It is not a complete 360 degree but displayed as a 360x180 degree
panoramic picture format. There is no tripod used. I only used my hand
to take all these pictures. It shows that Panorama Tools can handle
these pictures as well.
Additional techniques that I find useful is to use the lens data from
previous pictures to quickly speed up the optimisation process.
I no longer need to do the lens view and distortion optimisation any
I also notice that this is a very effective way of measuring lens
It also shows that it is no longer important to have an extremely low
distortion lens because they can be corrected digitally.
