DJI Zenmuse L3

DJI is proud to introduce the new high-integration aerial LiDAR and camera system Zenmuse L3, designed for professional mapping, infrastructure inspection, forestry, and industrial applications.

The L3 combines an advanced LiDAR module with an improved detection range, a high-performance RGB camera (possibly 4/3-inch or full-frame sensor), a built-in high-precision IMU, and a 3-axis stabilized gimbal.

Supports up to 5 (or more) laser returns and generates an even denser point cloud for penetration through vegetation and complex surfaces.
Significantly extended detection range (e.g., 300–500 m for low-reflectivity targets) and improved vertical and horizontal accuracy (approximately 2–3 cm vertical, 3–4 cm horizontal), suitable for 1:1000-scale topographic mapping or better.
Enhanced compatibility with Matrice RTK platforms and optimized workflow with DJI Terra software for seamless LiDAR data processing and photogrammetry.
Increased reliability: improved IMU calibration, wider operating temperature range, and reduced module weight for easier integration and deployment.
Ideal for large-scale mapping and survey missions — capable of covering extensive areas in one or two flights.
Expected availability: within the coming months through official DJI Enterprise dealers.

Key Features

1535nm long-range LiDAR sensor for high penetration and accuracy
Dual 100MP RGB mapping camera system
Up to 100 km² daily coverage under optimal conditions

Point Cloud System Accuracy

At 120m Flight Altitude:

At 300m Flight Altitude:
Vertical Accuracy 5 cm (RMSE)
Horizontal Accuracy: 7.5 cm (RMSE)

^{Measured under the following conditions in a DJI laboratory environment:}
^{1. The field contained objects with obvious angular features. DJI Matrice 400 was linked to a position-calibrated D-RTK 3 Multifunctional Station. The flight route was planned using DJI Pilot 2's Area Route (with Calibrate IMU enabled) with Linear scanning. The flight speed was set to 15 m/s, gimbal pitch to -90°, and each straight segment of the flight route was less than 3300 m.}
^{2. Using exposed hard ground checkpoints that conformed to the diffuse reflection model.}
^{3. DJI Terra was used for post-processing with Optimize Point Cloud Accuracy enabled.}

Point Cloud Thickness

1.2 cm@1σ (120m nadir flight altitude)
2 cm@1σ (300m nadir flight altitude)

^{Measured in Linear scanning mode, using check points on 80% reflectivity objects, with neither point cloud optimization nor downsampling enabled in DJI Terra. For 6σ, multiply the listed thickness by 6.}

Combined Horizontal FOV (Dual RGB Mapping Cameras)

107°

^{Composed by merging images from two cameras with a 45° optical axis angle between them.}

^{3. The maximum detection range is 900 m by default. For a longer range, contact DJI support or an authorized dealer.}
