Audi optimizes peculiarity inspections in a press emporium with synthetic intelligence

Due to a increasingly worldly pattern of a cars and a high peculiarity standards during Audi, a association inspects all components directly after prolongation in a press shop. In further to visible investigation by employees, several tiny cameras are commissioned directly in a presses. They weigh a prisoner images with a assistance of image-recognition software. This routine will shortly be transposed by an ML procedure. Software formed on a formidable synthetic neural network operates in a credentials of this innovative procedure. The module detects a excellent cracks in piece steel with a pinnacle pointing and reliably outlines a spot.

“We are now contrast a programmed member inspections for array prolongation during a Ingolstadt press shop. This process supports a employees and is another critical step for Audi in a mutation of a prolongation plants into complicated intelligent factories,” settled Jörg Spindler, Head of a Competence Center for Equipment and Forming Technology.

The resolution is formed on low learning, a special form of appurtenance training that can work with really unstructured and high-dimensional amounts of information such as with images. The group spent months training a synthetic neural network with several million exam images. The biggest hurdles were on a one hand, a origination of a amply vast database, and on a other hand, a supposed labeling of a images. The group noted cracks in a representation images with pixel pointing – a top grade of correctness was required. The bid was value it given a neural network now learns exclusively from a examples and detects cracks even in new, formerly different images. The database consists of several terabytes of exam images from 7 presses during Audi’s Ingolstadt plant and from several Volkswagen plants.

“Artificial comprehension and appurtenance training are pivotal technologies for a destiny during Audi. With their help, we will continue to sustainably expostulate a digital mutation of a company,” emphasized Frank Loydl, Chief Information Officer (CIO) during AUDI AG. “In this cross-divisional project, we are jointly building a production-ready resolution that Audi will use exclusively in a association and that is singular in a market.” The module was especially grown in-house, from a thought to a finished prototype. Since mid-2016, a creation dialect of Audi IT has been operative palm in palm with a Production Technology multiplication of a Equipment and Metal Forming Technology Competence Center.

In a future, peculiarity investigation regulating ML will reinstate a stream visible moment showing with intelligent cameras. This involves a good understanding of primer effort. Whether doors, engine hoods or fenders – a camera now has to be reconfigured for each new member constructed in a press shop. In addition, fake detections frequently occur, given a elementary algorithms of a image-processing module are rarely contingent on ambient factors such as lighting conditions and aspect properties.

In a future, it will be probable to request a ML proceed also for other visible peculiarity inspections. If a amply vast series of labelled datasets are available, a complement can also support paint shops or public shops, for example.
