A method and system for detecting dangerous behaviors of elevator passengers based on 3D measurement technology

Abstract

The invention discloses an elevator passenger dangerous behavior detection method and system based on a 3D measurement technology. The method embodiment comprises the following steps that a depth mapor 3D point cloud data of an elevator door area are obtained through a 3D sensor; a detection area is manually set according to the data acquired by the 3D sensor through a mode including a user interface; or statistical analysis is carried out according to the data acquired by the 3D sensor, and then the detection area is automatically set; the upper boundary data of the detection area are analyzed according to the data acquired by the 3D sensor, whether the spatial position is continuous or not is judged, and if yes, an elevator is in a door closing state; and when the elevator is determinedto be in a door closing state, then in the detection area, passenger lean door behavior detection is carried out according to the plane characteristics of an elevator door, if the collected data arenot matched with the plane characteristics, it is judged that passenger lean door behavior exists.

Description

technical field [0001] The invention belongs to the technical field of elevator safety, and in particular relates to a method for detecting dangerous behaviors of elevator passengers based on 3D measurement technology. Background technique [0002] Elevator is a very popular public facility. It is widely used in shopping malls, office areas, residential areas and other scenes, bringing great convenience to people's daily life. However, due to factors such as incorrect use and untimely maintenance , the elevator occasionally fails. Door failure is the most frequent failure among many elevator failures, and there are many types of door failures. Among them, the sudden opening of the door during operation may cause passengers to fall, and the failure of the elevator to open the door normally may cause trapped people. Blindly trying to save yourself by opening the door without the basic safety knowledge of the elevator often leads to secondary injuries. It is very important to...

Problems solved by technology

This solution ensures the safety of the elevator doors through a mechanical device. The disadvantages of this technical solution are as follows: there are already a large number of stock elevators in the real scene, and it is impossible to replace all the elevator doors; the production and implementation costs are high, and it is difficult to obtain large-scale elevators.
