Embodiment Construction
[0050] The technical solution of the present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.
[0051] The present invention proposes to create sampling points on the terrain surface in a three-dimensional scene, obtain three-dimensional scattered points containing slope distribution information in the region by calculating the slope based on the elevation values of adjacent points, and then divide the scattered points into scales to obtain different scales Scattered point collection, after multi-fractal feature inspection, multi-fractal calculation, multi-fractal spectrum drawing and other processes, the multi-fractal spectrum and multi-fractal characteristic parameters can be obtained, and then the empirical model can be established.
[0052] see figure 1 , a method for multifractal quantification of terrain complexity in a three-dimensional scene provided by an embodiment of the present invention, comprising the fo...
