Abstract
Systems and methods are disclosed herein for performing unstructured lane estimation. In one example, unstructured lane estimation involves the steps of receiving an overhead representation of a region and a rasterized trace generated from sensors of a vehicle traveling in the region and outputting, using a machine learning model, probabilities that neighboring pixels of pixels forming the rasterized trace is part of a lane based on the overhead representation and the rasterized trace.
