Cognex Corp. has added 3-D vision to its VisionPro software for machine vision applications. VisionPro 3-D delivers accurate, real-time 3-D position information to automate assembly verification, logistics and robot applications. Based on proprietary PatMax and other alignment technologies, it works with fixed or robot-mounted cameras. The software is integrated with the existing VisionPro library, providing users with access to a variety of identification and inspection tools. It uses multiple sets of 2-D features found in the company’s alignment tools, including PatMax, PatFlex and other geometric pattern matching tools that tolerate nonuniform lighting and remain reliable even when patterns are partly covered. This ensures accurate part location under challenging conditions. The software continues to perform even if some part features are not visible.
