摘要
物质溶液的浓度和其颜色读数之间存在着密切联系。根据常识得知,R、G、B三个维度即可确定一种颜色,将颜色用6位的16进制数表示,然后将16进制数转换成10进制,经过尝试得到了拟合效果最好的(浓度与R、G、B值之间的)六次多项式模型,从拟合效果图和误差分析中可以看出,回归效果较好。
There is a close relationship between the concentration of substance solution and its color reading.According to common knowledge,R,G and B dimensions can determine a color.The color is represented by 6-bit hexadecimal number,and then the hexadecimal number is converted to 10-bit.After trying to get the best fitting effect(between the concentration and R,G,B values),the six-order polynomial model is obtained.From the fitting results,the regression effect is good.
