DJI Zenmuse L1 LiDAR System

Description

A Lidar + RGB Solution for Aerial Surveying

The Zenmuse L1 integrates a Livox Lidar module, a high-accuracy IMU, and a camera with a 1-inch CMOS on a 3-axis stabilized gimbal. When used with Matrice 300 RTK and DJI Terra, the L1 forms a complete solution that gives you real-time 3D data throughout the day, efficiently capturing the details of complex structures and delivering highly accurate reconstructed models.

Use Cases

• Topographic Mapping – Quickly generate topographic maps using accurate digital elevation models.
• AEC and Surveying – Manage the full project lifecycle using highly accurate point clouds and 3D models.
• Emergency Response – Any time of the day, gather critical insights in real-time using true-color point clouds.
• Law Enforcement – Gain situational awareness and forensic Intel in real-time to make informed decisions on site.
• Energy and Infrastructure – Model sparse or complex structures in detail to manage them efficiently and safely.
• Agriculture and Forestry Management – Gain insight into vegetation density, area, stock volume, canopy width, and growth trends.

Ready When You Are

The IP54 rating allows the L1 to be operated in rainy or foggy environments.

The Lidar module’s active scanning method enables you to fly at night.

Exceptional Efficiency

Generate true-color point cloud models in real-time, or acquire 2 km2 of point cloud data in a single flight
^[1] using the Livox frame Lidar module with a 70° FOV and a visible light camera with a 1-inch sensor.

Point Cloud LiveView

Real-time point clouds provide immediate insights onsite, so operators are informed to make critical decisions quickly.

You can also verify fieldwork quality by checking point cloud data immediately after each flight.

One-stop Post-processing

DJI Terra fuses the IMU and GNSS data for point cloud and visible light calculations, in addition to conducting POS data calculations so you can effortlessly generate reconstructed models and accuracy reports.

Measurement and Annotation

Acquire and communicate critical dimensions on the point cloud model using measurements and annotations.^[4]

[1] Over 30 minutes, at a speed of 13 m/s, a flight altitude of 100 m, with a side overlap rate of 10%, point cloud density > 100 points/m2.
[2] The accuracy was measured after a 5-minute warm up, using Mapping Mission with Calibration Flight enabled in DJI Pilot, and with the RTK in FIX status. The relative altitude was set to 50 m, flight speed to 10 m/s, gimbal pitch to -90°, and each straight segment of the flight route was less than 1000 m. DJI Terra was used for post-processing.
[3] In operations with two or three returns, the point rate is 480,000 pts/s
