Abstract

The invention discloses a method, device and storage medium for anti-lost early warning, which are used to solve the technical problem that disadvantaged people are easy to get lost in the prior art. In the first image collected by the position, determine the easily lost person; obtain the distance between the easily lost person and other personnel in the first image, and obtain the first distance set; determine all the people within the set radius from the first distance set , to obtain the set of persons to be bound; based on the distance between the easily lost persons and the persons to be bound and the time spent together, determine the bound persons who are bound to the easily lost persons; Monitor the distance and movement track between them. When the distance and movement track exceed the set warning range, it is determined that the person who is easy to get lost is lost; a warning is issued for the loss of the person who is easy to get lost.

Description

technical field [0001] The present invention relates to the security field, in particular to a method, device and storage medium for early warning of loss prevention. Background technique [0002] As people travel more and more conveniently, densely populated places such as railway stations, airports, subway stations, supermarkets, etc. are often high-risk areas for vulnerable groups such as children and the elderly. [0003] In the prior art, family members, relatives and friends, and the police usually help to find vulnerable persons after they are lost, but it is difficult to find them quickly due to the late discovery. [0004] In view of this, how to prevent vulnerable people from getting lost in crowded places has become an urgent technical problem to be solved. Contents of the invention [0005] The invention provides a method for early warning of loss prevention, which is used to solve the technical problem in the prior art that vulnerable people are easily lost i...
