摘　　要：隐伏地质构造中蕴含着较多的矿产资源,是现今地质研究领域的关键所在。由于隐伏地质构造位置较深,再加之信号传输衰减、环境、光线等因素的影响,致使隐伏地质构造三维图像复杂度较高,无法获取精准的隐伏地质构造信息。本文提出基于改进FCM聚类算法的隐伏地质构造三维图像分割方法研究,归一化处理三维图像,应用拉普拉斯算子去除三维图像曲面噪声信息,提升三维图像信噪比与清晰度,基于分形维数理论定位目标隐伏地质构造,采用自适应邻域加权改进FCM聚类算法,基于改进FCM聚类算法制定三维图像分割程序,执行制定程序即可实现隐伏地质构造三维图像的分割。实验数据显示:应用提出方法获得的三维图像分割精度最大值达到了96.32%,充分证实了提出方法三维图像分割效果更好。Hidden geological structure contains more mineral resources,which is the key in the current geological research field.Due to the deep location of the hidden geological structure and the influence of signal transmission attenuation,environment,light and other factors,the 3D image of the hidden geological structure has a high complexity,which makes it impossible to obtain accurate information of the hidden geological structure.A study on the segmentation method of the 3D image of the hidden geological structure based on the improved FCM clustering algorithm is proposed.Normalize the 3D image,apply Laplace operator to remove the surface noise information of the 3D image,improve the signal-to-noise ratio and clarity of the 3D image,locate the hidden geological structure of the target based on the fractal dimension theory,use adaptive neighborhood weighting to improve FCM clustering algorithm,develop a 3D image segmentation program based on the improved FCM clustering algorithm,and implement the developed program to achieve the segmentation of the 3D image of the hidden geological structure.The experimental data show that the maximum accuracy of 3D image segmentation obtained by the proposed method reaches 96.32%,which fully proves that the proposed method has better 3D image segmentation effect.
