Figure 4. Focal plane arrangement of the CCD-sensors
This arrangement affords a stable and accurate compilation of the strip
model in any cases. This solution has been found by theoretical con-
siderations and was experimentally confirmed by computer simulation.
The compilation process for the reconstruction of the model now con-
sists of two main steps:
2.2 Correlation
By area correlation homologous image points in the three image strips
A.» B.» C. are determined. By interest operators suitable image points
are selected in the middle strip B, and their corresponding points are
determined in the outer strips A. and C. (Fig. 5). The results of this
correlation process are the line numbers N and the pixel numbers m
respectively their image coordinates x and y (see Fig. 3).
