METHOD AND SYSTEM FOR NAVIGATING AUTONOMOUS GROUND VEHICLE USING RADIO SIGNAL AND VISION SENSOR

Abstract:

The present invention discloses a method and a system for navigating an Autonomous Ground Vehicle (AGV) using radio signal and vision sensor. The method comprising generating a trajectory plan for a short distance from a path plan, wherein the path plan is determined using destination location and AVG location, identifying an approximate AGV location using a radio signal-based trilateration mechanism, estimating AGV location error with respect to a road lane centre by determining distance from the approximate AGV location to road boundary and road lane marking line and orientation difference between AGV orientation and road orientation, and correcting the trajectory plan by using the estimated AGV location error for navigating an AGV.
