Automatic detection method and system of copper grains in foam nickel

Abstract

The invention provides an automatic detection method and system of copper grains in foam nickel. The method comprises the following steps of: configuring a plurality of colorful image collection devices for collecting foam nickel furnace images at upper and lower sides of a conveying worktable of the foam nickel; imputing image data collected by the colorful image collection devices into an industrial computer to carry out white balance filtering; then converting an RGB (Red, Green, Blue) color space into an HSV (Hue, Saturation, Value) color space; after converting, carrying out middle value filtering based on an H channel; setting a foam nickel surface region with a detected H channel differentiated value as a copper grain region, wherein H is more than 80 and less than 180; setting one part except the region to be a non-copper region; respectively representing the copper grain region and the non-copper region by gray values 255 and 0, so as to obtain a binary image; finally, carrying out region growth on a white region in the binary image and finding out an exterior rectangle; further determining whether copper exists or not through a classifier which is studied and trained by taking the exterior rectangle as a candidate region; if so, sounding a warning and waiting for a worker to process.

Description

technical field [0001] The invention relates to an automatic detection method and system for copper particles in foamed nickel. Background technique [0002] With the continuous enhancement of human awareness of environmental protection, oil resources are decreasing year by year, and oil prices are gradually rising. Reducing automobile pollution and saving energy have become serious problems faced by governments all over the world. Battery technology and the production, transportation, storage, and cost of hydrogen severely restrict the development of electric vehicles and fuel cell vehicles. In hybrid vehicles, due to the use of high-power energy storage devices Providing instantaneous energy to the car can reduce engine size, improve efficiency, reduce emissions and fuel consumption, and can recover energy during braking and deceleration. [0003] Ni-MH batteries have the characteristics of high specific power, many cycles, large current charge and discharge, no memory ef...

Problems solved by technology

[0006] The application of domestic Ni-MH batteries in automobiles is still in the stage of research and development, mainly because nickel foam, the main raw material of Ni-MH batteries, contains copper impurities and cannot meet the standards for use in automobile batteries.
