| titleOfInvention | A method and system for detecting changes in spatial information |
| abstract | The present invention provides a spatial information change detection method and system, wherein the method includes: obtaining first time-phase spatial information data and a second time-phase image set; performing extreme value synthesis on the second time-phase image set to construct a foundation Spatial feature library; based on the first time-phase spatial information data, perform incremental image segmentation on the second time-phase image set to obtain a patchy-like sample set; build a basic spatial feature library to obtain the first basic spatial feature; obtain the image-like patchwork Calculate the degree of association between the first and second land classes in the class sample set on the first basic spatial feature, and use the first basic spatial feature as the first optimal spatial feature when the conditions are met; Optimal spatial feature library; determine the distinguishing thresholds of different land type features in the optimal spatial feature library in the sample set of image spots, extract the changed image spots, and perform change detection. |
