| 摘 要： | 采用数码相机采集图像.利用Matlab将加气混凝土砌块断面照片转化为灰度照片,并对照片进行去噪、直方图均衡化、二值化处理,采用图像分析法实现了对蒸压加气混凝土的宏观孔孔隙率、孔面积及其分布等孔结构特征的计量.分析结果表明,基于Matlab图像分析法可以对蒸压加气混凝土的孔结构进行初步的量化表征,但限于所采用数码相机的分辨率,该方法只适合表征蒸压加气混凝土中的宏观孔.通过改进程序分辨能力、相片拍摄技巧以及样品准备与处理方法可以大幅减小图像分析法的表征误差,提高方法的准确性.

| Abstract: | Autoclaved aerated concrete(AAC) cross section photograph was achieved with digital camera.Then the cross section photograph was changed to gray image with the help of Matlab.After a serial process including median filtering,histogram equalization and binary conversion,the pore structure characteristics of AAC such as porosity,pore area distribution were obtained using image analysis method.Analysis results show that the image analysis method based on Matlab can be used to characterize AAC pore structure,wh... |
