视频数据库技术在大洋资源调查中的应用研究

Application of Video Database Technique in Marine Resource Survey

在我国近年的大洋科学考察中,深海摄像作业作为重要的可视化调查手段之一,在大洋结核、结壳、热液硫化物以及天然气水合物调查中发挥了重要作用,每年航次均取得近百小时的视像资料数据,海量的视频数据包含了大量的地质信息,如何管理获得的大量视像数据以及如何检索、分析、利用这些数据资源,直接关系到航次获得的视像数据在大洋资源评价中的意义和价值。文中从视像数据的特点出发,结合多媒体技术的开发特点,阐述了我国大洋摄像视频数据库的建立、实施技术方案,以达到与同行的技术沟通,提高我国视频数据库技术在大洋调查中的应用效果。

In recent years of Chinese scientific survey and research of ocean mineral resources, deep-sea video camera recording operation is one of important visualized survey means, which has played an important role in the investigation of polymetallic nodules, cobalt-rich crusts, hydrothermal sulfide and gas hydrate, and has yielded about 100 hours of video data every year. The mass video data contains a large amount of geological information. How to manage such large amount of video data and how to analysis and interpret these data, has direct effects and significance on evaluation of the ocean mineral resources. The implementation of an ocean video database with visual database technique is presented, which is realized in combination of the characteristics of the ocean video data and the characteristics of multimedia technologies. The purpose is to share experience with peers and to promote the application of video database technology in the survey on ocean mineral resources.
