Industrial image processing

The factory of the future needs concepts in which human and machine work hand in hand and the machine relieves human.

Two white circles with violet contours overlap. One circle contains the word "human", the other one the word "machine", the overlapping area the product name APAS.

Automated visual inspection has become an integral part of modern industry and thus creates the prerequisite for error-free production. Demanding surface inspections are mainly performed by humans. However, in order to detect smallest cracks, scratches or other faults on workpieces, inspectors require a lot of concentration and accuracy. It is very tiring to keep up a high performance level over a long period of time. In addition, various persons come to different test results, in particular with workpieces difficult to assess. Automated visual inspections, on the other hand, are objective and deliver consistent test results even after a long time. Automated image processing systems offer numerous advantages: they have a high performance level consisting of high speed, low error rates and high repeatability. Moreover, employees are relieved of especially strenuous and monotonous tasks. This not only improves effectiveness, but also increases productivity.

Thanks to the learning image processing, an employee who is untrained in dealing with industrial image processing systems can also show the relevant error features to the image processing system. We have taught the machines how to better implement human thinking, thereby achieving a considerable relief for the employees.

The basic idea of supporting humans in their daily work is also applied to surface, completeness, micro-crack and dimensional inspection. Thanks to learning image processing, employees can train the machine to continuously improve its performance. Training images are used to separate test items into “good” and “faulty” parts. The employee uses the APAS inspector to take pictures of several test items, and marks the “good” and “reject” areas of the sample.

The system then analyzes and records this information for future inspections. The inspection system can be retrained at any time using additional images. This enables the operator to continually improve the recognition abilities of the APAS inspector, or to adapt it to new conditions, without the need for programming expertise. With its ability to “translate” human thoughts, the machine supports its human colleagues better than ever before.

Our testing technologies

For the APAS inspector, there are different, manually exchangeable test modules. They are characterized by particularly robust 3D-imaging processes.

Deflectometry

Suitable for the automatic recognition and inspection of reflective surfaces. With this technique, even minor flaws like blemishes, deformations and scratches can be detected. Cylindrical forms can also be scanned.

Photometric stereo

Suitable for the automatic recognition and inspection of matt surfaces. In addition to minor flaws like blemishes, deformations and scratches, even microfractures in ceramic components can be reliably detected.

Spectroscopy

Suitable for robust color testing. The testing module measures the color spectrum at each point, allowing it to reliably differentiate between different colors.

Interferometry

Suitable for the high-precision measurement of surfaces. By measuring surface heights at the nanometer scale, this technique can not only detect flaws, but also measure surface coarseness and smoothness.
