The Zenmuse L2 is a groundbreaking solution that seamlessly integrates frame LiDAR, a high-accuracy IMU system, and a 4/3 CMOS RGB mapping camera. Designed to enhance DJI flight platforms, the Zenmuse L2 delivers unparalleled precision, efficiency, and reliability for geospatial data acquisition. When paired with DJI Terra, it transforms into a turnkey solution for 3D data collection and high-accuracy post-processing.
Precision Redefined: Achieving extraordinary vertical accuracy of 4 cm and horizontal accuracy of 5 cm, the Zenmuse L2 sets a new standard for precision in geospatial data acquisition. This high-level accuracy is made possible by combining GNSS and a self-developed high-accuracy IMU system.
Efficiency Beyond Limits: Powerful and ready for action from the moment it’s powered on, the Zenmuse L2 covers an expansive 2.5 km2 area in a single flight, collecting both geospatial and RGB data with exceptional efficiency. Its intuitive operation, in conjunction with Matrice 350 RTK and DJI Terra, simplifies the workflow, reducing the operational threshold.
Frame-Based LiDAR Advancements: With a 30% detection range increase, the Zenmuse L2 offers detection ranges of 250 meters at 10% reflectivity and 100 klx, extending up to 450 meters at 50% reflectivity and 0 klx [3]. The smaller laser spots and denser point clouds, along with the support for 5 returns, enhance operational safety and efficiency, especially in densely vegetated areas.
Two Scanning Modes for Versatility: The Zenmuse L2 supports two scanning modes to cater to diverse task demands. In repetitive scanning mode, it ensures uniform and accurate point clouds, meeting high-precision mapping requirements. In non-repetitive scanning mode, it offers deeper penetration, making it suitable for power line inspection and forestry surveying tasks.
High-Accuracy IMU System: The self-developed IMU system, combined with the drone’s RTK positioning system, ensures improved accuracy in absolute position, speed, and attitude information. With real-time yaw accuracy of 0.2° and pitch/roll accuracy of 0.05°, the IMU system delivers exceptional performance with no warm-up time required.
RGB Mapping Camera Excellence: Featuring a 4/3 CMOS RGB mapping camera with a mechanical shutter, the Zenmuse L2 captures detailed images with enlarged pixel size and effective pixels reaching 20 MP. The camera’s quick photo interval, reduced operational costs, and the ability to take photos and videos even when point cloud collection is not needed make it a versatile asset.
