Hi everyone,
Does anyone have guidance on how to perform boresight calibration for a gimbal-mounted camera?
I am trying to accurately determine the Point of Interest (POI) corresponding to the center of the camera’s field of view. I am currently using the CAMERA_FOV_STATUS message, and from my understanding, the POI is calculated based on the gimbal pitch/yaw angles and intersected with terrain data (when available).
However, I am observing a consistent shift in the calculated POI. In some cases, the camera is clearly looking ahead at a distant building, but the POI marker (lat/lon from CAMERA_FOV_STATUS) appears behind the building on the map.
I would like to understand:
How the camera optical center is modeled internally
Whether boresight (camera–gimbal alignment) errors are accounted for
If there are any known angle offsets or calibration parameters that should be applied
My flight conditions are:
Altitude: ~250 meters AGL
Target distance: ~1.5–2 km
Is there a recommended procedure or parameter set to accurately align the camera optical axis with the reported POI, especially for long-range targets?
