The instrument for flat objects geometry inspection allows to identify and measure geometrical parameters of transparent and non-transparent objects, such as:
The unit operation is based on a through-transmission measuring method. Diffused light source illuminates the object boundary for the high-resolution camera with the installed telecentric lens, that allows to eliminate prospective distortions (the image dimensions remain the same at any distance from the lens to the inspected object).
The object image is processed by means of a special software complex, that allows to carry out the following measurements, based on the image decomposition to simple geometric elements:
Geometrical parameters monitoring is based on comparison of received image with the user's drawing (in case of complex objects inspection), or with the tolerances table (in case of the rings inspection and other simple shaped objects).
