Audi plans to use machine studying (ML) in sequence manufacturing. The software program Audi has developed acknowledges and marks the best cracks in sheet steel components— routinely, reliably and in a matter of seconds. With this mission, Audi is selling synthetic intelligence on the firm and revolutionizing the testing course of in manufacturing.

As a result of more and more refined design of its vehicles and the top quality requirements at Audi, the corporate inspects all parts straight after manufacturing within the press store.

Along with visible inspection by workers, a number of small cameras are put in straight within the presses. They consider the captured photos with the assistance of image-recognition software program. This course of will quickly get replaced by an ML process.



Software program based mostly on a fancy synthetic neural community operates within the background of this progressive process. The software program detects the best cracks in sheet steel with precision and reliably marks the spot.

We’re presently testing our automated element inspections for sequence manufacturing at our Ingolstadt press store. This methodology helps our workers and is one other vital step for Audi within the transformation of its manufacturing vegetation into trendy sensible factories.

—Jörg Spindler, Head of the Competence Middle for Tools and Forming Expertise

The answer is predicated on deep studying, a type of machine studying that may function with very unstructured and high-dimensional quantities of information equivalent to with photos. The crew spent months coaching the bogus neural community with a number of million check photos.

The largest challenges have been, on one hand, the creation of a sufficiently giant database, and then again, the labeling of the pictures. The crew marked cracks within the pattern photos with pixel precision—the very best diploma of accuracy was required.

The neural community now learns independently from the examples and detects cracks even in new, beforehand unknown photos. The database consists of a number of terabytes of check photos from seven presses at Audi’s Ingolstadt plant and from a number of Volkswagen vegetation.

Synthetic intelligence and machine studying are key applied sciences for the longer term at Audi. With their assist, we are going to proceed to sustainably drive the digital transformation of the corporate.

On this cross-divisional mission, we’re collectively growing a production-ready answer that Audi will use solely within the firm and which is exclusive out there.

—Frank Loydl, Chief Info Officer (CIO) at Audi

The software program was primarily developed in-house, from the thought to the completed prototype. Since mid-2016, the innovation division of Audi IT has been working hand in hand with the Manufacturing Expertise division of the Tools and Steel Forming Expertise Competence Middle.

Sooner or later, high quality inspection utilizing ML will exchange the present optical crack detection with sensible cameras, which includes quite a lot of guide effort. Whether or not doorways, engine hoods or fenders, the digicam presently must be reconfigured for each new element produced within the press store. As well as, false detections frequently happen, for the reason that easy algorithms of the image-processing program are extremely depending on ambient components equivalent to lighting situations and floor properties.

Sooner or later, Audi believes it will likely be potential to use the ML strategy for different visible high quality inspections. If a sufficiently giant variety of labeled datasets can be found, the system may also help paint retailers or meeting retailers, for instance.
