Abstract

The invention discloses a method and system for detecting the state of an elevator door based on 3D measurement technology, wherein the method includes the following steps: obtaining data including 2D contour, depth map and 3D point cloud of the elevator door area through a 3D sensor; obtaining data according to the 3D sensor Manually set the elevator door area through the user interface; or automatically set the elevator door area based on statistical analysis of the data collected by the 3D sensor; use the discontinuity of the data obtained by the 3D sensor to calculate the opening degree of the elevator door; according to the current elevator The degree of door opening judges whether the elevator door is completely closed or fully opened; judges whether the elevator is opening, closing, abnormal door gap detection, and repeatedly opening and closing the door according to the historical information of the door opening degree; calculates the door area according to the data obtained by the 3D sensor and sends it to the 3D sensor The depth-related information of the door area; the abnormal opening detection of the door is performed according to the depth-related information of the door area.

Description

technical field [0001] The invention belongs to the technical field of elevator safety, and in particular relates to an elevator door state detection method based on 3D measurement technology. Background technique [0002] Elevator is a very popular public facility, which is widely used in shopping malls, office areas, residential areas and other scenes, bringing great convenience to people's daily life. However, due to the influence of factors such as incorrect use and untimely maintenance, elevators occasionally break down. Elevator door failure is the most frequent failure among many elevator failures, and there are many types of elevator door failures. The sudden opening of the door during operation may cause passengers to fall, and failure to open the door may lead to trapped people. Therefore, it is accurate And real-time detection of the state of the elevator door is a very critical link to ensure the safe operation of the elevator. [0003] 3D measurement technolog...
