Corretion of arial-photographs with mapcalc?

Dear GRASS-Users,

  I had a question from one of my students about the possibility
  of corrections of arial-photographs.

  1) Is it possible to manage this with mapcalc?
     Is there someone, who did this before and who has
     a mapcalc script?

  2) Is there another software, which can manage this job?

Thanks in andvance

  Andreas
