Abstract:
According to the embodiments described herein, a method for vehicle positioning or navigation utilizing associated feature pairs may include creating a plurality of associated feature pairs by retrieving an initial set of camera data from the camera comprising two-dimensional UV space information, forming pairs from the UV space information, and associating each pair from the UV space information with pairs from each of the plurality of three-dimensional global feature points of the industrial facility map, calculating a best estimate poses from calculated vehicle poses of the associated feature pairs, using an accumulated odometry to update the best estimate pose to a current localized position and setting a seed position as the current localized position. The navigation of the materials handling vehicle is tracked and/or navigated along the inventory transit surface navigate in at least a partially automated manner utilizing the current localized position.

Claim (Index 9):
A system comprising a materials handling vehicle and a management server, wherein:\n the materials handling vehicle comprises a camera, one or more vehicular processors, a drive mechanism configured to move the materials handling vehicle along an inventory transit surface, a materials handling mechanism configured to store and retrieve goods in a storage bay of an industrial facility, and vehicle control architecture in communication with the drive and materials handling mechanisms; the camera is communicatively coupled to the one or more vehicular processors and the management server and captures an input image of overhead features; the one or more vehicular processors are communicatively coupled to the management server; an industrial facility map stored on the management server is communicatively coupled to the one or more vehicular processors, wherein the industrial facility map comprises a plurality of three-dimensional global feature points associated with a mapping of the overhead features; and the one or more vehicular processors of the materials handling vehicle executes vehicle functions to:\n (i) create a plurality of associated feature pairs by retrieving a set of camera data from the camera comprising two-dimensional UV space information, forming pairs from the UV space information, and mapping pairs from the UV space information with pairs from the plurality of three-dimensional global feature points of the industrial facility map; \n (ii) calculate respective vehicle poses for associated feature pairs within a visual range of the camera; \n (iii) calculate a best estimate pose of the materials handling vehicle from the calculated vehicle poses based on a highest-ranked pair of the plurality of associated feature pairs, wherein the highest-ranked pair comprises a smallest post sum error of the plurality of associated feature pairs; and \n (iv) navigate the materials handling vehicle utilizing the best estimate pose.
