mikejuk writes "The open source flight simulator Flight Gear is great fun but it can also be used for serious research. Suppose you want to develop a drone that can roam the seas and spot debris so that ships can be directed to it and pick it up. It's a good idea, but how do you test your methods? The obvious way is to take to the sea and fly a drone over real debris and see what happens. It uses a lot of fuel and generates a lot of sea sickness. Why not just fly a simulated drone over a simulated sea and save the sea sickness? This is what Curtis Olson, project manager at FlightGear and he explains how to get OpenCV to use the simulator as if it was a camera."
