A Visualization Progress Management Approach of Bridge Construction Based on Mixed Panoramic and Oblique Photogrammetry

Bridge construction progress management is critical to project management, quality supervision and risk control. This research presents a method of management the progress of bridge construction with a mixture of panorama and oblique photogrammetry. Firstly, the panoramic images of the bridge construction site were obtained by using the Unmanned Aerial Vehicle (UAV). Secondly, the panoramic images were processed by oblique photography measurement technology, and the 3D real models of the bridge construction site were established. Finally, the visualization management platform of bridge construction progress was established to support the management and analysis of bridge construction progress. Taking the construction management of the Zhuankou Yangtze River Bridge in Wuhan as an example, the construction progress management was carried out by using this method. The result shows that the method is simple and feasible and has wide application prospect in large-scale construction.
