Ứng dụng phương pháp ảnh máy bay không người lái xây dựng bản đồ 2D và mô hình hiện trạng 3D phục vụ thiết kế quy hoạch

Abstract

The article presents the topographic survey work using unmanned aerial vehicle (UAV) images to build 2D maps and 3D current status models. This technology has been used in many areas of life, but in Vietnam in planning design, it has not been widely applied.. Planning architects still follow the traditional method of relying on the 2D basemap database plus input data collected from various sources and at the request of the Investor to analyze and design the plan.. The products created from the above inputs are 2D detailed design drawings and 3D design models. It will be difficult to avoid shortcomings and limitations that will affect quality and slow progress due to design adjustments.. The design and application of the results from UAV equipment such as 2D topographic maps, image maps, 3D current status models, digital elevation models (DEM), point cloud data, etc. will improve the quality of design and planning management, in addition to adding an approach to green, sustainable design, responding to climate change and natural disasters.
