Abstract
A method for fitting an odometry noise model of a vehicle is described. The method includes collecting multiple passes of sensor measurements from motion sensors of the vehicle to measure a motion sensor noise during a testing operation of the vehicle. The method also includes determining an estimated standard deviation of the motion sensor noise measured during the testing operation of the vehicle. The method further includes determining the odometry noise model of the vehicle according to the estimated standard deviation of the motion sensor noise measured during the testing operation of the vehicle. The method also includes compensating, using the odometry noise model, the motion sensor noise during normal operation of the vehicle.
