DJI Zenmuse L3 Lidar

Order the latest mapping lidar - DJI Zenmuse L3!

This is an advanced solution for high-precision 3D scanning. The Zenmuse L3 module is designed to integrate with DJI Matrice drones. It combines lidar, camera and inertial navigation. You will receive detailed digital twins of the terrain.

• Highly accurate 3D mapping with color scanning.

• Density up to 240,000 dots per second for detail.

• Simultaneous recording of lidar data and RGB video.

• Ready-made workflows for mapping and inspections.

• Seamless integration with the DJI Matrice 300/350 platform.

3D scanning technology

The Zenmuse L3 lidar uses a pulsed laser rangefinder. It measures the distance to objects around the drone. The system creates a point cloud at high speed. At the same time, the built-in camera takes RGB pictures. Camera data is overlaid on a point cloud.

This allows you to create colorful 3D models. The terrain models are incredibly detailed. You can measure any objects at a distance. The accuracy of the model reaches the centimeter level. This exceeds the capabilities of conventional photogrammetry.

Integration and professional application

The Zenmuse L3 module is designed for the Matrice 300 and 350 drones and can be easily installed on a compatible gimbal. Control is carried out via the DJI remote control and the application. DJI Terra software processes the data. You will receive ready-to-use 3D models.

The lidar range is several hundred meters. It scans even complex objects efficiently. For example, power lines or building facades. The system operates in various weather conditions. It is less dependent on lighting than cameras.

This tool is necessary for topographic surveying. It is used in the mining industry. Lidar is ideal for forest inventory and construction monitoring. It helps conduct infrastructure surveys.
