A Lidar + RGB Solution for Aerial Surveying - With Protection!

Elevate Your Aerial Surveying with DJI Zenmuse L1 LiDAR Payload

Experience the future of aerial surveying with the DJI Zenmuse L1 LiDAR payload, now available at Keystone Precision Solutions. This cutting-edge solution 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.
