Figure 5. The original image (upper) and DSM (lower) (corresponds to the lower part of Figure 3). 
In order to check the accuracy of the generated DSM, we 
randomly selected twenty five correspondences. We 
manually measured the image coordinates of the 
correspondences and then compared it with the image 
coordinates of the correspondences which are automated 
generated by the program. We applied space intersection to 
these correspondences to determine their coordinates and 
check their difference in the object space. Table 2
