Abstract:
Techniques and examples pertaining to vehicle odometry using one or more radars disposed on a vehicle are described. A method for radar odometry may involve receiving, by a processor from the radars, measurement data of stationary objects and moving objects that are located in an environment a vehicle is traversing. The method may also involve performing, by the processor, a random sample consensus (RANSAC) calculation to select the measurement data of the stationary objects and disregard the measurement data of the moving objects. The method may also involve calculating, by the processor, one or more dynamic variables of the vehicle based on the measurement data of the stationary objects. The proposed method processes the measurement data of the stationary objects with one single RANSAC calculation and one least squares problem solving, thereby greatly reducing computation cost and time as well as latency in operation for providing the vehicle odometry.

Claim (Index 5):
The method of  claim 1 , wherein the performing of the RANSAC calculation to identify the measurement data of the stationary objects comprises:\n calculating a plurality of representative points in a mathematical space, each of the representative points associated with respective measurement data of one of the stationary objects or moving objects as detected by one of the one or more radars; finding a best-fit plane in the mathematical space that encompasses a majority of the representative points within a predetermined threshold; identifying one or more of representative points located within the predetermined threshold from the best-fit plane as inliers; and designating a part of the measurement data associated with the inliers as the measurement data of the stationary objects.
