Beaglebone: Video Capture and Image Processing on Embedded Linux using OpenCV | derekmolloy.ie
How do you use OpenCV to capture and image process frames so that you can build computer vision applications under Linux on the Beaglebone – I do this using the boneCV.cpp program as described below. This code uses the OpenCV library which is available on the Angstrom distribution of the Beaglebone. Finally, I write a small program boneCVtiming.cpp to test the performance of the Beaglebone black for capturing and processing image data.
