Abstract
According to the embodiments described herein, an industrial vehicle can include a camera and one or more processors. The camera can capture an input image of ceiling lights of the ceiling of the warehouse. The one or more processors can execute machine readable instructions to detect transversal edges from the ceiling lights of the input image. The machine readable instructions executed by the one or more processors can determine points of convergence between the transversal edges and a first edge line and a second edge line. The machine readable instructions executed by the one or more processors can select a set of point fixes from the points of convergence. The machine readable instructions executed by the one or more processors can navigate the industrial vehicle through the warehouse utilizing the centerline and the set of point fixes.
