A detection method of a three-dimensional garage safety detection system based on machine vision

Abstract

The invention relates to the technical field of stereo garage safety detection, and specifically relates to a safety detection system for a stereo garage based on machine vision, and a detection method thereof. The safety detection system for a stereo garage based on machine vision comprises a distance measuring sensor, a camera, a controller, and a display screen. The distance measuring sensor and the camera are fixed on a side wall corresponding to a door in a garage, and height of the camera is higher than height of a vehicle. A display is fixed beside a garage door. The sensor, the camera,and the display are connected with the controller. In detection, a three-frame method is firstly used for the system to detect motion conditions around the vehicle, and then close conditions of vehicle doors are detected. In a detection process, the system is not influenced by light, and detection accuracy is high.

Description

technical field [0001] The invention relates to the technical field of three-dimensional garage safety detection, in particular to a detection method of a three-dimensional garage safety detection system based on machine vision. Background technique [0002] In recent years, with the improvement of people's living standards, the number of private cars has also increased year by year, which has brought about the problem of parking difficulties. In order to solve the problem of many cars and small places, the three-dimensional garage came into being. In the process of using the three-dimensional garage, safety is the primary issue, and it is also the pain point. At present, for the safety detection of the three-dimensional garage, the longest use is the camera detection based on machine vision. Camera detection based on machine vision is an active detection method that requires image processing to automatically handle possible security issues and respond to alarms in a timel...

Problems solved by technology

However, in the existing process of using a vision-based camera to detect parking, it may be affected by the light of the car lights, and the car door may not be closed properly, and the equipment will be lifted and started, causing safety accidents; There is a certain randomness, and the existing camera detection cannot recognize it; and when the user closes the safety door of the vertical tower library, if the alarm is called, the situation in the library cannot be judged at the first time, which brings a lot of inconvenience to the user
