Footage taken from the onboard camera of a Parrot AR Drone whilst demoing OCRDrone at NodeCopter Southampton.
OCRDrone uses the PNG video stream to continuously save camera footage to the filesystem, passing each image to nodecr (https://github.com/joscha/nodecr) for text recognition. If the text is recognised as a valid command, it is then translated into flight commands in real-time.
Video created by stitching all the saved PNG images collected from the video stream.
