摘要
本文介绍了基于NCS色系的嵌入式测色仪的开发过程,重点讨论了测色仪探测头结构设计对测量性能的影响,通过应用嵌入式硬件及软件技术,增强了仪器的人机交互性且大大缩小了仪器的体积,提高了便携性。系统采用ARM处理器的32位单片机,软件运行在uC/OS操作系统上。实现了标准色度显示:NCS、CIE-L*a*b*、XYZ、RGB、CMYK;色彩系统转换:CIE-L*a*b*、XYZ、sRGB、NCS系统、Munsell系统;提供两色对比,色差值显示和色差倾向提示报告等功能。
A system design of embedded color measurement instrument based on NCS color system is introduced.The design of the optical measurement part is crucial for the instrument,so we discuss its design and feature detailedly.By means of the embedded hardware and software technology,the instrument is compact and carried easily.A ARM MCU is adopted in this system.Application software runs on uC/OS;The system supplies many functions such as ：NCS,CIE-LAB,XYZ,RGB,CMYK code displaying and converting reciprocally.
