Machine vision software adds 3D vision

Cognex Corporation added 3D vision to VisionPro to work in real-world conditions, particularly in assembly, logistics, and robot applications.


Cognex Corporation added 3D vision capabilities to VisionPro machine vision software. VisionPro 3D delivers accurate, real-time, three-dimensional position information to automate challenging assembly verification, logistics and robot applications, the Cognex said. VisionPro 3D works with any number of fixed or robot mounted cameras for complete application flexibility. 

"We’re taking our advanced 3D tools and putting them in VisionPro, the premier programmatic environment for system integrators and OEMs." said Dr. Markku Jaaskelainen, Cognex vice president and business unit manager for vision software. "Our partners are already using VisionPro 2D tools for a wide range of vision and robotic applications. VisionPro 3D opens new opportunities for them to solve more complex alignment applications. And, because it is integrated with the existing VisionPro library, they have access to VisionPro’s wide range of identification and inspection tools. This expands the value they can add to a project."

Robust 3D location

VisionPro 3D reportedly uses multiple sets of two-dimensional features found by field proven Cognex alignment tools, including PatMax, PatFlex and other geometric pattern matching tools. These tools tolerate non-uniform lighting and remain reliable even when patterns are partly covered, ensuring accurate part location under the most challenging conditions.

Application performance is enhanced by high-precision Cognex calibration tools that adjust for optical distortion and camera position, and synchronize cameras with vision-guided robots—key to the success of any 3D application.

"VisionPro 3D is designed to work under real-world conditions," said Dr. David Michael, director of core vision technology. "It continues to perform if some part features are not visible. It even compensates if one of the cameras has moved out of alignment, so that production can continue uninterrupted."

VisionPro 3D is reportedly designed for a variety of stationary and robotic applications, such as racking/de-racking and de-palletizing, as well as kitting and assembly verification in automotive and other precision manufacturing industries.

VisionPro 3D offers a starter kit for fast start-up and easy training, which includes the VisionPro 3D software and a turnkey training application. The training application comes complete with source code and all the hardware needed to get started quickly, including cameras, a tripod, and precision calibration plates.
