    Zenmuse L1

    The Zenmuse L1 integrates a Livox Lidar module, a high-accuracy IMU, and a camera with a 1-inch CMOS on a 3-axis stabilized gimbal. When used with Matrice 300 RTK and DJI Terra, the L1 forms a complete solution that gives you real-time 3D data throughout the day, efficiently capturing the details of complex structures and delivering highly accurate reconstructed models.

    Description

    Zenmuse-L1

    Instant Clarity. Superior Accuracy

    Generate true-color point cloud models in real-time, or acquire 2 km² of point cloud data in a single flight using the Livox frame Lidar module with a 70° FOV and a visible light camera with a 1-inch sensor. Render centimeter-accurate reconstructions thanks to the high-accuracy IMU, a vision sensor for positioning accuracy, and the incorporation of GNSS data. The Zenmuse L1’s IP44 rating allows it to be operated in rainy or foggy environments. The Lidar module’s active scanning method enables you to fly and capture point-cloud data at night.

    Integrating a Livox Lidar module, a high-accuracy IMU, and a camera with a 1-inch CMOS on a 3-axis stabilized gimbal, the L1 captures and generates point clouds in real-time at 240,000 pts/s and features a detection range of 450 m (80% reflectivity). As an end-to-end solution, DJI’s goal with the L1 is to generate precise 3D point cloud models with a focus on mapping.
