Abstract

System and methods used to inspect a moving web () include a plurality of image capturing devices () that image a portion of the web at an imaging area. The image data captured by each of the image capturing devices at the respective imaging areas is combined to form a virtual camera data array () that represents an alignment of the image data associated with each of the imaging areas to the corresponding physical positioning of the imaging areas relative to the web. The image output signals generated by each of the plurality of image capturing devices may be processed by a single image processor, or a number of image processors () that is less than the number of image capturing devices. The processor or processors are arranged to generate the image data forming the virtual camera array.
