    Abstract: The present method relates to navigation aids for highly automated autonomous vehicles (AV). According to the proposed terrain mapping method for AVs, a global terrain map is generated, which is divided into cells; said map is recorded in the memory of a mapping module of an AV on-board computer; said mapping module receives a stream of images from a camera mounted on the AV; the received images are processed and linear roadway objects are detected; a map of features of the detected linear roadway objects is generated; a local map (1) is generated, which is divided into cells; to account for errors in the detection of linear roadway objects (2), initial probability estimates for the presence of features of detected linear roadway objects in cells of the global map and of the local map are determined, wherein the probability estimate for the cells of the global map is an a priori estimate; the features of detected linear roadway objects are recorded in the corresponding cells of the global and local maps; a final map of the roadway (3) is obtained by binarizing the cells of the obtained map using a threshold value for the probability estimate for the presence of a feature of a detected linear roadway object.
