seen as a “System calibration” including the frame grabber and not as a camera only calibration since the change of the 
frame grabber could result in a change of the interior orientation parameters.

2.3 Tests using high resolution cameras 
In an effort to improve the image resolution of our system and its mapping capabilities, it was decided to replace the old 
standard video cameras (RS-170) with digital high-resolution cameras. For economical reasons, it was decided to 
purchase only two high-resolution cameras. The selected model was the Hitachi KP-F100, 1300 by 1024 pixels. It has 
analog and digital outputs (10 bits). The goal of our project was to demonstrate the feasibility the concept....if it works 
with two cameras, it will also work with 4 cameras. 
A new mount was built in order to accommodate the 2 cameras for calibration and experimentation in the laboratory but 
also with the idea for it to fit directly into a Leica (Wild) aerial camera mount.
