无人机近距离摄影的建筑三维测绘模型构建

Construction of 3D mapping model for UAV close-up photography

三维测绘建模技术在各个行业及领域中都有广泛应用,如林业保护、城市服务、文物保护、工程测量等。本文探讨了无人机近距离摄影测绘技术,并以释迦塔三维建模为例介绍了近摄测绘的基本原理、测绘方式、常用坐标系,分析了三维测绘建模的关键步骤,包括建模基础、航线设计和摄影流程。运用无人机技术收集释迦塔的影像材料,建立精确的三维模型。该模型经过人工测量验证,误差微小,证实了该技术在建筑三维模型构建中的可行性和有效性。

3D surveying and mapping modeling technology has a wide range of applications in various industries and fields,such as forestry protection,urban services,cultural relics protection,engineering surveying and so on.This study discusses the UAV close-range photographic surveying and mapping technology and takes the 3D modeling of Shakya Pagoda as an example,introduces the basic principle,surveying and mapping method,and common coordinate system of close-range surveying and mapping,and analyzes the key steps of 3D surveying and mapping modeling,including modeling basis,route design and photography process.The UAV technology was used to collect the image materials of Shakya Pagoda,and the accurate 3D model was established.The model was verified by manual measurement and the error was small,which confirmed the feasibility and effectiveness of the technology in the construction of 3D building model.
