集成激光扫描与无人机航摄的古建筑测图技术研究

Mapping Technology Research of Historic-building Based on the Integration of Laser-scanning and UAV-imaging

本文对无人机倾斜航摄与室内外三维激光扫描的空地一体实景建模技术进行系统研究,重点是如何实现古建筑高精度三维建模、土木工程平面图立面图剖面图及大样图绘制等。相较于传统作业模式,空地一体实景建模技术拥有成果丰富、效率高、劳动强度低及成本低等特点。本文以广东省珠海市会同村古建筑为例,详细分析了三维激光扫描与无人机倾斜航摄相结合建模、及切片制图的技术流程与成果质量,从而展现该古建筑保护测图新技术的优势。

This paper presents a systematic research on air&ground-based observing and real scene modeling technol‐ogy of UAV oblique-imaging and indoor&outdoor 3D laser scanning,especially focused on the high-precision 3D modeling of ancient buildings,as well as the due civil-engineering mapping of plane,elevation,section,local detail and so on.Compared with the traditional mapping technology,the air&ground-based observing and real scene modeling technology owes the special characteristics as rich-product,high-efficiency,low-labor-payment,and low-cost.Relevant jobs of an ancient building of Huitong Village in Zhuhai City,Guangdong Province is presented as an example in the paper,and quanti‐tative analyzing is made for the technical process and modeling accuracy of 3D laser scanning and UAV oblique imaging modeling and slice drawing,thus the advantages of this new technology in ancient building protection mapping are proved carefully.
