Abstract:
As an autonomous vehicle moves through a local area, pairwise alignment may be performed to calculate changes in the pose of the vehicle between different points in time. The vehicle comprises an imaging system configured to capture image frames depicting a portion of the surrounding area. Features are identified from the captured image frames, and a 3-D location is determined for each identified feature. The features of different image frames corresponding to different points in time are analyzed to determine a transformation in the pose of the vehicle during the time period between the image frames. The determined poses of the vehicle are used to generate an HD map of the local area.

Claim (Index 4):
The method of  claim 1 , wherein determining the transformation between the first and second positions further comprises:\n for each of a plurality of iterations:\n selecting a different first subset of features of the first image frame; \n identifying the second subset of features of the second image frame corresponding to the selected first subset of features; \n determining a candidate transformation between the determined positions of corresponding features of the first and second subsets of features; \n for each feature of first image frame, matching the feature with a feature of the second image frame, based upon applying the determined candidate transformation to the feature to generate a transformed feature; and \n determining a metric for the determined candidate transformation, based upon the features of the first image frame and their determined matching features of the second image frame; and \n selecting a candidate transformation of the plurality of iterations having a highest metric.
