ABSTRACT:
An apparatus for measuring gobs of viscous liquid in free fall from a gob feeder includes a video camera for capturing a complete two dimensional, frozen video image of a plurality of gobs positioned substantially side by side at a point in time during free fall. The frozen image is acquired via a single operation of the camera. A digitizer is provided for digitizing the video image to produce a first digitized image of at least a first gob of the plurality of gobs with n x n pixel arrays for comparison with a second digitized image of a second gob with n x n pixel arrays. An image analyzer is provided for analyzing at least the first digitized image for relatively comparing the first digitized image with the second digitized image for determining any physical differences between the first and second gobs represented by the digitized images.
