在视觉辅助软管式空中加油系统中,如何在实时图像序列中将加油锥套从复杂背景环境中快速分离出来,对锥套进行快速检测与识别,是一个亟需解决的问题。论文针对加油锥套远距图像目标检测与定位问题,提出了一种基于形状信息的Hough-LS两级锥套目标检测与定位方法。文中首先采用快速霍夫梯度法(FHGM)进行加油锥套预检测,而后利用中心八向搜索法进行锥套边缘提取,最后基于最小二乘椭圆拟合实现加油锥套远距图像目标区域精确定位。实验结果表明,本文可对远距(7~25 m)时的加油锥套图像快速进行识别处理,并将锥套目标定位到精确的区域边界。
在視覺輔助軟管式空中加油繫統中,如何在實時圖像序列中將加油錐套從複雜揹景環境中快速分離齣來,對錐套進行快速檢測與識彆,是一箇亟需解決的問題。論文針對加油錐套遠距圖像目標檢測與定位問題,提齣瞭一種基于形狀信息的Hough-LS兩級錐套目標檢測與定位方法。文中首先採用快速霍伕梯度法(FHGM)進行加油錐套預檢測,而後利用中心八嚮搜索法進行錐套邊緣提取,最後基于最小二乘橢圓擬閤實現加油錐套遠距圖像目標區域精確定位。實驗結果錶明,本文可對遠距(7~25 m)時的加油錐套圖像快速進行識彆處理,併將錐套目標定位到精確的區域邊界。

In the visual-based aerial refueling assistance system, how to separate the refueling drogue from the complex background and do rapid detection of drogue area is an urgent problem. How to detect and locate refueling drogue over a long distance in real-time, a refueling drogue detection and location over a long distance method based on Hough-LS was presented. First, did pre-detection on refueling drogue based on Fast Hough Gradient Method (FHGM), and then extracted taper sleeve edge based on the method of Search in eight directions from the center. Finally, realized refueling taper sleeve detection over a long distance by the least squares fitting ellipse. Experimental results show that, the method has good detection effect for long distance (7 to 25 meters) taper sleeve target and it can locate the precise area boundary.
