DJI Zemuse L1

What is the DJI Zemuse L1 good for?

Designed as an integrated end-to-end mapping solution, the Zenmuse L1 consists of a Livox Lidar module, a high-accuracy IMU, and a camera with a 1-inch CMOS on a 3-axis stabilized gimbal.

Capturing L1 point cloud data at 240,000 pts/s and generating point clouds in real-time with a detection range of 450 m (80% reflectivity) allows quick and easy capture of surface-level data unable to be delivered by photogrammetry alone.

The main purpose of the L1 is to generate precise 3D point cloud models with a focus on mapping projects.

The benefits of LIDAR are that it is designed to capture the 3D information inherently, as opposed to photogrammetry which relies on the identification of common points in images and triangulates the information to create a 3D model. Therefore, it doesn’t require additional processing to create the 3D depth information as it is captured in the data itself. The L1 can also map in low light as opposed to photogrammetry which requires good lighting plus a major benefit is that LIDAR is much better at penetrating foliage allowing it to gather data about the surface itself as opposed to relying on data from canopy level.

The L1 does also have a visual camera, which allows it to take images for photogrammetry alongside the LIDAR data which can help improve the accuracy of the overall data.

Who is it for?

The DJI Zenmuse L1 and the M300 make LIDAR technology easily accessible to surveyors without the complicated operation and workflow so often associated with LIDAR systems, opening up the technology to less experienced users.

With the quick and precise capture of data via LIDAR, which can be processed quickly and delivered at speed, the L1 is a great tool for public safety professionals who need an immediate understanding of an accident or disaster site. Enabling a much quicker delivery than photogrammetry, the L1 opens up many possibilities for such use cases.

For surveyors carrying out power line inspections, for example, LIDAR is a great solution as it allows precise capture of power lines and small features within the point cloud.
