基于倾斜摄影的机场导航设施快速三维建模

Airport Navigation Facilities Based on Oblique Photography 3D Rapid Modeling

倾斜摄影技术凭借其短耗时、高精度和低成本的特点,近年来在测绘、遥感等领域被广泛应用。由于机场平时有飞机运行,难以在短时间内获取机场区域的航拍影像等数据,特别是对于建模精度要求比较高的天线等设施来说更是如此。以机场下滑台这一有天线的复杂建筑为例,开展基于倾斜摄影的免像控点单相机快速建模方法研究,得出最适合的快速建模方法。实验结果表明,方法能够在短时间内完成高精度的机场复杂导航设施三维建模,可以满足快速低成本对机场进行实景三维建模的要求,满足人和三维场景的交互,对飞机模拟训练、机场土地管理有研究意义。

With its short time-consuming,high-precision and low-cost characteristics,oblique photography technology has been widely used in surveying and mapping,remote sensing and other fields in recent years.Because the airport usually has airplanes in operation,it is difficult to obtain data such as aerial images of the airport area in a short time,especially for facilities such as antennas that require relatively high modeling accuracy.This method takes the airport GP glide path,a complex building with antenna as an example,to carry out research on the rapid modeling method of a single-camera free-image control point based on oblique photography.Find the most suitable strategy for rapid modeling.The experimental results show that this method can complete the high-precision 3D reconstruction of the airport's complex navigation facilities in a short time.
