"Hi Michael, uSense is working hard on calibration since our experience is deep in spectroscopy.  The goal is to have a real calibrated NDVI value, to achieve that we have developed a calibration algorithm that it is in test stage. 
I think Mapir did…"

"I forget about the specs:
Reload time of camera: <2s.
Lens: f/2.8 Aperture, 82° HFOV, 23mm, Non-fish eye for low distortion.
We are also testing other lens configuration, what do you think about this lens set?
PD. I will post the spectral response…"

"Hi Juan, 
Thanks for the feedback.  Indeed, it is complicated to sync 4 cameras but it's possible with external trigger.  Pictures from the cameras could have a small delay (10-50ms) between them but It stills generate a good enough photos for post…"
