What is the protection level of the Zenmuse L1?

The L1 has an IP54 rating according to the IEC60529 standard. This means that it is protected against solid objects over 1mm in size and against water splashed from all directions. The protection level is not permanent however and will decrease over time due to device wear.

To ensure the highest levels of protection:

Before installing, make sure that the interface and surface of the gimbal are dry;
Before use, make sure that the gimbal is firmly installed on the drone and the SD card protective cap is clean, free of foreign objects, and closed;
Before opening the SD card protective cap, wipe the surface of the drone clean.

What is the IMU accuracy of the L1?

In typical operating scenarios, the IMU accuracy of the L1 is 0.025°(roll/pitch)/0.15°(yaw). 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.

What is the L1’s auxiliary vision sensor used for?

The vision sensor provides altitude data. This means that if the GNSS signal temporarily fails, the aircraft’s accuracy will not be affected for up to 60 seconds. Support coming soon.

What is the L1’s RGB camera used for?

The RGB camera of the L1 provides basic functions for taking photos and recording videos and provides real-time color information for the point cloud data during the scanning process. This allows the L1 to output true color point clouds and reality models.
Note that Lidar scanning and video recording cannot work simultaneously.

The vertical accuracy of the L1 can reach 5 cm and the horizontal accuracy can reach 10 cm. 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.

Can the L1 work at night?

The Lidar module of the L1 has active detection capability which can scan terrain to collect point clouds during nighttime or other low light conditions.
