General Overview
Q: What is the DJI Zenmuse L2?
The Zenmuse L2 is a high-precision LiDAR and RGB mapping payload designed for the DJI Matrice 300 RTK and Matrice 350 RTK drones. It integrates a frame LiDAR system, a self-developed high-accuracy IMU, and a 4/3 CMOS RGB camera, providing precise, efficient, and reliable geospatial data acquisition.
Q: What improvements does the Zenmuse L2 have compared to the previous generation?
The Zenmuse L2 offers several enhancements over its predecessor:
The LiDAR's spot size has been reduced to approximately one-fifth of the L1's size at a 100 m distance, improving detection accuracy.
The RGB camera's pixel size has increased by 89%, from 2.4 × 2.4 μm to 3.3 × 3.3 μm, enhancing image quality.
Support for Laser Rangefinder (RNG) functionality for distance measurement.
