Description
High-Precision Aerial LiDAR System
The DJI Zenmuse L2 is an integrated geospatial data acquisition system. It combines frame LiDAR technology, a high-accuracy IMU system, and a 4/3 CMOS RGB mapping camera. This system is designed to provide precise and efficient data collection capabilities when used with DJI flight platforms, particularly when integrated with DJI Terra software. The Zenmuse L2 offers high vertical and horizontal accuracy of 4 cm and 5 cm, respectively, covering a substantial 2.5 km² area in a single flight.
It features exceptional penetration capabilities, smaller laser spots than its predecessor, and supports up to 5 returns. With a frame-based design and improved IMU system, it ensures high-precision mapping, making it suitable for various applications, including land surveying, electricity management, forestry, infrastructure management, and more. Users can easily process point cloud data and achieve accurate geospatial results, enhancing overall operational efficiency.
| RGB Camera | Maximum Returns | System Accuracy | Detection Range |
|---|---|---|---|
| 20 MP, 4/3 CMOS | 5 | 5 CM Horizontal, 4 CM Vertical (150 m AGL) | 250 m @ 10% Reflectivity |

Comprehensive LiDAR Solution
With its robust hardware support, the L2 system excels at conducting precise scans of intricate subjects over extended distances, facilitating faster point cloud acquisition. During operations, users can conveniently preview, playback, and process point cloud models on-site, accompanied by Task Quality Reports generated by DJI Terra. This holistic solution simplifies the process, enhancing overall efficiency and enabling users to achieve high-precision point cloud results with streamlined post-processing.
Elevated Precision Levels
By combining GNSS technology with a highly accurate self-developed IMU, this solution achieves vertical accuracy of 4 cm and horizontal accuracy of 5 cm.
Exceptional Operational Efficiency
From the moment it’s powered on, the L2 system swiftly collects both geospatial and RGB data, covering a wide 2.5 km² area in a single flight.
Intuitive User Experience
In conjunction with the Matrice 350 RTK and DJI Terra, the L2 system provides a turnkey solution that is remarkably user-friendly, reducing the operational learning curve.
Expanded Detection Range by 30%
The L2 system offers impressive detection capabilities, ranging from 250 m at 10% reflectivity and 100 klx to 450 m at 50% reflectivity with 0 klx. This extended range enables a typical operational altitude increase of up to 120 m, significantly enhancing operational safety and efficiency.
Reduced Laser Spot Size, Enhanced Point Cloud Density
Featuring a smaller spot size of 4×12 cm @ 100 m — one-fifth the size of its predecessor — the L2 detects smaller objects with greater detail and penetrates denser vegetation, resulting in more accurate digital elevation models (DEM).
Support 5 Returns
In densely vegetated environments, the L2 can effectively capture more ground points concealed beneath foliage, enhancing terrain accuracy and surface detail.
Point Cloud Rate: 240,000 pts/s
Operating in both single and multiple return modes, the L2 achieves a maximum point cloud emission rate of 240,000 points per second, capturing more extensive datasets within shorter flight durations.
Two Versatile Scanning Modes
The L2 supports two scanning modes: Repetitive and Non-Repetitive. Repetitive mode delivers uniform, high-precision mapping, while Non-Repetitive mode enhances penetration for capturing complex structures such as power lines and dense forestry.
Innovative Frame-Based Design
The frame-based design delivers an effective point cloud data rate of up to 100%, complemented by a three-axis gimbal. This integration allows the L2 to adapt to diverse aerial surveying scenarios with unmatched precision and stability.
