摘　　要：本文研究路面建模中的真实感显示问题,应用线阵相机采集的路面纹理影像,围绕纹理映射方法来构建具有真实感的公路模型。路面影像采用四叉树方式组织索引,在原始纹理映射的基础上,根据光照原理为路面模型添加光强度信息,考虑到常见沥青和水泥路面的材质特点,选用法线映射技术来进一步增强路面的真实感,实验表明通过上述处理方法可以有效地增强车载系统公路建模的真实感。This paper studies the realistic road modeling technology. A road model full of sense of reality is built mainly by texture mapping. The textures needed to map on the road model is gathered by line scan cameras. The paper uses a quadtree to index the textures. Based on the study,considering the material features of common asphalt and cement pavement,the paper uses normal map technology to further enhance the reality of the model. Experiments show that the sense of reality of the highway model can be effectively enhanced by using the above technologies.
