The target-actual comparison is a conventional task in image processing which checks for deviations, for example in manufacturing processes. Any follow-up action as a consequence of the “pass” or “fail” result invariably leads to the sorting of the inspected object.
Control loops in connection with the introduction of objects for further processing require a readjustment of the position and occasional alignment in real-time. Decentralized image processing solutions come into play here. NET supports these inspection and control tasks with smart vision solutions.

Checking the completeness of packaging is often performed under difficult conditions, such as on reflecting packaging or extremely versatile items. The testing of seals is of key importance, particularly in the food industry. This demands a high level of precision from the optical solution. The measurement of liquid levels in mass products must be carried out within very short cycles.
Accuracy and speed are the crucial factors in pick-and-place machines. Besides 2D alignment, 3D tilt detection is also a must. This calls for a clever optical solution. The fact that parts are becoming increasingly smaller poses a particular challenge. High-resolution cameras are needed in order to recognize every single important detail. But the larger volume of data still has to be transmitted quickly. Creative approaches that lead to the desired result are needed here.
The quality of color and print on packaging and other print substrates is an important selling point. In multi-color printing, the precise vertical alignment of the registration marks is crucial – in real-time, to optimize process speeds. Color deviations in quality products, especially corporate and product brands, should be kept to a minimum. Different optical technologies are applied for round objects.
