Take a look at the new calibration vi's in LV 6. They should be able to apply the corrections you need. I think they can correct for radial distortion and perspective. I am not sure yet what the limitations are.
If these functions are not sufficient, you might want to take a look at my image mapping toolkit (www.ammonsengineering.com). Once you figure out the mapping, it can create an undistorted image from the original image.
