Abstract
Disclosed in the present disclosure is a method for processing remote sensing images by fusing elevation information. The method includes the steps: acquiring an image data set, and preprocessing the image data set to obtain an image set; performing simple linear iterative clustering (SLIC) segmentation processing on the image set, introducing elevation information through weighting and setting a threshold in the SLIC segmentation processing process to obtain pre-segmentation results; updating a neighborhood relationship among clusters on the basis of the pre-segmentation results by using a data structure of a neighborhood array, and establishing a comprehensive similarity criterion of weighting combined with elevation features; and finally, for ground objects with complex elevation, setting determination conditions before merging according to elevation differences between adjacent clusters, and performing region merging by setting weight coefficients of different sizes in comprehensive similarity indexes according to determination results to complete image processing.
