Automatic door control and anti-pinch system based on binocular stereoscopic vision and method thereof

Abstract

The invention discloses an automatic door control and anti-pinch system based on binocular stereoscopic vision and a method thereof. The system comprises a control device, a power assembly, a human body detection module, a door state detection module, and an image collection device, wherein the power assembly, the human body detection module, the door state detection module and the image collection device are connected with the control device. The image collection device obtains image and video data of a glass door area; the human body detection module performs semi-global stereo matching andfeature extraction on left and right images acquired by a camera by using a neural network so as to detect a human body; the door state detection module processes acquired videos and images to obtainobstacle detection and automatic door state recognition results; the control device is connected with a motor device through a control wire; and the control device sends out a correct instruction according to detection information of the human body detection module and the door state detection module to control the power assembly to drive a glass door to move to achieve anti-pinch. According to the automatic door control and anti-pinch system based on the binocular stereoscopic vision and the method thereof, a binocular stereo vision technology is adopted, and due to the characteristics of non-contact, passivity, high accuracy and good real-time performance of the binocular stereo vision technology, the binocular stereo vision technology is very suitable for human body detection and speedand distance measurement application in the automatic door opening and closing process.

Description

technical field [0001] The invention relates to an automatic door control system, in particular to an automatic door control and anti-pinch system and method based on binocular stereo vision. Background technique [0002] In today's modernization, urbanization is getting faster and faster, and there are countless high-rise buildings. With the development of construction and transportation industries, the automatic door industry has also developed rapidly, and has been widely used in many fields, greatly improving people's lives. Nowadays, automatic doors are not only popular in cities, but almost every household in rural areas has also begun to install automatic doors. Today's rural house gates are generally installed with two kinds of doors at the same time, with security doors installed inside, and then automatic doors are added to the outer layer of the security doors. The living habits in rural areas are different from those in cities. During the day, the doors of house...

AI Technical Summary

Problems solved by technology

1) If an animal has been moving within the range of the sensor, the sensor door will also work, which makes the sensor door always in the working state of the switch, resulting in easy damage and failure of the sensor system

2) The detection of automatic doors mainly adopts two technologies of contact touch panel and infrared light curtain, but both of them have certain defects

3) Most of the existing automatic door-opening systems for houses use objects within the sensing range of sensors to automatically open the door through the controller, and some are equipped with smart cards. It meets the general needs, but it brings inconvenience to special groups, such as the elderly, children and the disabled. certain security risks
