1. A method of simulating a quadcopter comprising:
recording camera output for one or more video cameras while the one or more video cameras are pointed at an unchanging image;
subtracting a constant signal from the recorded camera output to obtain a camera noise component of the camera output;
generating a simulated camera noise from the camera noise component of the camera output of the one or more video cameras;
adding the simulated camera noise to a plurality of simulated camera outputs of a quadcopter simulator to generate a plurality of noise-added simulated camera outputs; and
sending the plurality of noise-added simulated camera outputs to an Artificial Intelligence (AI) controller coupled to the quadcopter simulator for the AI controller to use to pilot a simulated quadcopter of the quadcopter simulator.
