High-Precision Aerial LiDAR System

ZENMUSE L2

Powerful Range, Elevated Precision

Zenmuse L2 integrates frame LiDAR, a self-developed high-accuracy IMU system, and a 4/3 CMOS RGB mapping camera, providing DJI flight platforms with more precise, efficient, and reliable geospatial data acquisition. When used with DJI Terra, it delivers a turnkey solution for 3D data collection and high-accuracy post-processing.

ZENMUSE L2

Integrated LiDAR Solution

Supported by its powerful hardware, L2 can allow for a precise scan of complex subjects within an extended range and faster point cloud acquisition. During operations, users can preview, playback, and process point cloud models on-site, with Task Quality Reports generated by DJI Terra, offering a simple, one-stop solution to improve overall efficiency. This enables users to achieve high-precision point cloud results with one-stop post-processing.

High-Level Precision

By combining GNSS and a high-accuracy self-developed IMU, this solution achieves 4cm vertical accuracy and 5cm horizontal accuracy.

Exceptional Efficiency

It’s ready for work as soon as it’s powered on and can collect both geospatial and RGB data from a 2.5km2 area in a single flight.

Intuitive Operation

In conjunction with Matrice 350 RTK and DJI Terra, L2 offers a turnkey solution that is simple to use, lowering the operational threshold.

ZENMUSE L2

30% Detection Range Increase

L2 can detect from 250 meters at 10% reflectivity and 100 klx, and up to 450 meters at 50% reflectivity and 0 klx. The typical operational altitude now extends up to 120 meters, notably enhancing operational safety and efficiency.

Smaller Laser Spots, Denser Point Clouds

With a reduced spot size of 4×12 cm @100m, only a fifth of that of L1, L2 not only detects smaller objects with more details, but can also penetrate denser vegetation, generating more accurate digital elevation models (DEM).

Supports 5 Returns

In densely vegetated areas, L2 can capture more ground points beneath the foliage.

Effective Point Cloud Rate: 240,000 pts/s

In both single and multiple return modes, L2 can reach a max point cloud emission rate of 240,000 points per second, allowing the acquisition of more point cloud data in a given time frame.

Two Scanning Modes

L2 supports two scanning modes, offering flexibility for users based on their task demands. In repetitive scanning mode, L2’s LiDAR can achieve more uniform and accurate point clouds while meeting high-precision mapping requirements. In non-repetitive scanning mode, it offers deeper penetration for more structural information, making it suitable for power line inspection, forestry surveying, and other scenarios.

Frame-based Design

The frame-based design results in an effective point cloud data rate of up to 100%. Together with a three-axis gimbal, it brings more possibilities to surveying scenarios.

High-Accuracy IMU System

Improved Accuracy

The high-accuracy self-developed IMU system, combined with the drone’s RTK positioning system for data fusion during post-processing. Gives L2 access to highly accurate absolute position, speed, and attitude information. In addition, the IMU system’s enhanced environmental adaptability improves the operational reliability and precision of L2.

Yaw Accuracy

Real-time: 0.2°, post-processing: 0.05°

Pitch/Roll Accuracy

Real-time 0.05°, post-processing 0.025°

No IMU Warm-up

The performance of the IMU system has been significantly enhanced, and it is ready for use the moment it’s powered on. And, the accompanying drone is ready to begin tasks immediately once the RTK is in FIX status, delivering an optimized in-the-field experience.

Enhanced Operational Experience with ZENMUSE L2

 

Diverse Flight Route Types

Supports Waypoint, Area, and Linear Route types, for handling surveying tasks in a variety of environments.

Point Cloud LiveView

During operation, DJI Pilot 2 supports three display modes – RGB, point cloud, and point cloud/RGB side-by-side display, presenting operational results in an intuitive way. Activating RNG (Laser Rangefinder) enables access to the distance information between the LiDAR module and the object in the center of the FOV, enhancing flight safety. It also supports four real-time point cloud coloring modes – Reflectivity, Height, Distance, and RGB.

Point Cloud Model Playback and Merging

After the operation, the 3D point cloud model can be viewed directly in the album. 3D Point cloud models of multiple flights can also be merged, enabling on-site decision-making regarding operational quality.

Auto-Generated Task Quality Report

After point cloud data collection, the DJI Pilot 2 app will automatically generate a Task Quality Report so that operators can check operational results in real-time and on-site, making fieldwork more responsive and worry-free.

PPK Solution

In complex operational environments, users can set up RTK base stations before the operation to preemptively avoid the loss of RTK data due to interference, video transmission disconnection, or other issues. After the operation, import original files into DJI Terra to use the PPK (post-processing kinematic) process to rebuild high-precision models.

One-Click Processing on DJI Terra

Achieve efficient and reliable one-stop post-processing when importing point cloud data into DJI Terra. Generate a standard-format 3D point cloud model with just a click after point cloud trajectory calculation and accuracy optimisation. Upon ground point classification, using Ground Point Type, a DEM can be output. Point cloud quality can be analysed with the Accuracy Control and Check function.

Application Scenarios

In coordination with DJI Enterprise flight platforms and DJI Terra, Zenmuse L2 can be applied to land surveying and mapping, electricity, forestry, and infrastructure management, as well as other scenarios.

      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.
