since my results are only next to the so often promised results of the Reach module and my antenna is approximately 10 cm “behind the camera”, I’m thinking about doing lever arm correction.
I have written an simple Python script which corrects this offset under the condition that the UAV is flying in level and is pointing exactly in the direction from the previous and the following gps track point of the time mark.
The more I think about it, the more I come to the conclusion that I need to consider the IMU data of my UAV when I calculate the lever arm correction. Even if the camera would be exactly underneath the antenna, there would be an impact (some cm, may be 3-6 if the z offset is between 10 and 20 cm) when the UAV is not in level.
Has any one of you experience on the impact (in cm precision) of leaver arm correction and the workflow (with Photoscan)?
Thank you, Tobias
