摘要:本文主要研究用分线法和三角愣柱法两种方法来计算图像的分形文数 ,并对两种方法的算法进行了简单的阐述和比较,得出不同地物的分形文数D值不同和同一地物在不同波段分形文数D值存在差异的结论。也就是说自然界地物的自相似性只存在一定的观察范围之内.,然物体仅仅是统计上的自相似而已,并不是完全的自相似。本文选取了两个比较典型的地物来研究:山区和湖泊.39584 毕业论文关键词:遥感地物 ;分形文数;分线法;三角棱柱法; 山区; 湖泊
The Fractal Measurement of Remote Sensing features
Abstract:With the development of remote sensing technology,fractal theory which is combined with remote sensing application has become a hotspot ,it is a new technology to solve the problems of remote sensing application by means of handling remote sensing image data and measuring ground object. In this paper, line-pider and triangle prim method are discussed to calculate the fractal dimension , at the same time , the algorithm of the two method is simply described and compared, we draw a conclusion that different features have different fractal dimension D value and the same object has different fractal dimension D value in different wave band. In other words, the self-similarity of ground feature is meaningful in a specific range, and object is just a statistical self-similar, not the fully self-similar. We research two typical features: coteau and lake.
Key words: fractal dimension; line-pider method; triangle prim method; coteau; lake
