[Elphel-support] Eyesis 4pi

[Jan Kohout]

Dear Sir/Madam, 
i have found your Eyesis4pi spherical camera system on the internet and it 
looks very interesting. 
However some things are rather unclear to me, so I would like to ask some 
questions. Because the questions are rather technical, I'm writing to tech 
support email address as well. 
1. How much does the quality of the image change with the speed of capture -
meaning how different is image captured at 2.5 fps from one captured at 5 
fps?
2. Since we already own a mobile mapping system and are not happy with the 
camera, are you able to deliver just the imaging part of your system? Only 
the set of cameras capturing the sphere.
3. On your web you say it takes 30 minutes to create a panorama. Is this 
value correct, and does it apply for every panorama, or just for the first 
and the subsequent panos take much shorter? When capturing tens of thousands
images per day, the 30 minutes seem just impossible.
4. The SSDs you use - is there a chance to install bigger disks and increase
operational time?
5. Have you tested the posiotional accuracy of your system in the 
challenging conditions of urban canyons/tunnels? If so, what were the 
results? We plan to get as many daily kms as possible (up to 400) and then 
use the data for survey purposes - this requires very good stitching of 
panoramas as well as precise position and attitude. From the MEMS IMU you 
use, I don't have much confidence in the final accuracy, but I might be 
wrong.

Looking forward to your reply. 
Best regards, 

Jan Kohout
