METHOD FOR MAPPING OF AREA FOR AUTONOMOUS VEHICLES Russian patent published in 2022 - IPC G06V20/56 G06V10/22 G01S13/89 

FIELD: car industry.

SUBSTANCE: invention relates to methods for mapping of an area for autonomous vehicles (hereinafter – AV). A global area map is formed and saved, images received from AV cameras are processed with isolation of linear objects of a roadbed, a map of signs of isolated objects is formed, a local map is formed, initial assessments of the probability of finding signs of isolated objects in global and local map cells are set, signs of isolated objects are recorded in corresponding global and local map cells, based on the specified points, lines are formed, for each local map cell, the probability of finding a sign of an isolated object of the roadbed is assessed, the resulting section of the local map is applied to a corresponding section of the global map with summation of assessments of the probability of finding a sign of an isolated object, taking into account the previous assessment, the resulting map is obtained by binarization of the resulting map cells by a threshold value of the assessment of the probability of finding a sign of an isolated object of the roadbed.

EFFECT: increase in the accuracy of mapping for AV.
