DJI Zenmuse L1

The Zenmuse L1 is a sophisticated UAV load gimbal camera integrating a Livox Lidar module, high-accuracy IMU, and a camera with a 1-inch CMOS sensor on a 3-axis stabilised gimbal. When paired with Matrice 300/350 RTK and DJI Terra, it provides a comprehensive solution, offering real-time 3D data throughout the day. This setup excels in capturing intricate details of complex structures and generating highly accurate reconstructed models.

    Features

    DJI Zenmuse L1

    Create Digital Twins in All Environments

    A combination of powerful LiDAR and RGB data capture

    Unparralled Efficiency

    Create accurate, true-color 3D point cloud models instantly or collect point cloud data covering 2 square kilometers in one flight using the Livox frame Lidar module, featuring a wide 70° field of view, coupled with a visible light camera equipped with a high-quality 1-inch sensor.

    Exceptional Accuracy

    Achieve reconstructions with centimetre-level precision using the advanced high-accuracy IMU, a vision sensor that enhances positioning accuracy, and the integration of GNSS (Global Navigation Satellite System) data.

    Rugged Design

    The L1’s IP54 rating permits operation in wet or foggy conditions, while its active scanning Lidar module allows for night-time flights.

    Key Features

    • Simple Integration with the Matrice 300 drone makes it incredibly quick to deploy on site.

    • Fully Integrated Livox sensor and RGB camera, providing colour rendered point cloud data in real time.

    • Integrated RGB camera has a 20 megapixel 1-inch CMOS sensor which uses a mechanical and global shutter.


    • Auxiliary vision sensors helps to maintain altitude data in the event of GNSS failure in flight.


    • Instant Point Cloud Data provides the operator with real time information, supporting critical in-mission decisions.
