摘要

procedures for the image-based classification and segmentation of land transport routes and for the provision of geo-referenced data,where computer-based measurement data (12), in particular catalyst data, are converted from parts of the Earth's surface into pixel coordinates (16) and digital images (1), in particular digital orthoimages made from aerial or satellite images (11) of the same parts of the Earth's surface;are linked and thus identified in the digital images (1) portions (6), which depict land transport routes,where all areas outside the identified portions of the image (6), which represent land transport routes, located (2, 3, 4, 5) are uniformly identified in the digital images (1), in particular rendered obscure, preferably attenuated,where computer-aided by at least one pre-trained artificial neural network the identified portions of the image (6), which depict land transport routes, are classified by image segment and thereby segmented into several segments (7, 8, 9), each segment (7, 8, 9)an exact layer of cover is assigned for a section of the road shown in the relevant segment (7, 8, 9); andcomputer-aided by the transfer of segments (7, 8, 9), in particular from segment outlines (7, 8, 9), from pixel coordinate system toWorld coordinate system geo-referenced data (10), which for each segment (7, 8, 9) contain the coordinates of the path section depicted in the respective segment and an indication of the cover layer assigned to the respective segment (7, 8, 9).
