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.
