这Zenmuse L1is the first Lidar payload developed by DJI, integrating a Livox Lidar module, a high-accuracy IMU and a camera with a 1-inch CMOS on a 3-axis stabilized gimbal. The L1 delivers enhanced 3D data capture capability with a detection range of up to 450m, enabling the acquisition of up to 2 square kilometres of point cloud data in a single flight. It offers point cloud data capture with exceptional centimetre-level accuracy thanks to the high-precision IMU, vision sensor for positioning accuracy, plus GNSS data.
One of the benefits of this Lidar drone system is full integration with theDJI Matrice 300 RTKand theDJI Terra软件生态系统，因此无需投资第三方软件服务。这意味着更快，更轻松的后处理和兼容，完整的系统，以支持无人机lidar映射业务需求的完整套件。Zenmuse L1发布是DJI首次发布自己的LiDAR有效载荷，所有者和运营商可以对这种强大的新LIDAR解决方案充满信心，因为它得到了DJI对质量的承诺的支持。
Overcoming vegetation and terrain challenges with ease
Travis Le Moine，导演或Seiler Geodrones, is an authorized reseller of the L1 Lidar drone and a longtime partner of DJI. Seiler has over a decade of experience in providing professional measurement solutions to the geospatial industry, specializing in custom drone solutions. Le Moine recently tested theZenmuse L1在美国工程公司的空间技术集团经理Peter Ferretti上，高于植被的地形上方Baxter and Woodman. Le Moine was keen to deploy the L1 for its agility and its precise data collection. “It uses a 3600在世界上收集数据的圆形光束，这意味着它非常引导，因此可以收集精确的数据而不会过多噪音。”他指出。“这导致我们需要更少的时间来捕获数据，而在后期进行后期的时间更少，因此在准确性和节省时间方面，这里有明显的优势。”在此测试站点上，DJI无人机lidar映射系统提供的高准确性和敏捷性消除了对猜测的需求。
LIDARoffers significant benefits for challenging forest inventory that a surveyor would normally need to walk through. There is no longer the need to continually move the physical station and struggle to rely on GPS, which is less effective in heavy foliage. Le Moines noted the utility of theL1尽管植被茂密，但具有捕获准确数据的震动能力，比常规的摄影测量方法明显优势。Ferretti对L1能够穿透植被及其在项目上的快速周转时间的能力。他说：“它还能够到达无法使用常规测量的不可接受或不安全的区域。”因为L1有三个回报，每个激光脉冲都有多个机会，可以在地面上进行测量以捕获轮廓。
Insights from Indonesia
CEO ofHalo Robotics, Eli Moselle, also jumped at the chance to test out DJI’s newZenmuse L1payload with a team from Pertamina Geothermal Energy. Based in Jakarta, Indonesia, Halo Robotics is an authorized distributor of full drone solutions and services across all industries. The team conducted several flights using theL1结合Phantom 4 RTK和DJI Terra. “Post-processing took as little as two to three hours, and had a very straightforward workflow,” they reported. Moselle and his team were impressed with theL1’s suite of safety features and high precision accuracy, and the RGB values produced by the point clouds made the outputs easier to understand and more efficient to work with.
Where conventional systems involving photogrammetry data can be time-consuming and expensive, the Pertamina operations team found that the L1 demonstrated its capacity in surveying as effective, fast, cost-effective and safe. Moselle recommends theM300 RTK+ L1 Lidar solution as a high-quality, effective tool in helping companies generate spatial data, perfect for elevation mapping and land morphology analysis. In Pertamina, the L1 aerial Lidar sensor enabled data to be collected for pipeline and power structures. “So they could be maintained efficiently and safely, without any environmental impact,” explained Moselle.
Moselle’s team added: “With theL1, things that were almost impossible and could have not been done before have now become possible to do, greatly helping our operations.” TheL1ushers in a new era for aerial drone technology, delivering accuracy, productivity, cost and safety gains, and suitability across all kinds of projects, from geothermal drilling to power production and from vegetation mapping to power structures.
Real-time point clouds in all weather conditions
Using a payload with an active scanning method like theL1是在不利天气条件（如雨，雾，云和低光）中捕获数据的理想选择。这L1对于常规测量，例如地震或洪水之后，或在夜间在道路上工作的情况，可以部署在常规测量中的危险中，那里的环境对人类测量师不安全。DJI系统可以在多个应用程序中使用，例如，作为支持复杂地面消防或搜救工作的附加工具。功能强大的L1无人机激光映射系统非常坚固耐用，具有IP45保护。L1和M300一起呈现一个紧凑，稳定且高性能的系统。不可避免的是无人机使用的不可避免，无论操作员多么经验，因此，L1和M300的稳固性和可修复是可放心的，旨在承受各种天气状况，并具有实用，创新的功能。
的能力角度实时云是built into the L1, enabling operators to generate true-colour point cloud models on-site using a feature called LiveView. Le Moine explained the advantage this payload has over its competitors: “Another unique feature about the L1 system is that you can see the data in real time, whereas most don’t show you that at all, or if they do, it’s only on a basic level.” This feature arms operators with accurate data to inform critical decisions.
Easy to use, accessible and automated
During testing, the L1’s ease of use came into its own. “There’s an automatic control to turn on all the high-precision components, whereas other systems need to be initialized manually, and that the GPS and IMU (inertial measurement unit) functions are already written into the software. DJI have done a great job here in developing the product in this way, since they’ve listened to surveyors working in the field: the software is really well written, initializing in exactly the way the IMU needs to,” commented Le Moine. He described how the software processing is primarily automatic, and that bringing data into theDJI Terra softwareis as straightforward and simple as taking the files off the memory card and dropping them into the software. It is easy to see why DJI is the leader in the commercial drone market, with such high-quality, uncomplicated tools at attractive prices.
负担得起的价格和高投资回报率
由于价格合理的价格和非常好的价值，L1在成本方面是全方位的赢家。“大多数其他系统的昂贵几倍，但是L1has real-time data, is all integrated, has no incompatibility issues and competes against other systems that are several times more expensive,” Le Moine pointed out.Both Seiler and Baxter and Woodman agreed that the integration to the field software fit together well, reducing the need for additional third-party software, avoiding potential problems faced when the Lidar sensor functions separately from the drone. The launch of the L1 at such a high value-for-money price point means that it will actually be cheaper and more accessible for businesses to own the Lidar system, instead of renting it.
这Zenmuse L1LIDAR无人机系统设定了前进的空中LIDAR的新标准，其健康功能集，精度准确性，实时数据传递和舒适的使用易用性。它是紧凑，强大而准确的，使操作员能够毫不费力地在各种项目中生成重建的模型和准确的报告。Seiler说：“ L1提供了一些令人印象深刻的规格，以及时间和金钱方面的重要效率。”它将成为GIS专业人员必不可少的工具。要了解有关L1或购买该系统的更多信息，该系统于2021年初提供接触DJI Enterprisetoday.
