It's a "daily" partial panorama looking out over our city from a hill-
top vantage point, for use as a web page banner and archive into a
higher resolution "gallery". Humans seem to be intrigued by the
weather "at home" regardless of whether they are in town or on the
other side of the world. We have quite a lot of traffic to our web
cams although the view is fairly "ordinary" - just a landscape over
the city - and straight from the cam limited in FOV.
The web cam already exists, has been running for years, but we've
found it's low light performance is not brilliant (it's a great view
looking over the city from up here at night) and the mechanics of the
PTZ is not pixel-accurate. It's programmed to take new images at
varying locations and zoom levels every hour so it's constantly "on
the move".
So we're playing with the idea of using an array of "consumer" grade
usb cameras mounted in a weather-proof permanently fixed housing to
get better resolution, better low light performance, and more
reliable repeatability. In theory that should make scripting a
command line driven stitcher a breeze. Then run it off a cron job
(I'm personally in favour of a random time of day/night), use PHP /
GD or whatever to add a date and time stamp, possibly a caption and
just walk away and let it do it's "thing". Create it's own files, add
them to the gallery, update the masthead banner image etc.
