Optical test station for optical testing of hollow bodies, esp. cylinders in internal combustion engines

摘要

the optical test station has an image acquisition system with a light source (7) and an image acquisition device (8) for optical detection of the inner casing surface (4) of the hollow body and an evaluation unit which communicates with the image acquisition system and contains a computer. The image acquisition device is positioned so that that its central axis (40) intersects the longitudinal axis (41) of the hollow body and the intercept point (P) of the central axis of the image acquisition device and longitudinal axis of the hollow body lies outside the hollow body's (3) inner chamber An Independent claim is also included for a method of optical testing of hollow bodies, esp. cylinders in internal combustion and use of the test station in an engine mass production line
