Right now we are using the Hugin open source panorama stitcher to do the automated stitching (off-board the robot). Our color correction is based on a white balance calibration of the cameras, though it was done indoors and so is pretty off. Hugin does color blending, which compensates somewhat.

It's automatically stitched together? How are you doing that?
Also, how are you correcting for color?
