Need validation on my workflow

[bendead]

Hi,

I am just starting to use fixed aperture 25mm without microchip and I am unsure about my workflow.

- Doing camera calibration one time, taking picture of the chessboard, then load them and doing a calibrate lens, outputing a XML file
- Starting a new project, loading picture
- Loading the XML calibration file
- Changing the unknown pixel size and focal length, to 23.50 x 15.60  and 25
- Starting alignment with the following parameters :
   Accuracy : High
   Generic and Reference preselection
   Adaptative camera model fitting
- Once finished, running optimize camera alignment with
   Everything in general selected
   Adaptative camera model fitting

I just would like to know if it's the right way, or can I do it better?

Thanks

Benjamin
