How to define initial camera params

[rlamarche]

Hi,

First thank you for this awesome project !

I wonder if it is possible to set initial camera params in the cameras.yaml file ? For example, if I define an OPENCV camera model, can I set initial fx, fy, cx,cy, k1, k2, p1 and p2 params ?

If they are guessed, how are they guessed ?

Do I need to manually update them in the database.db colmap file ? Because the column type is a blob and it might not be easy to do it on command line.

Thank you.
