16.6. cam2map4stereo.py¶
This program takes similar arguments as the ISIS cam2map
program,
but takes two input images. With no arguments, the program determines
the minimum overlap of the two images, and the worst common resolution,
and then map-projects the two images to this identical area and
resolution.
The detailed reasons for doing this, and a manual step-by-step
walkthrough of what cam2map4stereo.py
does is provided in the
discussion on aligning images in the Tutorial.
The cam2map4stereo.py
is also useful for selecting a subsection
and/or reduced resolution portion of the full image. You can inspect a
raw camera geometry image in qview after you have run spiceinit
on
it, select the latitude and longitude ranges, and then use
cam2map4stereo.py
’s --lat
, --lon
, and optionally
--resolution
options to pick out just the part you want.
Use the --dry-run
option the first few times to get an idea of what
cam2map4stereo.py
does for you.
Command-line options for cam2map4stereo.py:
- -h, --help
Display the help message.
- --manual
Read the manual.
- -m, --map <file.map>
The mapfile to use for
cam2map
.- -p, --pixres <PIXRES>
The pixel resolution mode to use for
cam2map
.- -r, --resolution <RESOLUTION>
Resolution of the final map for
cam2map
.- -i, --interp <INTERP>
Pixel interpolation scheme for
cam2map
.- -a, --lat <LAT>
Latitude range for
cam2map
, whereLAT
is of the form min:max. So to specify a latitude range between -5 and 10 degrees, it would look like--lat=-5:10
.- -o, --lon <LON>
Longitude range for
cam2map
, whereLON
is of the form min:max. So to specify a longitude range between 45 and 47 degrees, it would look like--lon=40:47
.- -n, --dry-run
Make calculations, and print the
cam2map
command that would be executed, but don’t actually run it.- --prefix <path>
Make all output files use this prefix. Default: no prefix.
- -s, --suffix <suffix (default: map)>
Suffix that gets inserted in the output file names.
