Abstract:With the continuous advancement and development of live-action 3D technology, the live-action 3D data obtained by the oblique photography technology is integrated into the collecting-view 3D platform, which can achieve the rapid 3D modeling of roads. By overlaying the spatial control elements, current limiting factors, etc., the planned three-dimensional visualization analysis is achieved. Taking the optimization study of the road network in the Xianmahu cluster as an example, the feasibility of the 3D road network optimization method based on real scenes is verified, which makes the planned road network better fit with the terrain, better coordinate with status quo control factors, and better hydrophilic with river system in order to avoid the large-scale excavation and filling in urban construction. The good ecological and economic benefits are obtained, and the concept of green ecological development is practiced.
