1. A method of quality control inspection of louvers formed by a louver perforation system, the method comprising:
receiving data corresponding to a pipe length and a number of perforations to form along the pipe length;
receiving data corresponding to an upper and lower blade size threshold of a louver blade portion of a perforation of the perforations to form along the pipe length;
receiving data corresponding to a maximum count of broken perforations of the perforations to form along the pipe length;
receiving data corresponding to an upper and lower opening size threshold corresponding to an opening portion of the perforation of the perforations to form along the pipe length;
forming, by the louver perforation system, a plurality of perforations along the pipe length;
collecting, by a 3D camera, an image of the perforations of the plurality of perforations during the forming;
processing the image to measure, by a controller, a blade size of the louver blade portion;
processing the image to measure, by the controller, an opening size of the opening portion of the perforation;
determining, by the controller, whether the louver blade portion of the perforation is broken and updating a count of broken perforations in response to the determining;
computing a rolling average of at least one of the blade size or the opening size; and
displaying, on a display terminal, a graph of the rolling average.
