1. A materials handling vehicle comprising 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, wherein: the camera is communicatively coupled to the vehicular processor(s) and captures an input image of overhead features; an industrial facility map comprises a plurality of three-dimensional overhead global feature points associated with a mapping of the overhead features; and the vehicular processor(s) of the materials handling vehicle executes vehicle functions to: (i) create a plurality of overhead associated feature pairs by: retrieving an initial input image comprising overhead features from the camera comprising two-dimensional UV space information wherein U and V each correspond to a dimension in a two-dimensional space; forming a plurality of overhead feature pairs by pairing points from the overhead features in the two-dimensional UV space information in the input image; and associating the plurality of overhead feature pairs from the two-dimensional UV space information with overhead global feature point pairs formed from pairing the plurality of three-dimensional overhead global feature points of the industrial facility map, wherein a first overhead feature pair of the plurality of overhead feature pairs from the two-dimensional UV space information is associated with a first overhead global feature point pair formed from pairing a first pair of three-dimensional overhead global feature points such that the first overhead feature pair is associated with the first overhead global feature point pair to form a first overhead associated feature pair of the plurality of overhead associated feature pairs; (ii) calculate a vehicle pose from the each of the plurality of overhead associated feature pairs within a visual range of the camera; (iii) calculate a best estimate pose of the materials handling vehicle based on a highest match-rated pair of the plurality of overhead associated feature pairs by ranking matches between the plurality of overhead feature pairs from the two-dimensional UV space information and corresponding overhead global feature point pairs formed from the industrial facility map; (iv) use an accumulated odometry of the materials handling vehicle to update the best estimate pose to a current localized position of the materials handling vehicle; and (v) utilize the current localized position to: track the navigation of the materials handling vehicle along the inventory transit surface, or navigate the materials handling vehicle along the inventory transit surface in at least a partially automated manner, or both.
