摘要/Abstract

摘要： 基于某大学图书馆点云数据及航摄相片，本文采用3ds Max与Smart 3D两种方法构建三维模型。一方面，采取人机交互的方式进行建模，将三维激光点云数据导入3ds Max软件建立三维数字模型；另一方面，使用半自动人工方式建模，采用Smart 3D软件，将航摄像片数据经过空三加密、自动建模、贴图等操作后对建筑实体建模。从建模效率、模型美观性、建模精度、适用对象等方面比较了两种建模方式的特点与区别。结果表明，3ds Max更加适用于规则体、高精度建模，同时建模的效率相对较低；Smart 3D建模效率高，更加适用于大场景范围的快速建模。本文研究结论有助于不同需求背景下建模方法的选取，为研究、工程及试验提供了三维建模方法选择参考。

Abstract: Based on the point cloud data and aerial photos of a university library, the 3D model is constructed by using 3ds Max and Smart 3D. On the one hand, the method of human-computer interaction is adopted for modeling, and the 3D laser point cloud data is imported into 3ds Max software to establish the 3D digital model. On the other hand, the semi-automatic manual mode is used for modeling, and the Smart 3D software is used to model the building entity after the aerial camera data is encrypted, automatically modeled, mapped and other operations. The characteristics and differences of the two modeling methods are compared in terms of modeling efficiency, model aesthetics, modeling accuracy and applicable objects. The research shows that 3ds Max is more suitable for regular body and high-precision modeling, while the efficiency of modeling is relatively low; Smart 3D modeling is more efficient and more suitable for rapid modeling in a large range of scenes. The conclusions are helpful to the selection of modeling methods under different requirements, and provide a reference for the selection of 3D modeling methods for research, engineering and experiment.
