Add Fixed Sensor Size and Focal Length

[brothermechanic]

Hello
Thank you for this addon, it much better than others calibratios ever!
Can you add fixed camera data for set sensor size and lens focal leight manually?
This is good for known photos metadata info for better calibrations
Thank you!

Thanks!

I don't recommend relying on the metadata. It will not be precise enough. If you use a prime lens, then the focal length is not actually what is written on the lens and if you focus near and far, then the focal length may even change. If you use a zoom lens, then the metadata will only contain the approximate focal length anyway.

Oh, I think you may be right, thank you)

I will keep this open. You are not the first to ask for this and some people may actually really need this. For example, animations often need the same focal length for each frame.
