I am writing an application to read image frames from bebop2 's bottom facing camera and feed this frame to an optical flow application.

My problem is with the bebop downward facing camera. I had written code to initialize camera chip and applied MT9V711 patch (see: After all that the image being read from the camera is all noise. image
