Collaborative Research: The Generation of Georeferenced Video Mosaics in Support of Submersible and ROV Operations

项目名称：生成支持潜水器和ROV操作的地理参考视频片段项目摘要PIs建议为基于pc的计算机开发一个易于使用的软件包，该软件包可用于转换从任何水下航行器获取的视频图像，在绝对或相对导航网络中操作，并快速生成一组地理参考全景图，然后可以直接在地理信息系统（GIS）中分层。在开发这个软件的过程中，我们希望那些收集视频图像的人能够定量地探索海底相对较大的区域，就像通过航空照片或卫星图像观察陆地过程一样。最初的方法将是开发一个系统，适合于有效地处理深水潜水器潜水的视频图像。他们的目标是使用和完善UNH团队开发的软件，并在几小时内生成地理参考马赛克，以便后续的潜水和采样程序可以优化。他们将专注于建立一个强大的，文档齐全的软件套件，允许广泛的人员进行视频拼接。所建议的处理方法也同样适用于已收集并保存在众多海洋学机构档案中的大量视频数据，以及深潜车辆系统的过去用户。为了测试拼接系统的近实时应用，pi建议在即将进行的两次巡航中在海上构建视频拼接。pi已经召集了一个多学科的科学家小组来测试这个系统，并将其应用于与海洋中脊的海洋地质学和海洋生物学相关的问题，包括在EPR ISS的Alvin潜水器连续潜水中对喷口流体化学的综合测量和喷口群落的采样。基于海岸的近实时和遗留马赛克分析将用于帮助解释在过去十年中反复访问的EPR喷口的群落结构的时间变化。地理参考视频马赛克将被纳入目前为加拉帕戈斯裂谷和EPR国际空间站开发的地理信息系统。

Project Title: The Generation of Geo-Referenced Video Mosaics in Support of Submersible and ROV OperationsProject SummaryThe PIs propose to develop an easy-to-use software package for PCbased computers that is tailored to convert video imagery acquired from any underwater vehicle, operated within both absolute or relative navigation networks, and quickly produce a set of geo-referenced photomosaics, whichcan then be directly layered within a Geographic Information System (GIS). In developing this software, we hope to enable those collecting video imagery to quantitatively explore relatively large areas of the seafloor in the same way that land-based processes can be observed through aerial photographs or satellite imagery. The initial approach will be to develop a system that is suited to efficiently process video imagery from deep submergence vehicle dives. Their objective will be to use and refine the proposed software developed by the UNH group and generate geo-referenced mosaics within a few hours so that subsequent diving and sampling programs can be optimized. They will focus on establishing a robust, and well-documented software suite that will permit video mosaicking by a wide range of personnel. The processing approach proposed will also be equally applicable to the large amounts of video data already collected and sitting in archives at numerous oceanographic institutions and with past users of deep submergence vehicle systems. To test the mosaicking system for near-real-time application, the PIs propose to construct video mosaics at sea during two upcoming cruises. The PIs have assembled a multi-disciplinary group of scientists to test the mosaicking system and apply it to questions relevant to marine geology and marine biology at mid-ocean ridges, including the integrated measurements of vent fluid chemistry and sampling of vent communities on successive dives with the submersible Alvin at the EPR ISS. Shore-based analyses of near-real-time and legacy mosaics will be used to aid in the interpretation of temporal changes in community structure at EPR vents visited repeatedly over the past decade. Geo-referenced video mosaics will be incorporated into a GIS currently developed for the Galapagos Rift and the EPR ISS.
