METHODS FOR PROCESSING SPATIAL STRUCTURES IN SATELLITE IMAGES
Annotation
An algorithm for processing spatial objects with the same topological structure on satellite images is considered. The essence of the method is the identification of structures that are stable under topological deformations and distortions. The only thing that does not change when zooming and rotating the object is its shape. The topology does not account for an object coordinates but considers its structure. Experiments with images of several areas carried out using developed algorithm and software product showed that spatial features in the images are recognized with an accuracy of 93 %. According to images comparison performed with the use of three-dimensional barcodes, the topology of objects and their barcodes do not change over time and at different scales. The algorithm for matching three-dimensional barcodes avoids manual processing of images, which reduces the time for searching and matching objects from several hours to several minutes.
