The invention provides an object-oriented classification method and device based on a scale set, and relates to the technical field of remote sensing image classification, and the method comprises the steps: obtaining block image data of a to-be-classified remote sensing image, segmenting the block image data to obtain segmented image data, and enabling any two adjacent block image data to have an overlapping region; carrying out seamless splicing on the segmented image data to obtain spliced image data; performing hierarchical region merging on the spliced image data, constructing a low-layer scale set, and determining 0-level scale segmentation data in the low-layer scale set; based on 0-level scale segmentation data, constructing a high-level scale set; according to the method, the scale parameter input by the user is obtained, the to-be-classified remote sensing image is classified based on the scale parameter and the high-level scale set, the classification result is obtained, and the technical problem that an existing object-oriented classification method is low in classification precision and classification efficiency is solved.

Description

technical field [0001] The invention relates to the technical field of remote sensing image classification, in particular to an object-oriented classification method and device based on a scale set. Background technique [0002] At present, traditional remote sensing image classification mainly uses machine learning classification algorithms to classify based on pixels and objects. For pixel-based classification, compared with only using spectral information, many scholars have added data such as NDVI, NDWI index and dem to improve the accuracy of classification results. phenomenon, adjacent pixels often have hetero-spectral problems, which lead to problems such as salt and pepper noise and poor visual effects in the classification results, and the classification results are often less accurate. The basic unit of object-oriented classification processing is the image segmentation object, which can make full use of the spectral information, spatial structure, texture informa...
