IP Rating IP54 Supported Aircraft Matrice 300 RTK (requires DJI RC Plus)Matrice 350 RTK Storage Temperature -20° to 60° C (-4° to 140° F) General Operating Temperature -20° to 50° C (-4° to 122° F) System Performance Detection Range 450m @50% reflectivity, 0 klx250m @10% reflectivity, 100 klxTypical data. Measured using a flat subject with a size larger than the laser beam diameter, perpendicular angle of incidence, and an atmospheric visibility of 23 km. In low-light environments, the laser beams can achieve the optimal detection range. If a laser beam hits more than one subject, the total laser transmitter power is split, and the achievable range is reduced. The maximum detection range is 500 m. Point Cloud Rate Single return: max. 240,000 pts/sMultiple returns: max. 1,200,000 pts/s System Accuracy Horizontal: 5 cm @ 150 mVertical: 4 cm @ 150 mMeasured under the following conditions in a DJI laboratory environment: 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 Optimize Point Cloud Accuracy not enabled, the vertical accuracy is 4 cm and the horizontal accuracy is 8 cm. Real-Time Point Cloud Coloring Coding Reflectivity, Height, Distance, RGB LiDAR Ranging Accuracy (RMS 1σ) 2 cm @ 150 mMeasured in an environment of 25° C (77° F) with a subject of 80% reflectivity at a distance of 150 m. The actual environment may differ from the testing environment. The figure listed is for reference only.
