How can I take an image and orthorectify it automatically with open source software? The information associated with each image is:

  • camera specs
  • latitude, longitude, elevation of the camera
  • orientation of the camera: facing down off a UAV, roll pitch and yaw are given

I want to output a geotiff file and hopefully end up stitching the images together to create a map.

Maybe the GRASS module i.ortho.photo can help? –  Micha Jul 13 '12 at 9:29

this link describes the use of the open source software Palentier , but i don't know the accuracy supported with this suite, and if it could produce DEM or just stitched photos.

i think the point cloud library could help too.
