Following my recent success (thanks to those who helped)
de-tessalating a map, I've attempted to revisit
a previous example.
This one is comprised of (all)
the Boundary Commission Maps, 1885
from http://www.londonancestor.com/maps/maps.htm.
Each ward was shown on a single page of a book.
In order to get as much detail in as possible
they used different scales as appropriate,
and also rotated the maps, so that North
isn't always "up".
(I was having great difficulty using these maps
until I noticed that little fact... :-)
I have successfully detessalated these
maps into a large composite by
my usual dirty trick of declaring
them to have a very small field of view
(AKA long lens), and then optimising
in the usual "giga pan" style for
Y P R. Due to the changing scale
I also gave each map a separate
lens and optimised for HFOV too.
This all worked nicely.
However, I now feel that I should
do this panaorama "properly"
by using X,Y.
I gave it a try, but I couldn't
make it work.
Questions:
* Do I still need a separate lens for each map
do handle the scaling, or will Z motion deal
with that (is there a write up of X,Y,Z model?
the values seem quite odd).
* since some of the maps are rotated
do I need to optimise for R as I did
in my gigapan approach?
