Abstract
Various aspects of the present disclosure generally relate to autonomous driving and driver assistance systems. In some aspects, a device associated with an ego vehicle may obtain a series of images that depict a reference vehicle traveling along a road segment ahead of the ego vehicle. The device may estimate, based on the series of images, a size of the reference vehicle and/or a position of the reference vehicle relative to the ego vehicle. The device may track a trajectory of the reference vehicle along the road segment ahead of the ego vehicle based on the estimated size of the reference vehicle and/or the estimated position of the reference vehicle over the series of images. The device may estimate a surface geometry associated with the road segment ahead of the ego vehicle based on the tracked trajectory of the reference vehicle. Numerous other aspects are described.
