Using version 1.1-linux. Occasionally some files can't be imported, while others work perfectly fine.

Python: Traceback (most recent call last):
  File "/home/colby/.config/blender/2.92/scripts/addons/blender_photogrammetry/__init__.py", line 76, in execute
    data = inputs[p.input].func(extract_props, scene=scene)
  File "/home/colby/.config/blender/2.92/scripts/addons/blender_photogrammetry/imagemodeler/extract.py", line 82, in extract
    f = (float(cinf['fbw']) / 2) / tan(radians(float(intrinsics['fovx']) / 2))
KeyError: 'fbw'

location: <unknown location>:-1

Attached is one of the problematic files. passat rzi.zip

Hi @Colbertson. The ImageModeler format is the least supported as I don't actually have a copy myself. I've been reverse engineering the format from a colleagues data. This is what their camera element contains:

<!-- theirs -->
<CINF i="1" n="Camera"        sw="608"  sh="392"  fbs="c" fbw="37.2245" fovs="v" fovx="56.0062" ds="c" rd="0.05" rstatus="v" hd="0" distoType="disto3i"/>
<!-- yours -->
<CINF i="1" n="Camera Device" sw="2048" sh="1536" fbs="c"               fovs="v" fovx="49.1343"                  rstatus="v" hd="0" distoType="disto3i"/>

Note the fbw attribute that I'm using as the sensor width combined with fovx to calculate the focal length. Your RZI file appears to be missing that attribute. If you can give some insight into the differences within ImageModeler between a file that works and this one I might be able to solve it. e.g. does IM show a different type of camera?
