Instrument cluster elements have to be security-critical and display legally required notifications reliably in all languages. The task was the design of an automation process to test actually displayed graphic elements.

Content:

Automated test stand for different ECUs
Installation of mechanical test setup
Automatically generate more than 100 different information and warning notifications
Image capture with frame grabber and cameras

Instrument cluster
Central display (for further information)

Image recognition with OCR algorithms for

Over 40 languages, including Asian and Arabic characters
