What improvements does Zenmuse L3 have compared to the previous generation?

Question

Accepted Answer

DJI Zenmuse L3 offers a range of improvements on the DJI Zenmuse L2. These include:

Hardware performance improvements:

Zenmuse L3 delivers enhanced LiDAR performance. When measured at the same distance, Zenmuse L3 produces a laser spot about one-fifth the size of L2 and supports up to 16 returns. This means much stronger penetration capability, greater range, and higher ranging accuracy.
The new dual 100MP RGB mapping camera system brings a horizontal FOV of up to 107°, compared to L2's 73.7°.
POS accuracy is improved to 0.02° for heading, and 0.01° for roll and pitch.

Accuracy and efficiency improvements:

Zenmuse L3's vertical accuracy is better than 3 cm at 120m altitude, better than 5 cm at 300 m, and better than 10 cm at 500 m. The point cloud thickness produced by Zenmuse L3 is only half that of Zenmuse L2, supporting advanced analysis and high-accuracy applications.
With a smaller laser spot and higher single-pulse energy, Zenmuse L3 offers superior penetration capability. In terrain mapping and similar applications, it captures more ground points with greater completeness, significantly improving the accuracy and integrity of terrain data for precise surface fitting and reconstruction.
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.
