Can any body be willing to tell me how to correct offset between the GPS/IMU and the camera center (which is also called lever arm offset) for DJI 600 since it is very important for photogrammetry?
Thanks!

Hello, can you explain "correct the offset" in a little more detail.

Hello ricci2,
D RTK gives us GPS reading and this location information refers to the D RTK position not the camera position and we have to translate that into camera center because the image geotag we finally get refers has to refer to the image center.  In DJI phantom there is not distance difference (at least not signficant) between the camera and the GPS and that is why we don't consider this offset (correct me if i'm wrong). But in M600 this difference is large and if has impact on the phogrammetric accuracy of image geolocation

I have attached a picture to show it grapphically

Thanks again!
