Take a Closer Look
Dual 100MP RGB Mapping Camera System
Equipped with dual 100MP 4/3 CMOS RGB sensors and a mechanical shutter, Zenmuse L3 delivers significantly enhanced accuracy and efficiency. Pixel binning supports an effective 25MP resolution.
High Accuracy
Vertical accuracy is better than 3 cm at 120 m altitude, better than 5 cm at 300 m, and better than 10 cm at 500 m [3], easily supporting mapping projects at 1:500, 1:1000, and 1:2000 scales.
High Penetration
Provides superior penetration capability with a smaller laser spot and higher single-pulse energy. For terrain mapping and similar uses, L3 captures more complete ground points for better results.
High Efficiency
When mounted on DJI Matrice 400, Zenmuse L3 delivers outstanding efficiency. At a flight altitude of 300 m, a single flight can cover up to 10 km², enabling up to 100 km² of daily coverage [2].
End-To-End Solution
Zenmuse L3 integrates with DJI's ecosystem to deliver an end-to-end mapping solution. Enjoy simpler, unified workflows from data acquisition and processing to application.
