Abstract
A method of inspecting cased goods includes advancing at least one case of goods on a conveyor, generating an illumination sheet of parallel illuminating rays with at least one electromagnetic source, and capturing an image, formed by the illumination sheet passing through a diffuser with at least one camera located so as to capture illumination from diffused parallel rays of the light sheet, where the image case embodies a goods image that is generated by the case goods moving between the light source and the at least one camera, where part of the parallel sheet of light is at least partially blocked by the case of goods, thus generating a gray level image.
