GIGASTART(1) User Contributed Perl Documentation GIGASTART(1)NAMEgigastart - assemble multi-row panoramas
SYNOPSISgigastart [options] image1 image2 [...]
Options:
-o | --output name Filename of created Makefile. Otherwise defaults
to 'Makefile'
-v | --fov Horizontal field of view in degrees. Otherwise
will be calculated from EXIF info.
-h | --help Outputs help documentation.
DESCRIPTIONgigastart takes a list of image files and creates a Makefile containing
rules to generate a single panorama from the images.
It utilises a multi-step strategy:
1. Consecutive pairs of photos are linked into one or more chains. 2.
Photos from the ends of each chain are linked if possible. 3. Photos
are placed in a rough grid with approximate positions. 4. overlapping
images with no links are linked if possible. 5. Positions are
optimised
This approach has some advantages:
The number of connections checked is directly proportional to the
number of images, so a 200 photo panorama should take twice as long as
a 100 photo panorama.
Different shooting strategies are supported: multi-row, zig-zag,
middle-top-bottom row-ordering, different number of photos in each row,
multiple angle-of-view.
Feature points are only identified once per photo and are reused.
The process is very suited to parallel processing, simply set the
maximum number of processes by redefining the $MAKE built-in variable,
e.g:
make MAKE='make -j 16'
Each step and photo pair is written as an intermediate .pto project, so
any problems can be fixed at this level, rerunning make will only
repeat work required to integrate those changes - The entire process
does not need to be rerun.
A disadvantage is that features are identified by generatekeys and
matched by autopano from the autopano-sift-C package. These features
are saved in a verbose XML file format which adds a significant IO
overhead, a future improvement could be to use a different caching
format for these files.
