Vision System Combines AI, 2D and 3D Technologies

The In-Sight L38 3D vision system combines AI, 2D and 3D technologies to solve a range of inspection and measurement applications. The system creates unique projection images that combine 3D information into an easy-to-label 2D image for simplified training and reveals features not visible with traditional 2D imaging. AI tools detect variable or undefined features, while rule-based algorithms provide 3D measurements to deliver reliable inspection results.

The process of configuring 3D vision systems is easier thanks to embedded AI technology that uses pre-trained models with domain-specific data. Example-based training replaces complex programming steps, which previously required combining many traditional rule-based tools, to streamline application development. The unique AI-powered 3D tools can be set up in minutes, requiring as few as 5 to 10 labeled images to automate a task. With one tool, engineers can detect challenging defects, gauge variances in three dimensions, and get results in real-world units. Speckle-free laser optics minimize visual noise and glare to capture higher resolution images than traditional laser displacement sensors, while a high-powered laser delivers fast acquisition rates to support high line speeds. The high-powered laser meets Class 2 safety standards, eliminating the need for expensive enclosures. It also offers more light than traditional systems, which lowers exposure requirements and allows for increased line speeds.
