DJI Unveils Zenmuse L3: The First Long-Range, High-Precision Aerial LiDAR System

DJI, the global leader in civil drones and innovative camera technologies, has officially launched the Zenmuse L3, a state-of-the-art aerial LiDAR system. This innovative product marks a significant advancement in the field of aerial surveying, boasting a long-range LiDAR system that operates at 1,535 nm and reaches up to 950 meters, even on objects with just 10% reflectivity. This exceptional capability not only enhances precision but also expands visibility, making it an indispensable tool for various geospatial operations.

Features and Capabilities

The Zenmuse L3 is equipped with two 100 MP RGB mapping cameras that, along with its high-precision POS system, accelerate data acquisition, capable of covering an impressive area of up to 100 square kilometers per day. One of the outstanding features of the L3 is its ability to generate multiple mapping deliverables from a single flight, significantly optimizing operational efficiency.

Long-Range LiDAR Specifications

The Zenmuse L3 utilizes a high-precision LiDAR system that achieves a detection range of 950 meters at an adjustable pulse frequency of 100 kHz. Tested under ambient light conditions of 100 klx, it can detect objects with a mere 10% reflectivity. This internal LiDAR technology ensures high measurement repeatability, allowing for precise 5 mm measurements at distances of 150 m, making it beneficial for projects that require accurate spatial data.

Enhanced Mapping with RGB Cameras

With two 100 MP 4/3 CMOS RGB sensors, the Zenmuse L3 captures images with exceptional accuracy, achieving a Ground Sample Distance (GSD) of 3 cm at an altitude of 300 m. Its horizontal field of view extends to 107°, facilitating broader coverage in each image capture. Such features allow users to create high-quality orthophotos, Digital Terrain Models (DTMs), and more, all from one flight.

Advanced Data Collection and Processing

The high frequency of laser pulse emissions and the capability of returning multiple echoes contribute to the generation of highly accurate spatial reconstructions. Zenmuse L3 supports up to 2 million points per second and multiple returns, optimizing the balance between precision and scan versatility. This ensures that even in densely forested or urban environments, the system can gather substantial ground points for accurate surface modeling.

Efficiency and Daily Coverage

When mounted on the DJI Matrice 400, the Zenmuse L3 exemplifies high efficiency. A single flight at a standard altitude of 300 m can cover around 10 km², totaling up to 100 km² in a day. Additionally, this system simultaneously captures both LiDAR and RGB data, enabling extensive mapping outputs, including photogrammetric products with a lateral LiDAR overlap ratio of 20%.

Seamless Integration with DJI Ecosystem

The Zenmuse L3 is designed to integrate effortlessly with DJI's ecosystem. This includes the D-RTK 3 Multi-Station, DJI Pilot 2, DJI Terra, and DJI FlightHub 2 software, providing users with a streamlined, end-to-end mapping solution. The unified workflow allows for easier operation compared to traditional multi-platform setups, thus enhancing user experience and productivity.

Availability

The Zenmuse L3 is now available for purchase through DJI Enterprise dealers. This revolutionary system is set to transform various industries, including topographic surveys, emergency response, historical preservation, infrastructure inspection, and forestry, making advanced aerial LiDAR technology more accessible for professionals worldwide.

As DJI continues to expand the boundaries of drone technology, the Zenmuse L3 stands as a testament to its commitment to innovation and advancing professional applications across the globe.
