Autonomous vehicles utilize sensors to determine their position on the ground. These sensors suffer from cumulative errors which cause the vehicle's position to be compromised. The present invention eliminates such error in the orthogonal axis from the direction of travel. The present invention provides a system and method for navigating an autonomous vehicle, using various overhead features. A vision subsystem comprises at least one camera pointed towards the ceiling. The camera is preferably pointed at a pitch angle of 90 degrees with respect to the vehicle, and is pointed overhead the autonomous vehicle towards the ceiling. The vision subsystem scans the ceiling features of the building the autonomous vehicle is in, and is able to self-determine which ceiling features it will utilize for navigation while minimizing drift errors, allowing the vehicle to maintain a straight path without requiring the installation of any additional infrastructure on the ceiling.
