Fast camera array auto-calibration for optical navigation

The infrared camera array devices, which are important components of the air robot automatic optical navigation system, need to be calibrated for keeping the effectiveness and precision of tracking and location. We propose a brand new method for automatic calibration of infrared camera array, we focus on the rotation matrices and translation matrices between the cameras and the world coordinate. We conduct experiments to evaluate the performance of our calibration method on both simulative data and real environment, the results demonstrate the out performance of our method.
