The design background:
Workers according to the color standard sample color card, stick good color card by artificial than one now if there is a wrong color,

Design concept:
Standard color swatches photos first, and then color swatches for quality inspection by the conveyor belt into image acquisition device image collection, with the standard sample after image than

Question:
1. As the image than what to do, because want to check if each color piece stick a wrong color
2. Because it is artificial, each color of the same color piece may have a position deviation (not too much deviation)
3. If there is a grain area will affect than

Great god answer, have a better idea to forget or a similar project glad

CodePudding user response:

And there may be color piece color very close

CodePudding user response:

Just choose each color piece in the middle part of comparison,

CodePudding user response:

Recommend the use of hand-held color scanner, can save 100 samples, used on the real scanning, can according to sample, you can extract the SDK to the manufacturer also interface file, programming the calculation sample data into the software,

CodePudding user response:

Baidu "color recognition of OpenCV" can get you need the answer!!

CodePudding user response:

OpenCV support c + +

CodePudding user response:

Delphi has a BItMapData source very good use of baidu once have documentation
Can look for the color center find edges is simple can modify Settings, and so on source code is can be a bit slow

CodePudding user response:

This relatively simple, color is the color of the large repeat, so the location is very easy, check also easy to take RGB color deviation judgment directly
