Loading a reference image from disk
The creation of shading reference is only necessary during commissioning or if the gain values
are changed considerably.
Note : The white reference target must be placed in the best focus plane of the camera.
Therefore any features on its surface (for example dust, scratches) end up in the calibration
profile of the camera. To avoid this if you use a static (non-moving) white reference target, use
a clean white ceramic or plastic material or paper. Ideally, the white object should move during
the calibration process because the movement results in an averaging process and the camera
diminishes the effects on any small variation in the white reference target.
