本文介绍了利用数码图像数据计算平坦金属表面彩色油污数量的方法,通过间接照明可以消除金属板表面光泽对测定结果的影响。研究结果表明:利用伽马校正可以使测定结果更加精确;洗涤试验还证实,从金属表面去除油污的过程是一级反应。
This paper introduces the method of using digital image data to calculate the amount of colored oil on the flat metal surface. The indirect illumination can eliminate the influence of the surface gloss of the metal plate on the measurement result. The results show that the gamma-correction can make the measurement more accurate. The washing test also confirms that the process of removing oil from the metal surface is a first-order reaction.
