Summary

无人机景象匹配视觉导航技术是实现无人机自主飞行、高效侦察与精确打击的关键技术之一。该技术通过分析当前基于景象匹配的无人机视觉导航技术研究现状,发现国外研究主要集中于单独利用视觉图像信息进行飞机姿态、导航信息提取以及联合IMU等传感器的组合导航系统。国内该领域的研究鲜见报道,但对该技术所涉及的惯性组合导航、视觉/激光测距三维地图重建、视觉导航着陆应用等技术进行了大量研究。无人机景象匹配导航系统的核心是图像匹配算法,其性能好坏直接决定了导航系统的性能。适配区选取是景象匹配导航的关键技术,目前主要是依靠人工选取,但人工选取匹配区工作量大,速度慢,易受操作人的经验、专业等因素的影响。图像匹配是把从相同或不同传感器在同一区域获取的两幅图像在空间上进行对准,以确定出这两幅图像间相对位置关系的过程。未来无人机景象匹配视觉导航工作需要突破的关键技术包括提高图像匹配算法的精度和效率、实现实时图像匹配、提高系统的鲁棒性和抗干扰能力等。
