    摘要:

    基于岩石颜色描述特点,通过阐述颜色测量的基本原理、相关色度学内容及石油地质岩石颜色标准。研究设计以TCS230颜色传感器为基础,选用C照明体提供标准照明光源,及单片机为CY7C68013A主控芯片的控制器系统;采用漫反射积分球为几何观测条件,进行光电积分式测量和光电信号转换获取颜色信息,对RGB色彩空间与孟塞尔颜色系统进行转换后,将色样投影到RGB色彩空间上得到近似均匀划分的mRGB色彩空间,最终按照石油地质岩石颜色标准输出的颜色定量测量系统。最终实现岩石颜色从定性到半定量分析,精确的颜色描述可以反映主要矿物类型和沉积环境,对野外地质工作具有重要的指导意义。

    Abstract:

    Based on color measurement and description characteristics of the rock, the research expounds basic principle of color measurement, related colorimetry content and color standard of petroleum geology rock. To complete photoelectric integral measurement and optical-to-electric signal conversion , this study based on TCS230 color sensor constructs a device of a rock color quantitative measurement system which adopts C standard illumination light source, the main controller system with MCU CY7C68013A master chip and related display unit as the main hardware, with geometry observation condition of diffuse reflectance integrating sphere ,the RGB color space and the Munsell color system are converted through CIE- XYZ coordinate system, then the Munsell color samples is projected onto the RGB color space to obtain mRGB color space with approximate uniformly divided. Finally, a quantitative measurement system according to the color standard of petroleum geology rock can be obtained. Finally, accurate color description with the analysis of rock color from qualitative to semi quantitative can reflect the main mineral types and sedimentary environment, which has important directive significance in the field geological work.
