DJI Zenmuse L2 for a new era of 3D data acquisition


The DJI Zenmuse L2 is an advanced LiDAR system, building upon the success of its predecessor, the Zenmuse L1. It offers improved features, including an enhanced RGB camera, upgraded LiDAR module, and enhanced accuracy, making it a valuable tool for professionals.


Increased hardware power and efficiency

The Zenmuse L2 leverages aerial LiDAR technology to provide efficient and precise 3D data acquisition for professionals in various fields, such as land surveying, mapping, electricity inspection, forestry, and infrastructure management.

It significantly reduces workload and field measurement time while improving detection efficiency.


Perfect for DJI Matrice 300/350 RTK

The Zenmuse L2 incorporates a high-accuracy IMU system and integrates seamlessly with DJI Matrice 300 RTK and Matrice 350 RTK drones.

This combination delivers accurate and efficient data collection while enhancing in-the-field experiences with immediate readiness and high precision.


Improved detection range and safety

With a 30% increase in detection range compared to its predecessor, the Zenmuse L2 enhances operational safety and efficiency. It detects objects from greater distances, has a reduced spot size for more detailed data, and supports multiple return modes for enhanced data acquisition.


Enhanced imaging and reduced operational costs

The Zenmuse L2 features an upgraded RGB mapping camera with improved imaging and colorized point cloud details.

It offers reduced photo intervals, extended shutter life, and the ability to capture photos and videos, even when point cloud data isn't necessary.


Software for control and data processing

DJI Pilot 2 software offers various display modes and real-time monitoring options, enhancing control during operation. It provides access to distance information and supports real-time point cloud coloring.

Additionally, it can generate route operation quality reports and offers point cloud processing.


One tool, multiple use cases

The Zenmuse L2, in combination with DJI Matrice 300 RTK or Matrice 350 RTK drones and DJI Terra software, is suitable for various industries. It excels in applications such as topographic mapping, forestry, and electricity inspection, offering efficient data collection and analysis for diverse scenarios.


More protection with DJI Care Enterprise

This DJI Zenmuse L2 Lidar Camera with Care Enterprise Basic package comes with 1-year coverage of DJI Care Enterprise Basic Plan.

The plan includes water damage coverage, 2 low-cost replacements, DJI Care Express, and free two-way shipping.


In summary, the DJI Zenmuse L2 represents a significant advancement in LiDAR technology, building on the success of its predecessor, the Zenmuse L1. Its enhanced features, including an upgraded RGB camera, improved LiDAR module, and higher accuracy, make it an invaluable tool for professionals across multiple industries.

System Performance

Detection Range
- 450m @50% reflectivity, 0 klx
- 250m @10% reflectivity, 100 klx

- Typical 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/s
- Multiple returns: max. 1,200,000 pts/s

System Accuracy
- Horizontal: 5 cm @ 150 m
- Vertical: 4 cm @ 150 m

- Measured 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.
