METHOD AND PROCESSOR FOR CLASSIFICATION OF POINTS ON BOUNDARY OF POLYGONAL SECTION Russian patent published in 2025 - IPC G06T15/30 

FIELD: physics.

SUBSTANCE: group of inventions relates to image processing. Method of classifying points of boundary of a polygonal portion of an object on an image of a neighbourhood map includes obtaining image data for a training area comprising a training object, generating a segmentation map containing a plurality of points based on the image data and determining the training boundary of the polygonal section. Plurality of points is associated with a feature vector formed by the segmentation model. Method includes obtaining the actual boundary of the polygonal section, determining the deviation of the position from the nearest edge from the sequence of edges indicating the mark of the boundary point, and training the second model. Training iteration includes use of a feature vector associated with a boundary point and a set of adjacent point feature vectors to generate a predicted estimate of the position of the boundary point, as well as adjusting the second model based on the result of comparing the predicted estimate and the mark.

EFFECT: high accuracy of navigation and safety of controlling autonomous vehicles.
