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.

项目名称：支持潜水器和 ROV 操作的地理参考视频马赛克的生成项目摘要 PI 建议为基于 PC 的计算机开发一个易于使用的软件包，该软件包专门用于转换从任何水下航行器获取的视频图像，这些图像在水下航行器和 ROV 内运行绝对或相对导航网络，并快速生成一组地理参考照片马赛克，然后可以直接在地理信息系统 (GIS) 中分层。在开发该软件时，我们希望使那些收集视频图像的人能够定量探索相对较大的海底区域，就像通过航空照片或卫星图像观察陆地过程一样。最初的方法是开发一种适合高效处理深潜车辆潜水的视频图像的系统。他们的目标是使用和完善 UNH 小组开发的拟议软件，并在几个小时内生成地理参考马赛克，以便优化后续的潜水和采样计划。他们将专注于建立一个强大的、记录齐全的软件套件，允许广泛的人员进行视频马赛克。所提出的处理方法也将同样适用于已收集并保存在众多海洋学机构档案中以及深潜器系统过去用户的大量视频数据。为了测试马赛克系统的近实时应用，PI 建议在即将进行的两次巡航期间在海上构建视频马赛克。 PI 组建了一个多学科科学家小组来测试镶嵌系统，并将其应用于与大洋中脊海洋地质和海洋生物学相关的问题，包括喷口流体化学的综合测量和连续潜水时喷口群落的采样与 EPR 国际空间站的阿尔文号潜水器。对近实时和遗留马赛克的岸上分析将用于帮助解释过去十年中多次访问的 EPR 喷口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 ISS 开发的 GIS 中。
