Abstract

A method of using a hand held image reader comprises imaging a target, such as a package, positioned such three surfaces of the target appear in the captured image. A processor may then identify or determine from the image outer edges of the package. For instance, the processor may identify three or more outer edges. The processor may then identify or determine from the image corners of the target, corners being representative of the intersection of edges. The processor may then determine from the edges and corners dimensions of the package, such as height, width or depth.
