Description

A purely experimental ticket.. It'd be nice if we had some ground truth datasets for use in regression testing (#12). Generating these synthetically might be a way to get data that we know exactly where it should be placed.

The things we need are:

  • imagery (images initially, then Eagle BIL format)
  • navigation (ASCII initially, then SBET)

The first thing is to see if this is at all feasible. The initial idea I had was to use a raytracer to generate images. We'd need to:

  • set up a raytracer (try povray)
  • create a scene
  • emulate the camera parameters for Eagle
  • animate it using ASCII XYZ PRH values to generate a series of frames
  • slice a single line out of each frame to make a BIL

Installed povray to arsf homedir - should work for you now.

Example scenes are in ~arsf/usr/share/povray-3.6/scenes/ Try examples like this:

cd /tmp
cp ~arsf/usr/share/povray-3.6/scenes/incdemo/logo.pov .
povray logo.pov
eog logo.png

Main povray site and docs are at http://www.povray.org/

Copy config files to your user:

cp /users/rsg/arsf/.povray/ ~ -a

Currently investigating a much simpler synth dataset.. Consider this ticket on hold for now.
