    摘要:

    跑道作为机场的关键设施,是飞机着陆和减速滑行的区域,通过视觉定位方法计算飞机相对跑道的位置,可以作为辅助飞机快速平稳着陆的一种思路。视觉传感器所需成本较低,对安装环境要求不高,本文旨在设计一个仅靠视觉传感器对飞机进行定位的辅助着陆系统,运用目标检测和视觉定位两个模型,计算飞机相对跑道的位置。首先搭建出等比例微缩的机场跑道模型,视觉传感器产生运动模拟飞机飞行路径,目标检测模型通过机载视觉传感器获取的图像识别出跑道区域,随后视觉定位模型提取图像中跑道区域特征点,计算飞机相对跑道的位置。分别对目标检测和视觉定位两部分的实现原理及难点进行阐述,尝试将目标检测和视觉定位结合起来实现飞机降落时的定位,描述辅助着陆系统设计的整体思路。

    Abstract:

    As the key facility of the airport, runway is the area of aircraft landing and decelerating taxiing. The position of the aircraft relative to the runway can be calculated by visual positioning method, which can be used as an idea to assist the rapid and smooth landing of the aircraft. The cost of vision sensor is low, and the requirement of installation environment is not high. This paper aims to design an auxiliary landing system for aircraft positioning only by visual sensor, and calculate the position of the aircraft relative to the runway by using two models of target detection and vision positioning. Firstly, an equal scale miniature airport runway model was built. The visual sensor generated motion to simulate the flight path of the aircraft. The target detection model identified the runway area through the image obtained by the airborne visual sensor. Then, the visual positioning model extracted the runway area feature points in the image and calculated the position of the aircraft relative to the runway. This paper expounds the implementation principles and difficulties of target detection and visual positioning, tries to combine target detection and visual positioning to realize the positioning of aircraft landing, and describes the overall idea of auxiliary landing system design.
