Dr. Munjy, who I recently met at the TRB AFB80 summer meeting and his grad student Jacob Lopez have written an important paper on the rolling shutter effect inherent in all CMOS cameras. These are the cameras found on most UAVs. The rolling shutter effect becomes significant when flying the UAV fast and/or when flying at low altitudes.
The researchers studied the use of software to correct for the rolling shutter effect on a test site that had extensive ground control installed. They tested three different commercial software products, two of which claimed to remove the rolling shutter effect from the imagery. They used a number of control layouts varying from using 15 ground control points to just five.
