首先设计了一个基于前向运动视频的高速铁路运行环境全景图成像框架,在此框架基础上,提出了一种基于前向运动视频的全景图快速生成算法。最后,对所生成的全景图进行三维重建,模拟列车真实运行环境。实验结果表明,该方法在数据存储、数据的快速浏览等方面有着很大优势,并且可以用于铁路运行环境的自动检测、列车虚拟驾驶等方面。
A panoramic representation framework for high-speed railway was designed based on the forward moving vid- eo, and then a fast method to create panorama was proposed based on forward moving video. The created panoramas in 3D space were reconstructed to imitate the real environment of train running. The experimental results showed that this method had many advantages in data storage and scene browsing, which had the potential to be used in many aspects, such as inspecting railway environment and virtual driving of the train.
