Autonomous Acoustic Ground Discrimination System for Seagrass Characterisation

无人地面交通工具(USVs)的早期设计者、建造者和运营者--HyhSurv无人调查(英国)有限公司与普利茅斯大学合作开发了一种新的紧密集成的机器人调查平台，该平台采用了新的声学地面识别系统(AGDS)，将针对海草草甸的变革性非侵入性、低影响和经济的监测解决方案交到保护机构手中。该项目将在普利茅斯大学现有研究的基础上，开发从传感器和嵌入式车辆组件到基于云的数据托管解决方案，该解决方案针对海草测绘进行了优化提供了复查之间的经济变化比较模型。处理解决方案将包括开发和培训新的机器学习算法来对沉水植物进行分类。该项目提供了超过43天的水上验证和测试，包括供主要利益相关者自然英格兰(解决方案测试者)、西南湖泊信托基金和国家海洋学中心审查的技术演示。开发该解决方案是为了提供一种新技术和新能力，以应对未来保护和恢复全球海草栖息地的需求，推动诸如蓝碳固存、海洋生物多样性保护等好处，并为渔业和海洋食品来源的安全创造条件。

HydroSurv Unmanned Survey (UK) Ltd, (_HydroSurv_), an early-stage impact-focused designer, builder and operator of Uncrewed Surface Vehicles (USVs) is collaborating with the University of Plymouth to develop a new tightly-integrated robotic survey platform that features a new Acoustic Ground Discrimination System (AGDS) to put a transformative non-invasive, low-impact and economic monitoring solution for seagrass meadows in the hands of conservation bodies.Building upon the existing research performed by University of Plymouth, the project will develop an end-to-end solution from the sensor and embedded vehicle components to a cloud-based data-hosting solution optimised for seagrass mapping, providing an economic change comparison modelling between resurveys. The processing solution will involve developing and training new machine-learning algorithms to classify submerged aquatic vegetation.The project provides more than 43 days of on-water validation and testing, including technology demonstrations for review by key stakeholders Natural England (solution tester), South West Lakes Trust and the National Oceanography Centre.The solution is developed to provide a new technology and a new capability to respond to future needs to protect and restore our seagrass habitats around the globe, driving benefits such as blue carbon sequestration, protection of marine biodiversity and creating the conditions for security of fisheries and ocean food sources.
