What is the difference between boresight and sensor calibration?
In the boresight calibration process, the software computes the error component that is common to all exterior orientation estimates. This usually corresponds to the relative position/orientation of the camera to the GPS/IMU unit.
The sensor calibration consists in adjusting the camera parameters based on the camera type used. These values may include focal length, principal point, radial and decentering distortion parameters or LUT values.
