Canon EOS Control supports LabVIEW integration with Canon EOS cameras.
Canon EOS Control is a software add-on for LabVIEW that provides a library for controlling Canon EOS cameras through a USB connection. The add-on includes an interface to capture and transfer images, display and control the camera view finder, and control camera parameters. Canon EOS Control by Ackermann Automation also supports simultaneous control over multiple cameras. You can display captured images in the LabVIEW IMAQ control and use them with NI-IMAQ functions.
