METHOD OF PROCESSING SCAN IMAGES Russian patent published in 2023 - IPC G06T7/30 G01C11/10 

FIELD: photogrammetry.

SUBSTANCE: invention relates to methods for photogrammetric processing of scanner images. In the method of processing scanner images, the image is formed in blocks with a width of one pixel. The complete image is obtained by adding blocks with subsequent transformation of scanner images. Then a link is established between the pixel coordinates of the scanner and transformed images, and the intensity values of the scanner image pixels are copied into the transformed image. The intensity values of the missing pixels in the transformed image are determined by interpolation. One transformed image is formed from several scanner images, for each of which an artifact map is created with information about missing and filled pixels in the corresponding sections of the transformed image. For each currently processed scanner image, the pixel intensity values are copied into the transformed image taking into account the artifact map of the previous processed scanner image. If the calculated pixel coordinates for the current and previous processed scanner images in the transformed image coincide, the pixel intensity values of the current scanner image are not copied into the transformed image.

EFFECT: eliminating distortions in the image and, as a result, increasing the information content due to the correct determination of the intensity values of the missing pixels in the transformed image.
