Real-time monitoring-based missing child early warning implementation method and device

Abstract

The invention discloses a missing child early warning implementation method and device based on real-time monitoring. The method comprises the following steps: acquiring and detecting a face image appearing on a street in real time; extracting face feature data from the face image by using the trained convolutional neural network; calculating an Euclidean distance between the face feature data and face feature data of each pre-stored missing child portrait image, and judging whether the Euclidean distance is smaller than or equal to a preset threshold value; if the Euclidean distance is smaller than or equal to a preset threshold value, determining that the face image and the pre-stored missing child face image are the same face, and then performing missing child early warning. According to the technical scheme, equipment such as a mobile phone or a vehicle-mounted automobile data recorder is combined with the face recognition technology, the face recognition technology is applied to finding of missing children, the strength of the masses is exerted, and then the success rate of finding the missing children is increased.

Description

technical field [0001] The invention relates to the field of early warning of missing children, in particular to a method, device, electronic device and computer-readable storage medium for realizing early warning of missing children based on real-time monitoring. Background technique [0002] my country has a vast territory and a large population. It is difficult to find missing or trafficked children. In addition, some children are too young to report to the police. It is difficult to find clues. Statistics show that the probability of missing children in my country is only 0.1%. Therefore, it is particularly necessary to mobilize the power of the whole society, give full play to the role of various media, obtain relevant information as much as possible, ask the public for help as much as possible, and capture clues in a timely manner, instead of relying solely on the actions of the children's relatives and the police. [0003] At present, face recognition plays an importa...
