基于GF-1卫星数据岩性自动化识别方法试验

Identification Method of Lithology Automation Based on GF-1 Satellite Data

以青海省宗务隆地区为实验区, GF-1卫星PMS数据为数据源,重点从图像预处理、岩性标识体系建立、影像分割、影像分类等方面进行了基于面向对象的岩性自动分类方法实验,对实验结果进行了可靠性和稳定性评价。结果表明,利用高分一号卫星数据进行岩性自动化分类是可行的。

Taking Zongwulong Area in Qinghai Province as test area, GF-1 satellite PMS data as data source, we discussed the object-oriented lithology automatic classification method from the image preprocessing, lithology identification system establishment, image segmentation, image classification and so on, and evaluated the reliability and stability of the test results. The result shows that it is feasible to classify the lithology automatically with high resolution satellite data.
