Abstract: In this paper, an external vision based robust pose estimation system for a quadrotor in outdoor environments has been proposed. This system could provide us with approximate ground truth of pose estimation for a quadrotor outdoors, while most of external vision based systems perform indoors. Here, we do not modify the architecture of the quadrotor or put colored blobs, LEDs on it. Only using the own features of the quadrotor, we present a novel robust pose estimation algorithm to get the accurate pose of a quadrotor. With good observed results, we get all the four rotors and calculate the pose. But when fewer than four rotors are observed, all of existing external vision based systems of the quadrotor do not mention this and could not get right pose results. In this paper, we have solved this problem and got accurate pose estimation with IMU(inertial measurement unit) data. This system can provide us with approximate ground truth outdoors. We demonstrate in real experiments that the vision-based pose estimation system for outdoor environments can perform accurately and robustly in real time. (More)
