基于颜色匹配的人眼视觉误差测试实验仪研究

摘要

根据格拉斯曼混合定律,采用新型的LED光源,运用ATMEGA16单片机,设计制造一款RGB颜色匹配仪,并通过此仪器测试人眼视觉色度误差的大小.将人眼通过RGB颜色匹配仪观察到的匹配现象通过CCD成像,结合MATLAB进行图像处理,得到人眼对绿色光、蓝色光、红色光的视觉误差分别为0.0118、0.0706、0.2329,即蓝、绿色光视觉误差较小,红色光较大.%According to the Grassman, adopt the source of LED, use the ATMEGA16 microcontroller, design a RGB matching instrument, and by the size of this device to test human visual error.human eyes through the RGB color matching instrument observed mismatch by CCD imaging, combined with MATLAB for image processing, get the human' s eyes to green light, blue light and red light visual error are 0.0118, 0.0706, and 0.2329, indicating that the green light and blue light human visual error is small, red light human visual error is bigger.
