Abstract: Devices, systems, and methods obtain a sequence of images, track a label-candidate area in the sequence of images, and read a value of a barcode of interest in the label-candidate area in an image in the sequence of images.

Abstract: A system and method enabling computer meshing program to generate a finite element representation of an object is shown which receives problem definition variables relevant to the desired object, calls a projection control program to generate point surface projections based on such problem definition variables, and generates a finite element representation of the object based on the point surface projections received from the projection control program. The projection control program requests a projector to perform a point surface projection with a projector, and evaluates the point surface projection with respect to the problem definition variables to determine whether the projection was successful as well as to determine the projector's projection performance. The projection control program increments a plurality of diagnostic counters on the basis of the evaluation and updates a plurality of projection control switches on the basis of the diagnostic counter values.
