PATHWAY BOUNDARIES

A navigation system for a host vehicle may generate an image input based on at least one image captured by the camera onboard the host vehicle; provide the image input to a trained model configured to generate, based on the image input, an output identifying a left side boundary of a lane of travel for the host vehicle relative to a road surface and a right side boundary of the lane of travel for the host vehicle relative to the road surface; determine, based on the output generated by the trained model, a first location information for the left side boundary and a second location information for the right side boundary; determine at least one navigational action for the host vehicle based on at least one of the first location information or the second location information; and cause the host vehicle to implement the at least one navigational action.
