Patent Images

1. A method comprising:

  • determining an observed position and an observed pose of a vehicle;

    generating a reference image based on the observed position and observed pose, wherein (a) the reference image comprises one or more reference static features and (b) the reference image is generated from the perspective of the observed position and the observed pose;

    implicitly comparing the reference image to a captured image using a pose error network to determine a misalignment between at least one feature of the reference image and a corresponding feature of the captured image, wherein the pose error network comprises a trained neural network; and

    based on the determined misalignment, determining, by the pose error network, a correction to the observed position, the observed pose, or both.
