摘要
通过数字图像处理技术对沥青混凝土试件的竖直及水平截面的图像进行处理,运用外接正方形方法及面积级配理论识别截面的集料颗粒粒径大小并计算截面的级配,分析计算级配与实际级配的联系,研究数字图像处理技术的有效性与可行性。
Through digital image processing technology,the vertical and horizontal section images of asphalt concrete specimens were processed. Then the particle sizes of the aggregate were identified and the gradations of section were calculated by using the method of external square and the theory of area-gradation. At last,the effectiveness and feasibility of digital image processing technology was studied in the connection of the calcu-lated gradation and the actual gradation.
