System Performance
Detection Range
450 m at 50 % reflectance, 0 klx
250 m at 10 % reflectance, 100 klx
Typical data. Measured with a flat target larger than the laser beam diameter, a vertical 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 strikes more than one target, the total laser transmission power is shared, reducing the achievable range. The maximum detection range is 500 m.
Point Cloud Rate
Single Return: Up to 240,000 points/s
Multiple Returns: Up to 1,200,000 points/s
System Accuracy
Horizontal: 5 cm at 150 m
Vertical: 4 cm at 150 m
Measured under the following conditions in a DJI laboratory environment: Zenmuse L2 mounted on Matrice 350 RTK and powered on. Flight route planning using DJI Pilot 2 Area Route with IMU calibration enabled. Repeated scanning with RTK in FIX status. The relative altitude was set to 150 m, flight speed to 15 m/s, gimbal tilt to -90°, and each straight flight segment of the route was less than 1500 m. The field contained objects with obvious angular features and used exposed control points on hard ground matching the diffuse reflection model. DJI Terra was used for post-processing with precision optimization for point clouds enabled. Under the same conditions, if precision optimization for point clouds is not enabled, the vertical accuracy is 4 cm, and the horizontal accuracy is 8 cm.
