Embodiment Construction
[0034] Such as figure 1 As shown, it is a remote sensing image semantic segmentation method with multi-scale segmentation constraints involved in this embodiment, including the following steps:
[0035] Step A. The scale of the same object in remote sensing images of different resolutions will also change. Therefore, when setting scale parameters for multi-scale segmentation, it is necessary to set appropriate scale parameters for remote sensing images of different resolutions based on past experience. Including start scale, end scale, and scale interval. The starting scale generally starts from scale 10, and if the size of the ground objects in the image is large, you can start from a larger scale. The termination scale is set reasonably based on the largest feature in the image. The scale interval is generally set to 10. Then set the segmentation parameters used to measure regional homogeneity for region merging, mainly including spectral factor and shape factor, and the ...
