【摘要】：顏色測量設(shè)備獲取的光譜數(shù)據(jù)或色度數(shù)據(jù)應(yīng)能夠真實客觀的表征物體的顏色信息。針對不能直接與測量儀器接觸的測量目標,需要采用非接觸式顏色測量方法獲取其顏色信息。根據(jù)光譜輻射度理論分析可知,非接觸式顏色測量過程中照明距離、測量距離及曝光時間的變化對測量結(jié)果有較大影響,而已有研究成果中并未深入研究測量參數(shù)的變化對測量結(jié)果的影響。為了在非接觸式顏色測量過程中得到準確的結(jié)果,提出了一種基于正交試驗的非接觸式顏色測量參數(shù)的最優(yōu)化方法。實驗通過光譜輻射度計(PhotoResearch705,Photo Research公司,美國)獲取不同參數(shù)組合條件下標準色卡(GretagMacbeth ColorChecker Rendition Chart)的顏色信息,結(jié)合極差分析法和方差分析法,實驗結(jié)果顯示測量值與標準值的色差CIEDE2000最小為0.878 8ΔE,最大為1.543 1ΔE,表明該方法能有效的選取最佳參數(shù)組合,并能分析各參數(shù)對測量結(jié)果影響的大小。
[Abstract]:The spectral data or chrominance data obtained by the color measurement device should be able to represent the color information of the object objectively and truthfully. The non-contact color measurement method is needed to obtain the color information for the target which can not be directly contacted with the measuring instrument. According to the spectral radiance theory, the variation of illumination distance, measurement distance and exposure time in the process of non-contact color measurement has great influence on the measurement results. The effect of the change of measurement parameters on the measurement results has not been thoroughly studied in the research results. In order to obtain accurate results in the process of non-contact color measurement, a method for optimizing the parameters of non-contact color measurement based on orthogonal test is proposed. The color information of standard color card Greta Macbeth ColorChecker Rendition Chart) was obtained by means of spectral radiometer Photoresearch 705 Photo Research (USA) under the condition of different parameter combination, combining with range analysis method and variance analysis method, the color information of the standard color card Gretag Macbeth ColorChecker Rendition Chart) was obtained. The experimental results show that the minimum color difference between the measured value and the standard value is 0.878 8 螖 E and the maximum value is 1.543 1 螖 E. this method can effectively select the best combination of parameters, and can analyze the influence of each parameter on the measurement results.
