The graphical representations show that the interior accuracy of the 
investigated three line camera strip is only somewhat poorer than the 
accuracy obtained with error-free orientation parameters, 
It should be mentioned that in these computer simulations and in the 
simulations of chapter 3.2 a three Tine camera with parallel sensor 
arrays has been assumed. Ünder certain circumstances this configuration 
leads to a breakdown of the geometry of the system. This weakness is 
avoided, however, if the outer sensor arrays are rotated in the focal 
plane at certain angles, In /7/ this is shown in detail, 
3.2 Block adjustment of three line imagery 
The simulations of this chapter refer to a three line camera block 
consisting of three strips with sideward overlap of 602. In figure 6 
the groundplan of the block with the used object points (marked by 
circles) and the perspective centers of the selected orientation images 
(marked by crosses) is represented. In contrast to chapter 3.1, here 
different heights have been assumed for the object points. These heights 
were derived from a given digital terrain model (DTM). Figure 7 shows 
a perspective view of the DTM.
