| titleOfInvention | A method of based on graphical pixel localization quantitative judge austenitic stainless steel surface iron pollution |
| abstract | A method of based on graphical pixel localization quantitative judge austenitic stainless steel surface iron pollution, belonging to material surface detection technique field.Step are as follows: configuration iron pollution tests solution, is affixed on sample surfaces after test paper dipping, carries out color developing detection and Image Acquisition to sample；It automatically extracts the RGB color chromatic value of adjustment image different location and R, G, B coordinate array data is converted into the coordinate array data with L, a, b of Lab chrominance representation；With a, (x, y, a) source data that coordinate array data are reconstructed as graphical pixel use the stainless steel colour developing value that does not pollute as calibration benchmark；Revised colour developing coordinate array data are made into three-dimensional position-colour developing figure, and colour developing value is substituted into the standard spectrum relevant to iron pollution grade pre-established and compares assessment, determine pollution position and content.The present invention can austenitic stainless steel hierarchical detection to different pollution levels, improve detection accuracy. |
