基于机载视觉的舰载无人机自主着舰引导技术研究

Research on automatic landing technology of shipboard uav based on computer vision

无人机在现代海军中有着举足轻重的地位,其使用避免了大量人员伤亡。本文针对无人机自主着舰的难题,利用计算机视觉技术对无人机进行着舰引导。本文在设计机载视觉引导技术总体方案的基础上,详细研究了着舰地标识别、相机标定和无人机位姿解算算法。实验结果表明,本文设计的方案可以明显提高无人机自主着舰的可靠性。

The shipboard unmanned aerial vehicle(UAV) plays an important role in the modern navy, and its use avoids a great deal of casualties. In this paper, aiming at the problem of shipboard unmanned aerial vehicle(autonomous aircraft) landing, the airborne vision is used to guide the UAV. On the basis of designing the general scheme of airborne visual guidance technology, this paper studies ship landmark identification, camera calibration and UAV pose calculation algorithm in detail. Experimental results show that the proposed scheme can improve the reliability of UAV autonomous landing.
