Beschreibung
Zusammenfassung:	A digital measurement system for making linear measurements of ground cannulae comprises a mounting device for positioning a manufactured cannula sample in a predetermined orientation; a camera device for producing an analog photographic image of a cannula sample; a digitizer device for receiving the photographic image and converting the image into digital encoded image data; and a control device for processing the digital data to locate one or more critical point locations of the cannula, the control means further processing the one or more critical point locations to thereby obtain the cannula dimensions in real time.
