Print inspection with Common Vision Blox
Materials such as paper, glass or steel often undergo inspection - sometimes at very high speeds - in order to detect defects and assign pre-defined quality classes to them.
Solutions with CVB Print Inspection tools
Inspect security prints
It is no easy task to examine the quality of security features on bank notes and credit cards. In addition to holograms watermarks, security threads or infrared features must be checked thoroughly. We offer special CVB tools to respond to these challenges:
Recognise even the most complex patterns for example on bank notes at extremely high scanning speeds – even in case of object rotation or scaling. The printing of credit cards is a highly demanding task. But CVB Minos is equipped to cope with the challenges thanks to its ability to distinguish between two similar objects and patterns with varying backgrounds.
Identify and verify the most diverse codes on your products. The algorithm locates the codes automatically, regardless of position or rotation. Poor contrast, uneven surfaces or other interfered environments do not pose any problem for this powerful machine vision tool. Needless to say, the software is also able to check the code quality.
Flexible print and pattern inspection
In many industries silk screen printing is used on flexible and varying surfaces such as glass, ceramics or textiles. The reliable inspection of these products and their variations can only be achieved with highly complex algorithms.
CVB Flex Inspect is the perfect solution for this kind of applications. Rather than using a single golden template, CVB Flex Inspect uses the latest in machine learning research to build a complex appearance model of good examples that is then applied to the inspected part to give a difference image. In this way „natural“ variations can be better detected and the rate of false alarms can be significantly reduced.
Inspect print that varies
In mechanical engineering machine vision hits boundaries when it comes to reading printed or punched characters. In many cases the charaters are difficult to read or show different heights or depths. The versatile CVB Manto software allows you to solve this challenging task.
Note: CVB Manto cannot be over trained - the more examples you give, the better the recognition.
