    Abstract: Disclosed herein are methods and systems for using prior maps for estimation of lane boundaries or other features within an environment. An example method may include receiving a location of a plurality of detected points on a roadway in an environment of an autonomous vehicle, determining, from a prior map of the roadway, a location of a plurality of reference points from a boundary marker on the roadway that correspond to the detected points on the roadway, determining distances between the detected points and the corresponding reference points based on the location of the detected points in the environment and the location of the reference points from the prior map of the roadway, determining a confidence buffer representing a threshold amount of variation associated with the prior map based at least in part on the distances between the detected points and the corresponding reference points, selecting one or more of the detected points such that the distance between a selected detected point and a corresponding reference point is less than the confidence buffer, and using the selected points to direct the autonomous vehicle along the roadway.

    Abstract: Methods and systems for detecting road curbs are described herein. A vehicle's computing system may receive point clouds collected in an incremental order as the vehicle navigates a path. The point clouds may include data points representative of the vehicle's environment at a given timepoint and include associated position information indicative of the vehicle's position at the timepoint. Based on the associated position information in the point clouds, the computing system may process the point clouds into a dense point cloud representation and may determine features of the representation. The computing system may provide the features to a classification system that is configured to output an estimate of whether the features are representative of a road curb. Based on the output of the classification system, the computing system may determine whether the given data points represent one or more road curbs in the vehicle's environment.

    Abstract: Methods and systems for use of previous detections to improve lane marker detection are described. A computing device may be configured to receive lane information generated at previous time periods, and relates to detection of a lane boundary on a road of travel of a vehicle. The computing device may be configured to estimate, based on the lane information, a projection of a respective lane boundary ahead of the vehicle on the road. The computing device may further be configured to determine, based on a speed of the vehicle and geometry of the road, a level of confidence for the projection of the respective lane boundary. The computing device may also be configured to provide instructions to control the vehicle based on the projection and the level of confidence.
