What Does Our Technology Accomplish?

Defis Inspection System consists of a hardware unit, the control software, an interface module and the inspection module. Due to our open data structure, inspection results can be processed either through our interface module or by a third party control software. Defis has been developed for the open source Linux operating system and runs on common x64 systems.

The Hardware Unit

The hardware unit consists of a individually customized camera and light combination. We provide different technologies like area scan or line scan cameras and make use of multiple light spectrums to perfectly fit your needs. Our hardware is IP67 rated for operation in harsh industrial environments. The unit is controlled via Ethernet, so that the processing of the aquired image data by the inspection software module can take place locally or remotely in a data center or even in the cloud. A local computing unit is tailored by us to your application and is delivered in 19″ server format. Depending on the requirements, web material with a width of a few cm up to 3m can be inspected.

Interface Module

The Defis Interface Module provides the control of the system via fieldbus network or a web service. Multiple protocols are available. Nagios is supported as remote monitoring software.

Inspection Module

The Defis Inspection Module is the vision component of the system. It processes the camera images and makes the decision about the occurrence of defects. The Defis model is a learning system. Which defects to detect and respective detail settings can be refined by the customer over time. New defects can be added and thresholds for exisiting ones can be adjusted anytime.
