Abstract

The present invention specifically relates to a method, device, computer equipment and storage medium for checking close contacts. By reading all the surveillance videos in the surveillance area, the frame in which the new crown patient first appeared in all the surveillance videos is determined, and the frame containing The frame of the new crown patient is obtained from the image sequence of the new crown patient. Through the first image recognition method, the person who is in contact with the new crown patient is identified as a close contact, and the close contact is framed, and the frame including the close contact is output as Picture, frame the objects that will be touched in all the surveillance videos, determine whether the new crown patient has touched the object through the second image recognition method, and if there is a touch, frame the object that the new crown patient contacts, and determine through the second image recognition method Whether the pedestrian has contact with the object. The present application not only improves the detection accuracy and detection efficiency, but also reduces the detection difficulty.

Description

technical field [0001] The application belongs to the field of screening of close contacts of infectious diseases, and in particular relates to a method, device, computing device and storage medium for screening close contacts using image technology. Background technique [0002] At the beginning of 2020, the new crown pneumonia raged, posing a huge threat to people's health. In order to effectively control the spread of the epidemic, detailed epidemiological investigations are required. Among them, the exclusion of close contacts is an important task. At present, close contacts are mainly checked manually. On the one hand, the workload of the investigation is heavy, and on the other hand, the investigation is not accurate enough. Treating them all as close contacts will cause a large error. If only contacts of patients with new crowns are regarded as close contacts, there may be fish that slip through the net. [0003] At present, there are some screening technologies, su...
