2G Robotics and Sonardyne Collaborate on Underwater Dynamic Laser Mapping Solution

海底科技公司，2G Robotics188asia备用网址 Inc.和Sonardyne International Ltd，英国。已宣布已签订正式的合作协议。这两个组织正在合作开发和推广动态水下激光映射解决方案，这显着减少了调查海底地点和海上结构所需的时间。

The new agreement centres on the integration of Sonardyne’s acoustically-aided inertial navigation system for underwater vehicles, SPRINT-Mapper, with 2G Robotics’ ULS-500 PRO dynamic underwater laser scanner. Projects conducted over the past six months have shown that combining the high resolution afforded by the 2G Robotics’ laser scanner, with an unprecedented level of practical positioning accuracy, produces a complete solution for fast and efficient dynamic laser scanning projects. These include archaeological surveys, pipeline and free span inspections, structural integrity monitoring and one of the most demanding of all survey tasks, pipeline metrology.

Until now, attempts at mapping from dynamic platforms have largely involved multi-beam imaging sonars being fitted to ROVs, AUVs and manned submersibles equipped with inertial, Doppler, acoustic positioning and depth instrumentation. As a result of their mobility, large areas can be quickly surveyed but this approach typically only achieves up to 10 cm relative accuracy - effectively ruling out applications like metrology which require centimetre or better accuracy.

这项技术使用2 g机器人极限状态- 500PRO laser scanner fitted to an underwater vehicle to capture high density point clouds of subsea assets and environments. As the vehicle moves around the site, the SPRINT-Mapper hardware, also fitted to the vehicle, simultaneously collects raw acoustic and inertial navigation data. On completion of the survey, the raw navigational data is post-processed and merged with the laser data to produce a georeferenced 3D point cloud from which centimetric level or better engineering measurements can be taken.

By adopting a dynamic platform such as an ROV navigated using SPRINT-Mapper, the high-resolution laser data is no longer constrained by a stationary deployment location - this breakthrough in underwater mapping means an entire site can now be surveyed quickly and with the flexibility to overcome adverse conditions such as visibility. As the underwater vehicle does not have to come into contact with the seabed at the survey site, it can move to scan any target of interest from a variety of perspectives.

这种新的伙伴关系是客户寻求雇用这种强大的调查技术的重要发展。通过该协议，2G机器人和Sonardyne以及其分销商现在可以为动态扫描提供完整的包装 - 有效地消除了最终客户所面临的任何集成挑战。

Sonardyne施工调查的全球商业经理Edward Moller表示，“我们在最近几个月内收集了在项目的后期图像中可见的细节水平，必须被认为是相信的;小螺栓孔，单个链条，海洋生长甚至涂漆标记都可以清楚地看到。在广域海底可视化方面，这是一个真正的游戏变换器。“2G Robotics的产品开发经理Chris Gilson表示，“新的伙伴关系在集成多个系统时，最多的海底客户面临的复杂性。我们技术集成提供的细节允许客户不仅捕获卓越的数据，而且更有效地竞争项目。“
