【摘要】：针对目前缺少将线性体提取技术与核密度分析二者通过计算机自动识别结合在一起的方法,提出了一种基于线性构造的核密度分析的划分岩浆岩体的方法。方法采用了形态学重构的思想对遥感影像进行了预处理,运用Canny算子对影像进行边缘提取,运用Hough变换提取二值图像中线性体信息,同时对提取的线性体进行走向-长度分析和核密度分析,最终得到岩浆岩体分解图。该方法在新疆维吾尔自治区岩浆岩体分解上取得较好的成果,实现了在岩浆岩体分解上的计算机自动识别提取。
[Abstract]:In view of the lack of combining linear volume extraction technique with nuclear density analysis by computer automatic identification, a method of dividing magmatic rock body based on linear structure nuclear density analysis is proposed in this paper. Methods the idea of morphological reconstruction was used to preprocess the remote sensing image, Canny operator was used to extract the edge of the image, and Hough transform was used to extract the linear volume information from the binary image. At the same time, the strike-length analysis and nuclear density analysis of the extracted linear body are carried out, and finally the magmatic body decomposition map is obtained. The method has achieved good results in the decomposition of magmatic rocks in Xinjiang Uygur Autonomous region and realized the automatic recognition and extraction of magmatic rock bodies by computer.
