Hi tdomney,
I found this info about the Waldoair Xcam online:
The XCAM-B is an airborne camera system using commercial off-the-shelf components. Manufactured in the United States, the system includes dual 18.0MP DSLR cameras and an optional thermal camera, with an impressive cross-range of 10,200 pixels,
Looks like they have two standard DSLR cameras inside their pod in combination with some other sensors such as a GPS and IMU (for geotagging, I guess). They are probably using two Canon Rebel T6 DSLRs (or similar). Therefore, I don't see any reason why you shouldn't be able to process such imagery in PhotoScan.
Regards,
SAV
