and the scanner 
In this section the analog camera, Zenit E, was used together 
with the HP scanner to produce the digital images. First the 
camera was used to collect a nımber of image pairs with 
different B/H ratio, and these images are scanned with 
different resolutions. Sixteen well-distributed control points 
were chosen to solve the resection problem for each image. 
The intersection process is used to evaluate the experiments. 
Table 1 shows the different combinations of the B/H ratios 
and the used resolutions. Figure 3-a, b, and c show the RMS 
errors for the different experiments.

Table 1. First System Configuration Camera 
The digital camera was used to produce the digital images 
directly. The images were taken with B/H ratios shown in 
Table 3. The resection and intersection processes were 
applied to solve for the camera parameters and the ground 
coordinates of the target points. Figure 4-a, b, and c show the 
RMS errors for the different experiments using the digital 
  
    
  
camera.
