SpinnakerCapture

Prerequisites:

  • bonsai Spinnaker Library
  • Spinnaker SDK 1.29.0.5 from the FLIR website

tip

Write video to file using VideoWriter

tip

To visualise the video during acquisition, install the bonsai Vision Design Library and open Bonsai.Vision.Design.IpIImageVisualizerfrom the Image output node of the respective image capture node

caution

Runtime error: Unable to acquire camera frame

One possible reason is that the camera is currently open in SpinView.
