The Setup
Multiple fixed cameras are located around an enclosed inspection chamber, observing the entire part from all directions.
The chamber is illuminated with dedicated light sources that are synchronized to different cameras to provide optimum illumination while capturing photographs while the enclosed chamber eliminates the effect of the ambient light on the factory floor.
Collect Data and Create a Visual Digital Twin
Each camera captures images of the entire part and all features from multiple angles—providing a complete model of the part and creating a visual digital twin of the part within seconds.
Unlike conventional vision technologies, each feature is observed multiple times by different cameras during in multi-camera technology. This creates a unique capability called self-diagnostics and camera redundancy, which drastically improves the systems robustness.
Store the Visual Digital Twins for Advanced Traceability and Retroactive Inspection
The collected inspection data is aggregated with each part's S/N and other meta information. While the images are passed to inspection algorithms in real-time, the data is stored in a database.
Since the images provide a visual digital twin of each part, they can be recalled during anytime of the production lifecycle to conduct new inspections on the parts retroactively even after the parts are shipped.
Inspect in Real-Time on the Visual Digital Twins
Machine vision algorithms detect the features defined in the inspection program and advanced photogrammetry algorithms conduct all measurements directly on the visual digital twin of the part in real-time.
Since the entire inspection process is done fully-digitally on the visual digital twin of the part, the inspection cycle time is drastically cut down to 30 seconds even for hundreds of features.

Inspect Retroactively on Visual Digital Twins
Since the data collected represents the entire part and functions as a visual digital twin, it can always be recalled to conduct new inspections even after the parts are shipped.
You can update the inspection specifications for existing features or define completely new features and conduct new inspections fully virtually—eliminating manual sorting activities and total batch recalls.
