可量测全景视频流在胡同实景三维建设中的应用
Application of measurable panoramic video streaming in 3D real-scene construction of Hutongs
摘要
Abstract
The traditional Hutongs in the core area of Beijing,the capital are narrow and widely distributed.It is extremely expensive to achieve a three-dimensional(3D)real-scene construction of the Hutongs through precise 3D reconstruction.In the restricted aviation area,a new geospatial representation method,namely measurable panoramic video streaming can be adopted to obtain 3D,visual,and measurable panoramic video streaming data of Hutongs.The measurable panoramic video streaming integrates the dual advantages of video and geographic information and has the characteristics of visualization,measurability,and rich spatio-temporal information.This paper focused on more than 500 Hutongs in the core area.By optimizing the vehicle-mounted laser measurement system and studying the collection of video streaming data and processing routes of large-scale Hutong areas,the geographic data of measurable panoramic video streaming of the Hutongs was obtained.By relying on the application project for World Heritage along the central axis of Beijing,the points of interest(POIs)for the inconsistent style of the Hutongs were extracted to meet the needs of style monitoring of traditional Hutongs,and the application of Hutong style monitoring based on video streaming data was explored.This research realizes the 3D real-scene construction of Hutongs based on panoramic video streaming,facilitates the geographic information data collection for style monitoring of traditional Hutongs in the application project for World Heritage along the central axis of Beijing,provides spatio-temporal information service experience of panoramic video streaming,and expands the application of 3D real scene.关键词
