Abstract: Methods and system for compensating for vehicle system errors. A virtual camera is added to vehicle sensor configurations and a coordinate transformation process which attempts to match multiple 3D points associated with a landmark to a detected landmark. The virtual camera is associated with the detected landmark. The 3D world coordinate points may be transformed to a real 3D camera coordinate system and then to a virtual 3D camera coordinate system. The 3D points in real and virtual camera coordinate frames are projected onto the corresponding 2D image pixel coordinates, respectively. Inclusion of the virtual camera in the coordinate transformation process presents a 3D to 2D point corresponding problem which may be resolved using camera pose estimation algorithms. An offset compensation transformation matrix may be determined which accounts for errors contributed by mis-calibrated vehicle sensors or systems and applied to all data prior to use by the vehicle control systems.

Abstract: Methods and systems for decision making in an autonomous vehicle (AV) are described. A probabilistic explorer reduces the breadth and depth of the potentially infinite actions being explored allowing for an accurate prediction on a future scene to a defined time horizon and an appropriate selection of a goal state anywhere within that time horizon. The probabilistic explorer uses a neural network (NN) to suggest best (probabilistically speaking) actions for the AV and scene values, and a modified Monte Carlo Tree Search to identify a sequence of actions, where exploration is guided by the NN. The probabilistic explorer processes the suggested actions and driving scene(s) to provide estimated trajectories of all scene actors and an estimated trajectory for the AV at every time step for every action explored. A virtual driving scene is generated, which is iteratively processed to determine a vehicle goal state or vehicle low-level control actions.
