历史地段保护性改造中数字化勘查技术应用研究——基于珠江三角洲地区的实践

A Study on the Application of Digital Technologies of Architectural Surveying in the Renovation of Historic Districts Practice Based in the Pearl River Delta

以珠海北山村和广州泮塘五约两处历史地段的保护性改造为例,分析了珠三角地区历史地段在规划设计阶段的主要技术难点,探索了无人机技术、数字照相建模技术、移动三维激光测绘技术、点云矢量化技术等数字化勘察技术在应对这些技术难点的过程中所发挥的作用,提出了新的面向建筑学的数字化勘测的工具和方法。

This paper uses two projects of protective renovation in Beishan Village in Zhuhai and Pantang Wuyue in Guangzhou as examples to analyze the main technological difficulties in the planning of historic districts in the Pearl River Delta. It explores the application of digital technologies of architectural surveying, including UAV technology, digital photography modeling technology, mobile 3D laser survey technology, and point cloud vectorization technology in tackling the difficulties, and advocates for new architectural tools and methods in digital surveying.
