Embodiment Construction

[0097] The present invention will be further described below in conjunction with specific examples.

[0098] Such as figure 1 As shown, the escalator floor board video monitoring method combined with machine vision and infrared array described in this embodiment mainly monitors the floor board area by analyzing the movement speed and direction of objects and passengers on the escalator floor board. In this method, using the temperature difference characteristics of the object and the passenger, the imaging of the two under the infrared array sensor is significantly different, and the infrared image of the passenger is detected and tracked. Compared with other traditional target detection methods, the infrared image is more simple , it is easier to identify, therefore, the camera and infrared array sensor should be installed directly above the floor plate of the escalator, such as figure 2 As shown, the specific situation is as follows:

[0099] 1) Video image and infrared i...

Abstract

The invention discloses an escalator floor plate video monitoring method by combination of machine visual sense and infrared array. The method includes the steps of acquiring video images and infrared images, 2) coordinate registering for the video images and infrared images, 3) using CodeBook algorithm to establish a background model, extracting article and passenger foreground images, 4) using infrared images to detect pedestrians in foreground images, 5) using a Kalman filter to track passenger targets, 6) using Fitzgibbon algorithm to conduct contour detection and ellipse fitting for the foreground images, 7) eliminating passenger targets in 6) and using the Kalman filter to track article targets, and 8) monitoring the floor plate area by analyzing the moving speed and moving direction of the articles and passenger center coordinates. Articles and passenger behavior on an escalator floor plate can be detected and analyzed through the algorithm. When abnormity occurs, an emergency solution can be timely started to minimize the potential damage of the abnormity.

Description

technical field [0001] The invention relates to the field of image pattern recognition and the field of elevator production technology, in particular to a video monitoring method for floor boards of an escalator combined with machine vision and infrared arrays. Background technique [0002] In a modern society where escalators are becoming more and more popular, various safety issues follow. With the rapid development of science and technology and the increasing awareness of people's safety, video surveillance has become an effective tool for public management and decision-making. Auxiliary means. Nowadays, the video monitoring of escalators mostly stays in the stage of manual monitoring with image information as the main content. When an abnormality or accident occurs, the monitoring personnel often make the situation worse because they cannot respond in time or take corresponding measures. Today, with increasing labor costs, it is impossible to assign emergency personnel ...
