[0022] Attached below figure 2 To further describe the present invention in detail:
[0023] The first step: preprocessing the high-resolution remote sensing image after road damage, specifically, using Gaussian filtering to remove image noise, using histogram stretching to adjust image gray contrast, etc.; and in order to use GIS road data to guide image processing, The image data to be processed is spatially registered with the data of the GIS road database.
[0024] The second step: extraction of road coverage before road damage occurs. In the high-resolution images after the disaster, the edges of the undamaged road retain the morphological characteristics of the road before the damage, and the GIS basic road data provides information such as the centerline and width of the road before the damage, and road grade. Therefore, by detecting and connecting the undamaged road edges in the image, the complete bilateral line of the road before the damage can be extracted to obtain th...
