摘要
摄影图像是一种应用于土的裂隙研究的较新测试手段。在数字图像的获取与处理过程中,影响裂隙特征定量化分析处理效果的因素有很多。结合膨胀土裂隙图像处理中遇到的问题,分析了图像采集时的光源、图像的像素、图像处理过程中阈值选择等因素对图像处理结果的影响,提出了合理选择上述方法或参数的建议,结果可供相关研究工作参考。
The photographic image is a new method for study soil crack.There are many factors that affect the quantitative analysis of crack characteristics in the data acquisition and processing of the digital image.Common problems encountered in the expansive soil analysis are explored.The effect of factors,such as,light source,resolution of the image and threshold values in the digital processing,on the digital processing are discussed and improving suggestions are proposed in the paper.
