摘要: 为研究道路空间视距对重特大道路交通事故的影响,首先,根据无人机航测影像重建事故现场的三维模型、恢复道路线型数据;然后,提出基于三维重建模型及道路线型恢复数据的空间视距计算方法;其次,在Open Scene Graph(OSG)三维渲染引擎中搭建基于航测数据的空间视距计算平台;最后,以2016年8月贵州某地发生的一起重特大道路交通事故为研究对象,对所提出的空间视距计算方法进行案例分析及验证。研究结果表明:用所建立的计算方法,能够解决护栏、标志牌和路侧景观等道路附属设施对视距的影响及道路实际情况与施工图或竣工图数据不一致等情况下的空间视距计算问题。

Abstract: The paper was aimed at exploring the influence of road spatial sight distance on the serious road traffic accidents. Firstly, a 3D model was built for the accident scene and the road shape data were restored according to the aerial image of the unmanned aerial vehicle. Then, a spatial sight distance computing method was worked out based on the 3D reconstruction model and the road shape restoration data. Next, an aerial survey data based spatial sight distance computing platform was built in Open Scene Graph(OSG). Finally, the method was used to analyzing a certain serious road accident which occurred in Guizhou in August 2016. The results show that the method worked out by the authors can be used to solve the spatial sight distance computing problems even if the road accessory facilities impacted the spatial sight distance, such as guardrail, signs and roadside landscape, impact the spatial sight distance, and road actual situation is inconsistent with the construction or as-built drawings.

Key words: serious road traffic accidents, aerial survey data, three dimensional reconstruction, data restoration, spatial sight distance computing
