Zenmuse L3 Worry-Free Plus Combo

Compatible with DJI Matrice 400, and requires the use of the Zenmuse L3 single gimbal connector. Please ensure that the gimbal connector is connected to the E1 port on the aircraft's underside. Otherwise mapping accuracy will be reduced.

290 m (center), 200 m (edge)@10% reflectivity, 2000 kHz, recommended operating altitude ≤ 50 m

400 m (center), 280 m (edge)@10% reflectivity, 1000 kHz, recommended operating altitude ≤ 100 m

700 m (center), 500 m (edge)@10% reflectivity, 350 kHz, recommended operating altitude ≤ 300 m

950 m (center), 650 m (edge)@10% reflectivity, 100 kHz, recommended operating altitude ≤ 500 m

1. Range Definition: The range is defined as the distance at which 50% of the emitted laser pulses are detected. If a laser beam hits more than one subject, the total laser transmitter power is split and the achievable range is reduced.

2. Test Conditions: 100 klx ambient light, within the central area of the FOV, using a flat subject with a size larger than the laser beam diameter, a perpendicular angle of incidence, and an atmospheric visibility of 23 km.

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

Hardware performance improvements:

1. Zenmuse L3 delivers enhanced LiDAR performance. When measured at the same distance, Zenmuse L3 produces a laser spot about one-fifth the size of L2 and supports up to 16 returns. This means much stronger penetration capability, greater range, and higher ranging accuracy.

2. The new dual 100MP RGB mapping camera system brings a horizontal FOV of up to 107°, compared to L2's 73.7°.

3. POS accuracy is improved to 0.02° for heading, and 0.01° for roll and pitch.

Accuracy and efficiency improvements:

1. Zenmuse L3's vertical accuracy is better than 3 cm at 120m altitude, better than 5 cm at 300 m, and better than 10 cm at 500 m. The point cloud thickness produced by Zenmuse L3 is only half that of Zenmuse L2, supporting advanced analysis and high-accuracy applications.

2. With a smaller laser spot and higher single-pulse energy, Zenmuse L3 offers superior penetration capability. In terrain mapping and similar applications, it captures more ground points with greater completeness, significantly improving the accuracy and integrity of terrain data for precise surface fitting and reconstruction.

3. When mounted on DJI Matrice 400, Zenmuse L3 delivers outstanding efficiency. At a flight altitude of 300 m, a single flight can cover up to 10 km², enabling up to 100 km² of daily coverage.

The dual RGB mapping camera system expands the horizontal FOV to 107°, enabling each acquisition to cover a broader area. Even with a 20% LiDAR side overlap ratio, you can capture data for both digital orthophoto maps (DOM) and digital elevation models (DEM) in a single flight, thereby greatly improving operational efficiency.

It is recommended to use the CFexpress™ Type B memory card (1 TB) that comes with Zenmuse L3. This card is specifically optimized for the unique storage requirements of L3's point cloud data, images, and calibration files, ensuring ideal write speed, power efficiency, and file management.

Using a non-bundled CFexpress™ card may result in lower write speed or less efficient power management, which could lead to frame drops during operational file storage, thus affecting the accuracy of the results. When a non-bundled card is inserted, the app will display a warning message.

Zenmuse L3 can collect data covering an area of up to 10 km² in a single flight, enabling up to 100 km² of mapping per day.

When paired with DJI Matrice 400, Zenmuse L3 can achieve a daily mapping coverage of up to 100 km² (flat terrain, 300m nadir flight altitude, 20% side overlap, 17m/s flight speed, and a total effective flight time of 6 hours).

At 120m Flight Altitude:<br>Vertical Accuracy: 3 cm (RMSE)

Horizontal Accuracy: 4 cm (RMSE)

At 150m Flight Altitude:

Vertical Accuracy: 3.5 cm (RMSE)

Horizontal Accuracy: 5 cm (RMSE)

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.

Yes. After the operation, you can select real-time point cloud results in DJI Pilot 2 and upload them to the relevant project in DJI FlightHub 2 for emergency decision-making.

DJI Matrice 400 supports Real-Time Follow at altitudes from 30 to 300 m.

Point cloud processing for Zenmuse L3 is a free feature in DJI Terra. Advanced functions, such as point cloud accuracy optimization and generating other deliverables, are also free of charge.

This pricing information is based on DJI Terra V5.1.0. Whether subsequent updated functions will be charged is subject to the release notes at the time of publication.
