Abstract: Systems and methods for localization are provided. In one aspect, a LIDAR scan is captured from above to generate a point cloud. One or more locations may be sampled in the point cloud and LIDAR scans may be simulated at each location. The sampled locations and associated simulated LIDAR scans may be used to train a regressor to localize vehicles in the environment that are at poses different from the pose from which the LIDAR point cloud was captured. In one aspect, a mapping UAV systematically scans an environment with a camera to generate a plurality of map images. The map images are stitched together into an orthographic image.
