When accuracy is mission-critical and time is limited, you need more than just a tool. You need a solution that elevates performance and simplifies complex operations. The DJI Zenmuse L3 is DJI’s next-generation aerial LiDAR system, built to meet the demands of professionals who require precision, reliability, and efficiency in every flight.
As DJI’s first long-range, high-accuracy LiDAR payload, the L3 combines advanced sensing, high-resolution imaging, and precision positioning in a compact, integrated design. Engineered for the Matrice 400 and optimized for DJI’s full ecosystem, the Zenmuse L3 delivers exceptional results in geospatial surveying, infrastructure inspection, and public safety applications—capturing more data, with greater clarity, in less time.
At the heart of the Zenmuse L3 is a powerful 1535nm laser, operating in the near-infrared spectrum. This wavelength enables longer-distance scanning, up to 950 meters, even on low-reflectivity surfaces while maintaining a Class 1 safety rating.
It’s the ideal balance of safety and power, allowing for high-altitude operations that boost coverage and efficiency without sacrificing precision. When mounted on the DJI Matrice 400, the L3 can cover up to 100 km² per day at a typical flight altitude of 300 meters, making it one of the most efficient payloads in its class.
The L3 also supports up to 16 returns per laser pulse, a major leap beyond conventional systems. Each return represents a surface the laser pulse hits—like treetops, branches, and the ground.
Capturing multiple returns allows the L3 to build layered point clouds that reveal both surface and sub-surface details. This is essential for mapping terrain under dense vegetation, inspecting infrastructure surrounded by foliage, or modeling complex environments with vertical depth.
In addition to its advanced LiDAR, the Zenmuse L3 integrates a dual-camera system with two 100MP RGB sensors. These large-format M4/3 sensors deliver crisp, true-color imagery with sharp detail and enhanced fidelity, providing visual context to your LiDAR data. This is especially useful for generating high-resolution orthophotos, colorized point clouds, and accurate 3D models—all in a single flight.
The imaging system also features a mechanical shutter with a rapid 0.5-second interval, enabling clean captures even at higher flight speeds. This allows for fast, blur-free data acquisition across large areas, improving overall efficiency without sacrificing image quality.
Whether you’re mapping urban structures or monitoring construction progress, the L3 ensures both geometry and color are captured with precision.
The Zenmuse L3 is engineered for professional-grade accuracy, supporting mapping scales as fine as 1:500. At 150 meters altitude, it delivers vertical accuracy within ±3.5 cm and horizontal accuracy within ±5 cm.
This level of precision ensures reliable elevation models, tight surface reconstructions, and compliance with industry standards for surveying and engineering projects.
Beyond large-scale accuracy, the L3 excels in micro-level detection. With a laser beam divergence of just 0.25 mrad, the spot size is approximately one-fifth the size of its predecessor at the same range.
This enables the system to detect narrow features such as power lines, edges, and small branches with exceptional clarity, even when operating at high altitudes.
The Zenmuse L3 captures LiDAR and RGB data simultaneously, allowing teams to generate multiple high-value mapping outputs from just one flight. This includes point clouds for structural analysis, digital orthophoto maps (DOM) for true-color overviews, digital elevation models (DEM) for terrain insights, and textured meshes for 3D visualization.
This all-in-one data collection dramatically reduces time in the field and simplifies post-processing. Instead of flying multiple missions or switching payloads, operators can gather everything they need in one efficient pass—saving time, lowering costs, and ensuring data consistency across all outputs.
The Zenmuse L3 features an adjustable laser pulse rate, from 100 kHz to 2 MHz—giving operators full control over point density and penetration depth depending on mission needs. Whether you’re capturing dense vegetation, scanning open terrain, or extracting fine structural details, the L3 adapts to deliver the optimal balance of speed, coverage, and accuracy.
To further enhance data capture, the L3 offers three intelligent scanning modes, each designed for specific mapping objectives:
These versatile scan options give surveyors and inspectors greater control over how data is collected, ensuring consistently accurate results across varied environments.
The Zenmuse L3 is more than just a sensor, it’s a key part of DJI’s complete geospatial solution. It integrates effortlessly with the DJI ecosystem, including DJI Pilot 2 for flight operations, DJI Terra for post-processing and PPK calculations, and DJI Modify for advanced modeling and classification. It also connects with DJI FlightHub 2 for real-time mission planning and cloud-based data management.
From planning to final deliverables, the L3 streamlines every step of your workflow. With seamless hardware and software compatibility, your team can move faster, stay organized, and consistently deliver high-quality results.
