Study and Application of Lightweight Processing Method for Realistic 3D Data

摘要:

本文探讨了实景三维数据的标准化与轻量化入库处理方法及应用。实景三维技术成为现代基础设施的关键，随着数据量的激增，轻量化处理变得至关重要。文章概述了实景三维数据的定义、获取技术及在自然资源管理、城市规划等领域的应用。为优化处理，引入LOD1.3技术，提升数据加载和渲染效率。在轻量化处理上，介绍了数字正射影像和倾斜摄影三维模型的处理方法，采用LOD1.3技术平衡信息保留与数据减少，通过切片技术和高效数据库存储，建立时空索引，最终，通过Web服务实现模型的实时访问和呈现。

Abstract:

In this paper, standardization and lightweight storage processing methods and applications of 3D real scene data have been studied. Realistic 3D technology is the key of modern infrastructure. Accompanying with the volume of data explodes, lightweight processing becomes critical. The definition, acquisition technology and application of 3D data in natural resources management and urban planning have been overviewed. In order to optimize the processing, LOD1.3 technology is introduced to improve the efficiency of data loading and rendering. In terms of lightweight processing, the processing method of digital orthophoto and oblique photography 3D model have been introduced. By using LOD1.3 technology to balance information retention and data reduction, through slicing technology and efficient database storage, spatio-temporal index has been established. Finally, the model can be accessed and rendered in real time through web services.
