Twyn Augmented Reality Based Mobile Visual Inspection

Before components from suppliers get into production, incoming goods control must check and ensure the components’ quality. With Twyn, the German deep tech start-up Visometry has introduced a novel augmented reality based mobile inspection system to check components in real time.

Visometry, the Germany based start-up known for its VisionLib (Augmented Reality Tracking Engine) has introduces its second product called Twyn. This novel mobile inspection system uses augmented reality for a digitalized and highly efficient quality inspection of parts and assemblies. The turnkey solution enables to compare real objects against their CAD specification. Localized through the tablet’s camera, Twyn automatically registers and tracks inspected objects to compare the as-is situation against the as-planned digital twin, using precise augmented reality overlays.

These benefits prove themselves valuable particularly at the beginning of the production process, because downtimes can be avoided by finding errors at an early stage. Using Twyn, all parts, not just samples, can be backed up to reduce scrap, rework and costly recalls.

With its innovative visualization tools and precise auto-alignment of superimposed digital twin and physical object, Twyn finds deviations faster than ever before and allows to check more parts in shorter time. “This reduces the high risk for consecutive errors and follow-up costs in production or for repair tasks in the field”, says Visometry co-founder and COO Dr. Harald Wuest. With an integrated reporting process, defects are captured and tracked digitally from the beginning. The digital by design workflow enables a faster interaction of different business units to quickly identify sources of errors and supports them to consider improvements sooner in the product development cycle.

Twyn has been in regular use by pilot customers. One of them is agricultural machinery manufacturer Krone. With highly complex products and numerous configuration variants, Krone uses Twyn to improve quality inspection and to reduce complexities of the inspection process. Being able to find errors more quickly while increasing the inspection frequency, Krone avoids down times more often and speeds up iteration cycles between assembly and construction. “But what really impressed us was that Twyn enables us to perform checks unrealizable so far:  Because Twyn is all mobile running on a tablet, our engineers can now bring the inspection to (even very big) assemblies, not the other way around.” says Andreas Audick, quality engineer at Krone. Parts do not have to be transported, they can be inspected right on site at, practically speaking, any time in the production cycle: incoming goods reception, end of line, or for quality documentation before the shipment.

For Visometry it was just an obvious next step to go deeper into the direction of quality assurance. Its core augmented reality tracking SDK VisionLib allows to align CAD to captured counterparts fast and accurately, which makes the enterprise-grade object tracking a cornerstone for industry 4.0 and digital twin technologies. According to Wuest, many companies still struggle putting AR to regular use, especially because of the laborious preparation effort of AR systems. “With Twyn we have simplified and eased the process to a minimum of data preparation, so users can focus on the inspection and engineering tasks itself, without becoming at first an IT or AR professional”, explains Wuest further.

At Visometry, however, this is just the next step towards Industry 4.0. With its background of more than 10 years in Computer Vision and mobile computing, Visometry is currently stretching the limits of its augmented reality tracking. The aim is to completely automate the inspection process so that Twyn checks for the existence of parts, whether the right parts are assembled, or whether position and orientation are accurate. “We have first pilots of this automated inspection running with promising feedback from pilot users.” says Wuest.

Find Defects Instantly

Using augmented reality overlays, Twyn points out aberrations instantly and enables to identify more errors in shorter time compared to established 3D measurement techniques. By being faster in the process, you users increase the inspection rate by up to a factor of 6.

Decreased Time for Setup

Twyn uses marker-less 3D model alignment to auto-register manufactured parts to CAD models significantly reducing the tooling time needed to prepare inspections and takes just a couple of clicks to setup new inspection cases based on CAD or 3D data.

Mobile | Flexible | Digital.

With Twyn on a tablet, inspections can be performed directly on the spot, instead of bringing heavy & bulky samples to a measurement machine or test bench allowing for the inspection of parts location independently, at any time in the production cycle – incoming goods receipt, assembly, or end of line.
