Programmable automation controllers with vision capability

With the addition of machine vision, engineers can use CompactRIO and NI Single-Board RIO devices in a variety of advanced measurement and control applications. It is said to be excellent for autonomous and semi-autonomous robotics applications for obstacle avoidance, pattern recognition and simultaneous localisation and mapping (SLAM), where advanced control and vision functionality are required. Industrial surveillance applications served include both machine condition monitoring and critical vessel monitoring, when connectivity to infrared cameras is required. Finally, the real-time OS and integrated field-programmable gate arrays (FPGAs) used with both CompactRIO and NI Single-Board RIO eases the process of FDA validation for embedded medical devices.

Machine vision systems consist of two parts: image acquisition and image processing. To acquire images, NI vision acquisition software has expanded to support Internet Protocol (IP) cameras, including those from Basler Vision Technologies. In addition to native IP camera support, National Instruments Alliance Partner moviMED has released the AF-1501 analogue frame grabber for NI C Series products that can acquire monochrome images. To process images, engineers now can program and deploy image processing libraries to CompactRIO and NI Single-Board RIO deployment targets with NI LabVIEW 2009 using the NI Vision Development Module 2009 software, which contains hundreds of image processing and machine vision functions.

Size, speed and reliability

Ben Engelen, Senior Project Engineer for Vision and Measurement at Philips GTD Mechanization, comments: "At our Global Technology Development facility, we are always looking to optimise the size, speed and reliability of our manufacturing machines. The CompactRIO platform provides the high-speed determinism we need for efficient and precise component placement. The new MoviMED AF-1501 frame grabber module helps us integrate video feedback into the same platform and fully automate the entire process."

Engineers can add vision capabilities to the following CompactRIO and NI Single-Board RIO controllers: NI cRIO-901x, NI cRIO-902x and the NI cRIO-907x and NI sbRIO-96xx systems.
