摘　　要：基于蚁群优化的最大类间方差法的基本原理,分别使用该方法和迭代算法对典型的FMI成像测井图像和岩心扫描图像进行了分割,并对蚁群算法在这两类图像的分割中所产生的效果差异和原因进行了分析。实践证明,利用蚁群优化的最大类间方差法能很好地分割出包含裂缝、孔洞的FMI成像测井和岩心CT扫描的子图像,且分割效率有了一定的提高,为后续的参数定量计算打下了基础。This paper introduced the basic principles of OTSU algorithm optimized by ant colony,and the typical FMI logging image and core scan image were segmented by using this method and iterative algorithm respectively.The difference and cause of ant colony algorithm in the segmentation of these two kinds of images are analyzed.It is concluded that the OTSU algorithm optimized by ant colony can segment the sub-image of the fracture,crack and cave,and the efficiency is improved,which provides a very good foundation for the further quantitative calculation.
