在这项工作中，不同的方法来获得粉末浓度的校准曲线，从数字图像的散装材料进行审查和比较。它示出在这里，床图像的灰度值和粉末体积分数之间的对数关系产生高质量的校准曲线，而不需要拟合常数。这一结论对我们的实验数据和其他先前发表的使用多项式方程定义校准曲线的数据都是有效的。(C)2001 Elsevier Science S.A. All rights reserved.
In this work, different approaches to obtain calibration curves of powder concentration from digital images of bulk materials are reviewed and compared. It is shown here that a logarithmic relation between the grey scale values of the bed images and the powder volume fraction produces a high quality calibration curve without the need of fitting constants. This conclusion is valid both for our experimental data and other previously published that have used polynomial equations to define calibration curves. (C) 2001 Elsevier Science S.A.
