process of epidemic prevention and control, it is a more efficient monitoring method to monitor densely populated people through infrared thermal imaging technology. [0003] In related technologies, infrared thermal imaging technology is used to combine infrare...
