基于纹理特征的岩屑图像识别

Identification of debris based on texture feature

岩屑是石油和地质分析重要的实物资料.在岩屑描述的过程中不同岩性主体本身的纹理各不相同,纹理差别较大的地层,可以直接通过纹理变化来判断岩性,进而确定砂泥岩百分比的变化.本文以纹理特征为基础,通过对各种岩屑对比度值的提取以及阈值的设定实现在混合岩屑中分辨出砂岩,泥岩和页岩.实验结果表明:算法有效且实用.

The debris is very important material object in oil and geological analysis. In the process of the description of the debris in all the main lithology of the texture itself is different. For some texture layers with a larger difference, one can determine lithology and identify the changes by the percentage of sandstones and mudstones through the change of the texture directly. This paper is based on texture characters. It achieves the identification of sandstone, mudstone and shale in the mixed debris by extract the contrast characteristics of each kind of debris. The result of experiment shows that the method is effective and useful.
