摘要
高速公路的三维模型在工程量计算、公路管理、项目审计、三维演示等应用中具有重要作用。提出了一种基于平面设计图的高速公路三维建模方法,首先读取高速公路横断面设计图文件,按照图注对平面设计图进行断面分割和解析,然后把提取的横断面轮廓线沿公路中心线变换到同一坐标系中,最后采用最短对角线法进行三角片表面重构,建立高速公路的三维模型。该方法提高了高速公路三维建模的效率和精度。
3D models of highway play an important role in engineering calculation, management of highway, project auditing and 3d presentation. An approach to 3d modeling of highways was proposed based on section plans. First, section plan files were read and segmented into several cross sections according to figure legends. Then, the cross sections along the center line of the highway were translated into the same coordinate frame. Finally, triangular surface were constructed with the shortest diagonal method. The proposed method improves the efficiency and accuracy of 3d modeling of highway.
