Embodiment Construction
[0034] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.
[0035] First, collect low-spatial-resolution remote sensing images and high-spatial-resolution surface classification maps of the same area and the same range, and use these two images as known data;
[0036] Then, for each band of the remote sensing image with low spatial resolution, traverse each pixel on it, and process each pixel as follows:
[0037] The first step is to count the components and their abundances within the spatial scope of the mixed pixel (the component is the category in the surface classification map, and the abundance is the proportion of the component to the area of the pixel), referring to the mixed image The number of components in the unit to establish the initial window scale (formula such as: S is the window scale,...
