Beskrivelse
Zenmuse L1 er DJI´s første 3-akset gimbal styrte lidar for kartlegging
Systemet består av en Livox Mid-70 lidar, IMU med høy nøyaktighet og eit RGB kamera med 1″ CMOS sensor. Den har en rekkevidde opptil 450 meter og støtte for 3 retur signal. Her får man fargelagte punktskyer i sanntid utan behov for prosessering. Sammen med programvaren DJI Terra er dette en komplett løsning bestående av drone, sensor og programvare.
