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

项目名称：支持潜水器和水下航行器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，该软件包被定制为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。在开发这一软件时，我们希望使那些收集视频图像的人能够以通过航空照片或卫星图像观察陆基过程的同样方式，对相对较大的海底区域进行定量探索。最初的办法是开发一种适合于有效处理深潜器潜水视频图像的系统。他们的目标将是使用和完善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，以便随后的潜水和采样程序可以得到优化。他们将集中精力建立一个强大的，有良好记录的软件套件，将允许视频拼接的范围广泛的人员。拟议的处理方法也同样适用于已经收集的大量视频数据，这些数据存放在许多海洋学机构的档案中，并与深潜器系统的过去用户共享。为了测试马赛克系统的近实时应用，PI建议在即将到来的两次巡航中在海上构建视频马赛克。研究所召集了一个多学科科学家小组，以测试镶嵌系统，并将其应用于与大洋中脊的海洋地质学和海洋生物学有关的问题，包括在EPR国际空间站用潜水器Alvin连续潜水时对喷口流体化学进行综合测量和对喷口群落进行取样。将利用对海岸近实时和遗留马赛克的分析，帮助解释过去十年多次访问的EPR喷口的群落结构的时间变化。地理参照视频镶嵌图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.
