ABSTRACT:
An apparatus for measuring gobs of viscous liquid in free-fall, comprises a video camera adapted to be focused on the path of the gobs so that the gobs fall through the field of view thereof. The video camera is equipped with an electronic shutter for capturing successive two-dimensional, high resolution, frozen video images of the path of the gobs; a digitizer for digitizing the successive images to produce n.times.n pixel arrays; and an image analyzer for identifying usable gobs in the arrays and analyzing the image in the vicinity of said gobs on a line-by-line basis to locate the edges thereof.
