Elevator trapped person detection method based on computer vision

Abstract

The invention discloses an elevator trapped person detection method based on computer vision. The method comprises the following steps that S1, an elevator scene video is collected through a camera ofan elevator car; S2, whether closing duration of an elevator door of the elevator car exceeds a set threshold value or not is judged, if yes, the step S3 is executed, and if not, the step S1 is executed again; S3, a convolutional neural network model for the elevator scene video is constructed; and S4, the number of people in the elevator scene video is identified by using the convolutional neural network model, and a number result of people in the elevator car is fed back to a monitoring center. According to the elevator trapped person detection method based on the computer vision, the elevator trapped situation can be found in time, so that elevator safety and passenger satisfaction are improved, and the elevator taking safety is guaranteed; compared with a traditional method, the elevator trapped person detection method has the advantages that the two models are constructed to effectively recognize door opening and closing of the elevator car and the number of people in an elevator, more accurate elevator information can be provided, and a better reference effect is achieved for maintenance personnel and the monitoring center.

Description

technical field [0001] The invention belongs to the technical field of elevator monitoring, and in particular relates to a method for detecting a person trapped in an elevator based on computer vision. Background technique [0002] With the development of society, the rhythm of people's work and life is constantly accelerating, and the elevator, which is a tool that people must use in daily life, is also gradually developing at a high speed. The main components of the elevator are composed of the following: traction system, guidance system, car, door system, weight balance system, electric drive system, electrical control system and safety protection system. [0003] In the elevators that are usually used, there will be a call for help alarm button inside the elevator. If a passenger is trapped inside the elevator, you can press the call button to call the police. For normal calls, there are false alarms in this calling method. In the process of our daily elevator ride, som...
