The invention provides a travel close contact monitoring method and device, and the method comprises the steps: obtaining a video image shot by a camera, calibrating each pedestrian in the video image based on a detection model obtained through pre-training, and determining whether each pedestrian wears an anti-propagation object or not. And constructing every two pedestrians into a group of pedestrian pairs, and calculating the distance between the two pedestrians in each pedestrian pair. Whether the distance between the two pedestrians is a safe distance or not is judged on the basis of a set first judgment threshold value and a set second judgment threshold value so as to determine whether the two pedestrians are in a close contact state or not, and the second judgment threshold value is determined according to the anti-propagation article wearing conditions of the two pedestrians. According to the scheme, on the basis that pedestrian calibration and anti-propagation article wearing condition determination are achieved through image processing and an artificial intelligence algorithm, the judgment threshold value is dynamically set based on the anti-propagation article wearing condition of the pedestrian to judge the close contact state of the pedestrian, and the reliability of distance measurement is improved.
本申请提供一种出行密接监控方法和装置,通过获取摄像机拍摄的视频画面,并基于预先训练得到的检测模型标定出视频画面中的各个行人,且确定各个行人是否佩戴防传播物品。将每两个行人构建为一组行人对,计算各个行人对中两个行人之间的距离。基于设置的第一判断阈值和第二判断阈值,判断两个行人之间的距离是否为安全距离,以确定两个行人是否处于密接状态,而第二判断阈值为根据两个行人的防传播物品佩戴情况所确定。本方案中,在利用图像处理及人工智能算法实现行人标定和防传播物品佩戴情况确定的基础上,基于行人的防传播物品佩戴情况动态设置判断阈值来判断行人的密接状态,提高了距离度量的可靠性。
