摘要:
视频数据具有获取便捷、表达直观、信息丰富的特性,使其成为地理信息系统(GIS)领域一种重要的数据源. 同时,视频数据与GIS 系统的集成应用已逐渐成为当前国际上的一个研究热点和新兴产业生长点. 本文从数据采集、数据解析与数据组织检索的角度对视频空间化方法进行系统归纳与总结,详细介绍了视频数据与空间信息采用的字符叠加、音频调制、外部关联以及嵌入视频容器4 种集成方式、原理以及特点;并阐述了单幅、双(多)幅视频三维建模、量测原理与方法,尤其对其核心问题相机标定进行了深入的剖析;同时总结提炼了视频/图像的基于
Abstract:
With the characteristics of convenient acquisition, intuitive representation and rich information, video has become an important GIS data source. At the same time,the applications of video integration with GIS systems have gradually become a research focus in the world and an emerging industrial growing point. In this paper,we concluded and summarized the methods of video spatialization from three aspects including data collection, data parsing and data organization and retrieval. Firstly the methods,principles and characteristics of four ways to integrate spatial information into video are addressed respectively. They are character overlay,audio modulation,external association and embedded video container. Secondly the methods and principles of three-dimensional modeling,geometric measurement principles and methods of single image or double(multiple)images are elaborated. And also the core issue of camera calibration is analyzed especially. Thirdly the video/ photo organizational strategy based on location retrieval is summarized. Finally,the typical applications of video GIS were introduced and its future development was also discussed.
