Hello Oleg, Thank you for fixing these issues!
Can you answer me please the following question: For a 4 sensor setup, how many 359 boards do I need? And, what would be necessary to combine 4 frames into one image? Can that be done? Because I'm currently working on a panorama camera like the one of Sebastian and Andrey, but I mine is a two sensor setup. Basically it's working but the quality is not satisfying. That's why it might be interesting to extend it to a 4 sensor version.
