Abstract

The invention provides a remote sensing information sample selection method and system. The method comprises the following steps: acquiring a high-spatial-resolution fine correction satellite image, high-temporal-resolution vegetation index cube data and a sampling area map; acquiring a plurality of image areas in the sampling area map, wherein the image areas comprise a first image area and a second image area; obtaining a reference sample point and an identification tag corresponding to the reference sample point; and classifying the second image area based on a classification model, the classification model being obtained after training based on the reference sample point and an identification tag corresponding to the reference sample point, and the identification tag being predetermined according to the sample type. According to the remote sensing information sample selection method and system provided by the invention, the precision and reliability of sample selection and the sample selection efficiency can be improved.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a method and system for selecting remote sensing information samples. Background technique [0002] At present, in the field of remote sensing and earth observation intelligent recognition, due to the extreme complexity and regional heterogeneity of the earth's surface, there is no general classification sample library of land cover types. Practitioners and researchers of remote sensing and earth observation intelligent identification need to build a sufficient and reliable sample library for specific research objectives before conducting intelligent identification research. The general approach is to use sub-meter-level high-spatial-resolution images with high recognition of the surface, and it will take a long time for professionals with rich experience in remote sensing interpretation to carry out sample selection. [0003] Moreover, in the process of manually selecting sam...
