Cognex launches 3D vision system with AI

Cognex Corporation has released what it says is the world’s first AI-powered 3D vison system. The In-Sight L38 3D vision system combines AI, 2D and 3D vision technologies to solve a range of inspection and measurement applications.

The company said 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 more reliable inspection results.

“In factory automation, where fast deployment and reliability are not just desired but essential, the In-Sight L38 offers both,” said Carl Gerst, Executive Vice President of Vision and ID Products. “It’s more than a 3D vision system. It’s an AI-powered solution for achieving new levels of quality and performance in automated inspections.”

The In-Sight L38 is designed to simplify the process of configuring 3D systems by utilising 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 AI-powered 3D tools can be set up in minutes, requiring as few as 5 to 10 labelled images to automate a task. Cognex said that with one tool, users can detect challenging defects, gauge variances in three dimensions and get results in real-world units.

Patented, speckle-free laser optics in the In-Sight L38 minimise 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, and offers more light than traditional systems, which lowers exposure requirements and allows for increased line speeds.
