摘要
为了实现三维模型的快速构建,笔者针对现有倾斜摄影数据三维建模中存在的数据精度低且单体化困难等问题,以GMglobal平台为基础,基于倾斜摄影数据生成目标建筑物的倾斜摄影模型,基于矢量数据生成目标建筑物的矢量模型,将倾斜摄影模型与矢量模型进行融合处理,生成目标建筑物的三维融合模型。该方法既节省了建模成本,又保留了模型的真实感,而且保持了模型和相关数据的强关联,解决了精度低、单体化困难等难题,实现了三维模型的快速构建。
In order to realize the rapid construction of three-dimensional model, aiming at the problems of low data accuracy and difficult monomer in the three-dimensional modeling of existing tilt photography data, based on the GMglobal platform, the author generates the tilt photography model of the target building based on the tilt photography data, and generates the vector model of the target building based on the vector data, The tilt photography model and vector model are fused to generate the three-dimensional fusion model of the target building. This method not only saves the modeling cost, but also retains the realism of the model, maintains the strong correlation between the model and relevant data, solves the problems of low precision and difficult monomer, and realizes the rapid construction of three-dimensional model.
