What is the surveying and mapping accuracy of Zenmuse L2?

The surveying and mapping accuracy of the DJI Zenmuse L2 is:

• Horizontal accuracy: 5 cm
• Vertical accuracy: 4 cm

Measured under the following conditions in a DJI laboratory environment:

• The DJI Zenmuse L2 mounted on a Matrice 350 RTK and powered up.
• Using DJI Pilot 2’s Area Route to plan the flight route (with Calibrate IMU enabled).
• Using repetitive scanning with the RTK in the FIX status.
• The relative altitude was set to 150 m, flight speed to 15 m/s, gimbal pitch to -90°, and each straight segment of the flight route was less than 1500 m.
• The field contained objects with obvious angular features, and used exposed hard ground check points that conformed to the diffuse reflection model.
• DJI Terra was used for post-processing with Optimize Point Cloud Accuracy enabled.
• Under the same conditions with Optimise Point Cloud Accuracy not enabled, the vertical accuracy is 4 cm and the horizontal accuracy is 8 cm.
