为了使牙齿健康美容领域中牙齿的配色更加精确,设计出一款以色度学原理为基础,应用白平衡调节手段,采用集成数字化电路及掌上结构设计的牙齿测色仪器。设备以正白光高亮LED为光源、mega128单片机为核心,采用TCS230可编程颜色传感器采集颜色信号,通过C语言编程来实现颜色数据的采集、显示以及存储。通过比色卡对比实验,分析了几种影响测量精确度的因素。仪器具有测量精度高、稳定度好、功耗低、便于携带等优点,具有广泛的应用前景及市场空间。

In order to make the results of teeth color measurement in the field of dental cosmetic more accurate, this paper has designed a color monitoring instrument, which is based on the colorimetry principle. It used the white-balance adjustment method, technology of integrated digital circuit and design of handheld structure. The source of the instrument was LED light. The core was a mega128 microcontroller. TCS230 programmable color sensor was used to gather the color signal, and C language was used to realize the collection, the storage and the display of the color data. In the experiment of comparison of the measured color with the international standard color card, we analyzed several factors, which affected the accuracy of the measurement. The instrument had a series of advantages, such as high measuring accuracy, high stability, low-power consumption and easy to carry. In short, the instrument has promising applications and broad market.
