A scanner apparatus for cased goods inspection comprising: at least one conveyor for advancing a case of goods past the scanner apparatus; at least one electromagnetic source configured to transmit a sheet of parallel propagating EM radiation illumination of predetermined width towards a vision system disposed to receive the EM radiation illumination from the at least one EM source; the vision system including a diffuser and at least one camera wherein: the diffuser is adapted to diffuse the EM radiation illumination received from the at least one EM source so that the at least one camera captures the predetermined EM radiation illumination sheet width in entirety, and the at least one camera is configured to digitize images of at least a portion of the EM radiation illumination sheet so that the case of goods advanced by the at least one conveyor through the transmitted EM radiation illumination sheet cast a shadow thereon; and a processor operably coupled to the at least one conveyor and vision system and including an image acquisition component configured to acquire the digitized images as the case of goods is advanced past the at least one camera, and an image combiner configured to selectively combine acquired digitized images into a combined image based on input beam spatial intensity reduction, that is sustained over the duration of the acquired digitized images, below a first threshold; wherein the processor is configured to determine from the combined image dimensional measurements about the case of goods including one or more of length, width, height, angle, "real box, "outside box" and "max bulge", where "real box" measurements include dimensions of a best fit shape which can be determined, or obtained from, the combined image, "outside box" measurements include dimensions of the smallest shape that contains the entire product which can be determined based on, or obtained from, the combined image, and the "max bulge" measurement is the longest dimension obtained from the case of goods being inspected. at least one conveyor for advancing a case of goods past the scanner apparatus; at least one electromagnetic source configured to transmit a sheet of parallel propagating EM radiation illumination of predetermined width towards a vision system disposed to receive the EM radiation illumination from the at least one EM source; the vision system including a diffuser and at least one camera wherein: the diffuser is adapted to diffuse the EM radiation illumination received from the at least one EM source so that the at least one camera captures the predetermined EM radiation illumination sheet width in entirety, and the at least one camera is configured to digitize images of at least a portion of the EM radiation illumination sheet so that the case of goods advanced by the at least one conveyor through the transmitted EM radiation illumination sheet cast a shadow thereon; and the diffuser is adapted to diffuse the EM radiation illumination received from the at least one EM source so that the at least one camera captures the predetermined EM radiation illumination sheet width in entirety, and the at least one camera is configured to digitize images of at least a portion of the EM radiation illumination sheet so that the case of goods advanced by the at least one conveyor through the transmitted EM radiation illumination sheet cast a shadow thereon; and a processor operably coupled to the at least one conveyor and vision system and including an image acquisition component configured to acquire the digitized images as the case of goods is advanced past the at least one camera, and an image combiner configured to selectively combine acquired digitized images into a combined image based on input beam spatial intensity reduction, that is sustained over the duration of the acquired digitized images, below a first threshold; an image acquisition component configured to acquire the digitized images as the case of goods is advanced past the at least one camera, and an image combiner configured to selectively combine acquired digitized images into a combined image based on input beam spatial intensity reduction, that is sustained over the duration of the acquired digitized images, below a first threshold; wherein the processor is configured to determine from the combined image dimensional measurements about the case of goods including one or more of length, width, height, angle, "real box, "outside box" and "max bulge", where "real box" measurements include dimensions of a best fit shape which can be determined, or obtained from, the combined image, "outside box" measurements include dimensions of the smallest shape that contains the entire product which can be determined based on, or obtained from, the combined image, and the "max bulge" measurement is the longest dimension obtained from the case of goods being inspected.
