The Research Of Color Measurement Instrument Based On Regression Algorithm

Color is one of the most important objective attribute of material in the world. Expression of color only limited to the subjective description vocabulary, let alone quantitative measurement for a long time. With the development of society, real-time, convenient, quantitative standardized color detection technique and color examining instrument have more and more using value. The realization of traditional instrument based on spectrum method and the visual color method already had some application in the market, but in very conditions. The former needs to gather the continuous spectrum characteristic of the object but the organization is complicated, the latter, because the subjective judgement depending on the operator, precision is not good.This paper set out from colormetry and basic principle of regression algorithm at first. With the analysing of mathing principle in colormetry, this paper leading the regression algorithm into color measurement. According to colorimetry principle, regression algorithm have obtained good result in used in color transformation of different color space match, mathing in color space and color measurement is one problem essentially, therefore can know according to the same principle, the method that regresion algorithm is be able to be used to measure a color, and making color instrument is possiable. The creative of this paper is leading regrssion algorithm into the field of color measurment based on mathing theory in color space .and also Set up liquid color measurement instrument with this principle, and discuss accuracy with diffirent regression model. Furthermore the color emulation recurrence program is generated on PC for theintuitionistic comparison of measurement result.The experimental result indicates that color instrument based on regression algorithm obtains the good precision in lab, and testing in some diffirent regression mode can introduce precision in evidence. The portable liquid color examining instrument runs steadily, and it get higher precision than the visual type color instrument. It is believed that this research results can widen the application of traditional color instrument.
