摘要
利用安卓智能手机的CMOS传感器并配合安卓手机软件ColorGrab来获取不同浓度透明有色溶液的L＊、a＊、b＊值，并将相应数据导入Excel处理后得到相应的色差值，通过建立色差值与浓度之间的数值关系，再利用智能手机采集待测透明有色溶液的色差值，即可得到待测溶液的浓度。系统经过定标后测量的过程即不再需要标准溶液。
This paper got the value of L ＊ , a ＊ , b ＊ of the different concentration of transparent colored solutions by using CMOS sensor of Android smart mobile phone and Android mobile phone software Color Grab, introduced the corresponding data into Excel to get the corresponding value of chromatism, obtained the concentration of the solution by establishing the numerical relationship between value of chromatism and concentration, and measuring value of chromatism of the transparent colored solution by the smart mobile phone. After calibration, the system no longer needed standard solution.
