LOAD TRACKING UTILIZING LOAD IDENTIFYING INDICIA AND SPATIAL DISCRIMINATION

摘要

Methods and apparatus for determining the location of one or more unit loads in a coordinate space in a facility, comprising an integrated system that identifies a load by reading indicia on the load, determines the position of the indicia in the coordinate space, and stores the indicia position and load identity in a Label Map. A mobile subsystem on each conveying vehicle identifies the location and orientation of that vehicle using a position/orientation sensor, determines the identity of the load, establishes a Target Cube to discriminate the desired load from nearby loads, confirms acquisition of the load, and communicates the information to a fixed-base subsystem. Load identity and the location and orientation of the vehicle when a load is deposited are used to create a Load Map that contains the identity, position and orientation of all identified loads in the coordinate space.
