基于动态分段的三维线性场景动态构建方法研究

Research on 3D Linear Scene Dynamic Construction Method based on Dynamic Segmentation

由于线性场景狭长的特点,在线性场景的构建时往往不需要或者不优先需要线性场景区域外的其他场景要素。针对此问题,提出一种基于动态分段的三维线性场景构建方案。首先以事件为驱动,将事件进行分类,并根据分类的结果进行线性场景的动态分段方案的设计。然后将分段结果利用动态场景描述的方式进行三维线性场景的精细化描述,实现三维线性场景中地理要素的精准动态变化表达,提升三维线性场景的构建效率。最后通过高速公路应急救援模拟三维线性场景构建实验,验证了方法的可行性。

Due to the narrowness of linear scenes, other scene elements outside the linear scene area are usually not needed or not prioritized. To deal with this problem, a 3D linear scene construction scheme based on dynamic segmentation is proposed. This study firstly takes events as the driver, classifies them, and designs the dynamic segmentation scheme of linear scenes with the result of the classification;then the segmentation results are used to refine the 3D linear scene description by dynamic scene description. It can not only realize the precise dynamic variation expression of the geographical elements in 3D linear scenes, but also improve the construction efficiency of 3D linear scenes. The viability and superiority of this approach is verified by a highway emergency rescue simulation 3D linear scene experiment.
