High demands on products as well as high time and cost pressure are decisive competitive factors across all industries and sectors. Whether in the food or automotive industry quality, safety and speed are today more than ever before factors that determine the success of a company.
Zero-defect production is the goal. But how can it be guaranteed that only flawless products leave the production line? How can faulty quality decisions, which lead to high costs, be avoided? In order to test this reliably, a wide variety of methods are used in quality assurance.
In order to make quality inspection as efficient, simple, reliable and cost-effective as possible, German company sentin develops solutions that use deep learning and industrial cameras from IDS to enable fast and robust error detection.
A sentin VISION system uses AI-based recognition software and can be trained using a few sample images. Together with a GigE Vision CMOS industrial camera from IDS and an evaluation unit, it can be easily embedded in existing processes.
A visual inspection with the human eye is possible, but it can be error-prone and expensive: as tiredness is a factor, while working time is costly. A mechanical test, on the other hand, is usually accompanied by complex calibration, i.e. setting up and adjusting all parameters of both software and hardware in order to detect every error. In addition, product or material changes require recalibration. Furthermore, with the classic, rule-based approach, a programmer or image processor must program rules specifically for the system to explain to the system how to detect the errors. This is complex and with a very high variance of errors often a hardly solvable Herculean task. All this can cost disproportionately much time and money.
sentin and the IDS industrial cameras develop solutions that enable fast and robust error detection. This is because, in contrast to conventional image processing, a neural network learns to recognise the features on the basis of images themselves.
