摘要
根据分形理论,建立三维路面模型。利用路面纵断面的部分信息点的高程数据,对路面纵断面的不平度进行分形插值模拟。由于路面具有自相似性的特性,可采用垂直比例因子确定的分形插值曲面的方法,以达到对路面的三维重建,为车辆工程、道路工程等领域中的路面三维建模提供了一个新的思路。
According to fractal theory,3-D road model is generated and the longitudinal section of the road part of the information point of elevation data was used to simulate the road roughness on fractal interpolation. Because of the characteristics of self-similarity,the vertical scale factor was used to determine the method of fractal interpolation surface,in order to achieve 3-D reconstruction of the road a new way of establishing 3-D road model in vehicle engineering,road engineering and other fields is provided.
