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:
Generate point clouds in real-time.
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.
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.
LiDAR sensor has a range of uses.
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:
Operators can use the DJI ecosystem for an end-to-end LiDAR surveying workflow. This involves the M300 RTK, the L1 sensor, DJI Terra, and the DJI Pilot app.
Data Acquisition: Plan mission using DJI Pilot app, with a range of mission options available. Make sure the M300 RTK is connected to RTK network, otherwise DJI Terra will not post-process the captured data.
Data Process: In DJI Terra ‘Aerial Photography’ task, select the mapping scene as ‘LiDAR post-processing’, and then select the source folder containing LiDAR IMU and Inertial Navigation Data to start data processing. If the selected folder contains visible light photos, the generated point-cloud file is a visible light point cloud.
The L1 has an IP54 rating according to the IEC60529 standard. This means that it is protected against solid objects over 1mm in size and against water splashed from all directions. The protection level is not permanent however and will decrease over time due to device wear.
To ensure the highest levels of protection:
The L1 is compatible with the M300 RTK. Before using, please upgrade the firmware of the drone and remote controller to the latest version.
The L1 currently supports only the Android version of the DJI Pilot App.
The camera requires a MicroSD card with Class 10 or higher transmission speed or rated UHS-1 , with up to 256 GB supported.
In Non-repetitive Scanning mode, the FOV is 70.4°x77.2°.
In Repetitive Scanning mode, the FOV is 70.4°x4.5°.
The maximum measuring range of the L1 is 190m@10%, 100klx ; 450m@80%, 0klx.
The recommended typical working height is 50m-120m.
The L1 provides three scanning frequencies: one/two returns: 80K/s, 160K/s, and 240K/s; three returns: 80K/s, 240K/s.
The L1 has two scanning modes: Non-repetitive Scanning mode and Repetitive Scanning mode.
The L1 supports 3 types of returns:
The L1 collects point cloud models based on RTK and displays the collected models on Pilot in real time.
The following features are supported:
For high-accuracy post-processed modeling, you can import the data from the SD card into DJI Terra with one click. This will generate a colorized point cloud model with high-accuracy PPK-IMU position and orientation calculation supported.
The L1 supports the following model reconstruction formats:Point cloud formats: PNTS, LAS, PLY, PCD and S3MB
The L1 currently supports Mapping, Linear Flight Mission, Oblique and Waypoint.
In typical operating scenarios, the IMU accuracy of the L1 is 0.025°(roll/pitch)/0.15°(yaw). The accuracy was measured under the following conditions in a DJI laboratory environment: after a 5-minute warm up, using Mapping Mission with Calibration Flight enabled in DJI Pilot, and with the RTK in FIX status. The relative altitude was set to 50 m, flight speed to 10 m/s, gimbal pitch to -90°, and each straight segment of the flight route was less than 1000 m. DJI Terra was used for post-processing.
The vision sensor provides altitude data. This means that if the GNSS signal temporarily fails, the aircraft’s accuracy will not be affected for up to 60 seconds. Support coming soon.
The RGB camera of the L1 provides basic functions for taking photos and recording videos and provides real-time color information for the point cloud data during the scanning process. This allows the L1 to output true color point clouds and reality models.
Note that Lidar scanning and video recording cannot work simultaneously.
The vertical accuracy of the L1 can reach 5 cm and the horizontal accuracy can reach 10 cm. The accuracy was measured under the following conditions in a DJI laboratory environment: after a 5-minute warm up, using Mapping Mission with Calibration Flight enabled in DJI Pilot, and with the RTK in FIX status. The relative altitude was set to 50 m, flight speed to 10 m/s, gimbal pitch to -90°, and each straight segment of the flight route was less than 1000 m. DJI Terra was used for post-processing.
The Lidar module of the L1 has active detection capability which can scan terrain to collect point clouds during nighttime or other low light conditions.
The Lidar module of the L1 adopts an Advanced Frame Scanning mode. This ensures that all point clouds collected are valid point cloud data.
At a flight height of 100 m and a velocity of 13 m/s, a single flight with the M300 RTK and the L1 can collect data covering an area of 2 km2.
The L1 can be widely used in multiple scenarios including:
The L1 can be mounted on the right downward gimbal port (when facing the drone) of the M300 RTK. Currently, only suppot single gimbal mode.
An upgraded flagship drone platform, the Matrice 350 RTK sets a new benchmark for the industry. This next-generation drone platform features an all-new video transmission system and control experience, a more efficient battery system, and more comprehensive safety features, as well as robust payload and expansion capabilities. It is fully powered to inject innovative strength into any aerial operation.
A safe, efficient, and accurate way to obtain 3D nuclear radiation dose rate distribution. Assess the scene from a safer distance.
Extra-lightweight GPR system, suitable for medium-sized drones like DJI M300 RTK.
Comes with 3x sets of dipoles for the 300, 150, and 100 MHz.
Utilizes Real Time Sampling (RTS) with high hardware stacking, delivering high-resolution low-noise data.
Laser Falcon is sensitive only to methane, so no false readings of other gases are possible. It is a class 3R eye-safe laser.
The concept is based on Infrared Absorption Spectroscopy. The laser emits light (spectral range of 1,65 μm), which reflects back and is captured by the sensor. The outgoing and incoming signals are compared with the built-in reference cell. If methane is present along the laser path, the laser light is partially absorbed. An algorithm calculates the gas concentration in ppm×m (parts per million multiplied by meter). The value is instantly transferred to the remote control (RC) of the drone pilot and to UgCS software.
