Image analysis-based detection and alarm system for child taking elevator alone

Abstract

The invention discloses an image analysis-based detection and alarm system for a child taking elevator alone. A multi-view camera is used as an information acquisition port to read the distance data of people entering an elevator, an RGB camera extracts a portrait area in a picture when the elevator is started, when the area is guided back to the shot picture, portrait part characteristics in a shot picture are read, scanning is conducted through a TOF camera, a personnel three-dimensional model is established, and the personnel three-dimensional model i combined with part characteristic dataof a portrait to establish a real three-dimensional portrait model, thereby judging whether a child enters the elevator or not; all real three-dimensional model data entering the elevator are comparedwith information pre-stored in a database, whether a child entering the elevator enters the elevator alone or not is judged, and therefore alarming, reminding and persuasion are conducted. Accordingto the method, the situation that children take the elevator alone is effectively avoided, alarming, reminding and persuasion are carried out when the children take the elevator alone, and accidents caused by the fact that children take the elevator alone are avoided.

Description

technical field [0001] The invention relates to the technical field of elevator safety systems, in particular to a detection and alarm system for children riding alone in an elevator based on image analysis. Background technique [0002] In today's society, elevators have become an indispensable tool in people's lives. While elevators bring various conveniences to modern people's lives, accidents and tragedies such as elevator slipping, elevator failure, and elevator outage occur frequently. , has brought harm to countless families, especially children who take elevators, especially children who take elevators alone. Because children are small and mischievous, they are easy to jump around in elevators and press buttons indiscriminately, resulting in a sharp increase in elevator accidents. Immature, unable to effectively call for help when the elevator fails, and easily make dangerous actions in the elevator, resulting in injury or even death. Therefore, children riding in el...
