基于不同数据采集方式构建城市三维模型相关技术研究

Research on Construction of Urban 3D Models Based on Different Data Acquisition Methods

为探索基于不同数据采集方式构建城市三维模型相关技术,本文以具有代表性的建筑物为研究对象,通过对无人机倾斜摄影、地面三维激光扫描、手持三维激光扫描仪等三种设备构建三维模型的技术路线、适用范围、数据采集、精度指标对比等方面进行相关技术研究。

In order to explore the relevant technologies for constructing urban 3D models based on different data acquisition methods,this article takes representative buildings as the research object,and conducts relevant technical research on the technical route,scope of application,data acquisition,and comparison of accuracy indicators for constructing 3D models using three types of equipment:unmanned aerial vehicle oblique photography,ground 3D laser scanner,and handheld 3D laser scanner.
