Cold area steel plate automatic feeding method based on machine vision

Abstract

The invention provides a cold area steel plate automatic feeding method based on machine vision, and belongs to the technical field of machine vision tracking. According to the method, monitoring cameras are installed on the operation side of a cold area steel plate feeding roller way at equal intervals for each group of roller ways, the cameras are used for shooting the steel plate state on the roller ways and the traveling position state respectively, whether steel plates exist on the roller ways or not is judged through the image processing technology, and the distance from a traveling vehicle to the surfaces of the roller ways is calculated; and then starting and stopping of the roller ways are determined according to different combinations of the roller way steel plate state and the traveling state, and therefore automatic feeding of the cold area steel plates is achieved. The problems that a traditional photoelectric detection signal cannot judge traveling feeding, the detection range is not comprehensive and the like are solved, and the method has the advantages that equipment cost is low, installation is simple, and accuracy is high; and manual operation can be completely replaced, unmanned and intelligent cold area feeding roller ways are achieved, and huge economic benefits are brought to application sites.

Description

technical field [0001] The invention relates to the technical field of extremely visual tracking, in particular to an automatic feeding method for steel plates in a cold zone based on machine vision. Background technique [0002] At present, the feeding process of the steel plate cold zone production line is mostly controlled by manually watching the monitoring video of the roller table to control the start and stop of the roller table. When the driving is loading, the operator observes the driving and turns off the roller table rotation switch in the operating room. After driving away, it is confirmed that there are steel plates on the roller table and then the roller table rotation switch is restored to carry out the transportation of the steel plates. [0003] In the process of promoting the automation of feeding, there are also technologies that use light detection signals to determine the presence or absence of steel plates on the roller table. When there are steel plat...

AI Technical Summary

Problems solved by technology

Although this solution has achieved automation to a certain extent, it cannot track the state of the driving. During the loading process of the driving, it is easy to interfere with the light detection signal, and it cannot accurately control the start and stop of the roller table. Moreover, due to the complex environment of the factory , Dust and other reasons can easily lead to damage to the light inspection equipment, high maintenance costs, unable to fully realize automatic feeding
