Zenmuse L1 Gimbal Camera

Zenmuse L1 Gimbal Camera. Instant Clarity. Superior Accuracy. 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.

Features

Exceptional Efficiency

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

Unparalleled Accuracy

Render centimeter-accurate reconstructions thanks to the high-accuracy IMU, a vision sensor for positioning accuracy, and the incorporation of GNSS data.

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.

Notes

1. The accuracy was measured under the following conditions in a DJI laboratory environment: 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.
2. Measured in an environment of 25℃ with a target (80% reflectivity) 100 meters away. The result may vary under different test conditions.
3. The recommended microSD cards may be updated in future. Visit the DJI official website for the latest information.
