The invention provides a processing method and device for remote sensing image extraction information, and the method comprises the steps: sequentially carrying out the binary image vectorization andmorphological processing of the remote sensing image extraction information, and carrying out the vertex thinning of a polygon vector after morphological processing; removing obtuse angles greater than a first preset threshold value and edges less than a second preset threshold value in the polygon vectors after vertex thinning to obtain polygon vectors after corner processing, performing interpolation processing on the polygon vectors after morphological processing, and performing position fitting on the polygon vectors after corner processing according to a point set of the polygon vectors,according to the set number of the main direction edges, determining the main direction edges, and adjusting the direction of the edge to be processed according to the directions of the main directionedges. According to the invention, the remote sensing image extraction information in the polygonal vector form is used as the input of processing, so that the input is simpler, the processing efficiency of the remote sensing image extraction information is improved, more comprehensive ground object information can be considered, and the accuracy of remote sensing image extraction information processing is improved.
Description
technical field [0001] The invention relates to the technical field of remote sensing image processing, in particular to a processing method and device for extracting information from remote sensing images. Background technique [0002] Geographic information extraction based on remote sensing images is an important content in the field of remote sensing image processing, which can provide basic geographic information for all aspects of social production and life. In recent years, with the increasing demand for basic geographic information of remote sensing images, the information extraction results of remote sensing images, as an important content of basic geographic information of remote sensing images, have received more and more attention. However, there are problems such as noise and irregular boundaries in the initial extraction results of remote sensing image information. Therefore, the processing operation of the initial extraction results of remote sensing image inf...
