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

项目标题：支持潜水器和水下机器人作业的地理参考视频马赛克的生成项目摘要私人投资公司建议为基于PC的计算机开发一个易于使用的软件包，该软件包专为从绝对或相对导航网络中操作的任何水下机器人获取的视频图像进行转换，并快速生成一组地理参考图像，然后可以直接在地理信息系统(GIS)中进行分层。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像通过航空照片或卫星图像观察陆上过程一样，定量地探索相对较大的海底区域。最初的方法是开发一种适合于高效处理深潜潜水器潜水视频图像的系统。他们的目标将是使用和改进由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程序。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马赛克。拟议的处理方法也同样适用于已经收集的大量视频数据，这些视频数据保存在许多海洋机构的档案中，以及以前使用过深潜器系统的用户。为了测试马赛克系统的近乎实时的应用，PI建议在即将到来的两次巡航期间在海上构建视频马赛克。PIS组建了一个多学科的科学家小组来测试镶嵌系统，并将其应用于与大洋中脊的海洋地质学和海洋生物学相关的问题，包括对喷口流体化学的综合测量，以及在EPR ISS与阿尔文号潜水器连续潜水时对喷口群落的采样。近实时和遗留马赛克的岸基分析将被用来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。与地理有关的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.
