Abstract

The invention relates to an image segmentation method and system for remote sensing image terrains. The method comprises the following steps: in step S1, remote sensing images are placed in a full convolution network which comprises a plurality of convolution layer groups, a plurality of deconvolution layers and a CRF model layer that are orderly arranged; the convolution layer groups comprise convolution layers and sparse convolution layers that are arranged alternatively; in step S2, the remote sensing images are subjected to coordinate point marking operation via the plurality of convolution layer groups and the plurality of deconvolution layers, a terrain classification probability graph is obtained, and different terrains have different coordinate point colors and coordinate point depths in the terrain classification probability graph; in step S3, all coordinate points in the terrain classification probability graph are classified according to the coordinate point colors and coordinate point depths, and segmented images of different terrains are obtained. The beneficial effects of the image segmentation method and system are that colors and depths of the remote sensing images are added in image identification and segmentation, color information and depth information are analyzed comprehensively, and images can be cut precisely via the CRF model layer.

Description

technical field [0001] The invention relates to the technical field of remote sensing image processing, in particular to an image segmentation method and system for remote sensing image ground objects. Background technique [0002] The edge segmentation of ground objects in remote sensing images is a key technology of geographic information systems, and plays a very important role in the fields of land planning, disaster prevention, unmanned aerial vehicles, satellites, unmanned ships and resource monitoring. The traditional method only considers two-dimensional data, and only considers the relationship between the coordinate point color and coordinate point position of the image in the segmentation process. For three-dimensional remote sensing images, all information cannot be effectively used for image segmentation. Contents of the invention [0003] The technical problem to be solved by the present invention is: the traditional method only considers two-dimensional data...
