【摘要】：基于定量体视学的原理,应用数码相机和计算机图像处理软件(Image-Pro Plus),采用图像处理法测得连续级配的混合骨料,碎石,破碎卵石3种骨料的比表面积并与试验裹浆法计算的比表面积对比。结果表明:3种骨料的等价椭圆长短轴之比的平均值为1.48,椭球模型和球模型的比表面积的平均偏差为2.8%;图像处理法与试验裹浆法的偏差较小,3种骨料的平均偏差仅为4.3%,可为骨料比表面积等几何特征参数的测量提供一种快速准确的方法。
[Abstract]:Based on the principle of quantitative stereology, using digital camera and computer image processing software, image processing method is used to measure continuously graded mixed aggregate and gravel. The specific surface area of three kinds of aggregates is broken and compared with that calculated by the experimental slurry method. The results show that the average value of the ratio of the equivalent elliptical axis to the long axis of the three kinds of aggregates is 1.48, and the average specific surface area of the ellipsoid model and the spherical model is equal to that of the ellipsoid model and the spherical model. The deviation is 2.8 and the average deviation between image processing method and experimental slurry wrapping method is only 4.3, which can provide a fast and accurate method for the measurement of geometric characteristic parameters such as specific surface area of aggregate.
