Efficient, Accurate, Cost-effective
The DJI Zenmuse L1 is a cost-efficient and easy to use enterprise aerial LiDAR payload, engineered for DJI’s flagship commercial drone, the M300 RTK.
The L1 integrates a Livox sensor, high-precision IMU, a one-inch 20MP CMOS visual camera with mechanical shutter, and 3-axis stabilised gimbal system.
Combine it with the M300 RTK and the mapping software DJI Terra for a highly-efficient all-in-one aerial LiDAR solution to obtain 3D point clouds for high accuracy and detailed reconstruction.
The L1 can be used across a range of industry verticals, such as energy, AEC, forestry, public safety, and more.
The highlights of the L1 are:
- All-in-one Solution: Integrates a Lidar module, an RGB camera, and a high-accuracy IMU.
- High Accuracy: Vertical – 5cm; Horizontal – 10cm (with 50m flight height).
- Efficient: Cover 2km² in a single flight (flight velocity 10 m/s, flight height 100m, side overlap ratio 20%).
- High Density Point Cloud: 240,000 effective points/s.
- Multiple Returns: Support three returns (Dual and Triple returns, point cloud density 480,000 pts/sec).
- Measurement Range: 450m maximum (80% reflectivity 0 klx).
- Real-time Point Cloud View: Able to display and measure point clouds in real time.
- Weather Resistant: IP44 rating, enabling operators to collect data in rainy or foggy environments.
- DJI Ecosystem: Use DJI Terra for post-processing data.
Streamline LiDAR Missions
The Zenmuse L1 integrates a powerful and ultra-lightweight Livox Lidar module with a 70° FOV, a high-accuracy IMU, and a 20-megapixel camera with a 1-inch CMOS sensor.
The Zenmuse L1 can generate true-color point cloud models in real-time, or acquire a vast area (up to 2km²) of point cloud data in a single flight.
With a Point Rate of 240.000 points per second and a detection range of 450 meters, the ease and speed of capturing quality Lidar data is unprecedented.
The module supports both Line Scan Mode and Non-repetitive Scanning Mode, a unique technology developed by Livox.
This will provide full coverage of the area of interest in a very short amount of time, and allows the sensor to capture data in any direction, instead of along a defined plane.
The Zenmuse L1 Lidar solution can easily penetrate vegetation canopies and foliage.
DJI L1 Additional Features
Payload Health Management System: Built into the DJI Pilot app, the Payload Health Management System records the total use time of the DJI L1, as well as the number of rotation times, error logs, and product maintenance suggestions.
Real-time Awareness Flight: The LiDAR sensor can obtain the aircraft’s height above the ground in real-time and perform a terrain awareness flight to ensure data quality and flight safety.
Accuracy Report: After the flight, DJI Pilot will generate an inspection report, view the quality of the point-cloud data, the photo position, number of photos, and the RTK status, so the pilot can confirm the quality of the data on-site.
Generate Accurate Models And Reconstructions
The DJI L1 is aimed at commercial drone users who are seeking high-accuracy aerial surveying solutions.
The LiDAR sensor can empower clients in energy, AEC, public safety, architecture/heritage, and forestry management.
The L1 is ideal for the following scenarios:
- Topographic Survey: Collect elevation data in a dense vegetation field. The L1 is able to extract Digital Elevation Models (DEM) and Digital Surface Models (DSM).
- Infrastructure Reconstruction: Reconstruct highly-detailed structures such as power lines, and oil and gas pipelines to reduce manned operations – improving efficiency and increasing safety.
- Forestry: Due to the multi-echo capability of the DJI L1, the elevation data in dense forest fields can be easily generated and extracted into DEM and DSM.
- Emergency Mapping Survey: The DJI L1 is capable of capturing real-time, true colour point-cloud models. This provides up to date information for emergency response teams. The IP44-rated L1 can also operate in rainy/foggy conditions, as well as low-light scenarios.
