Bingo-F for block adjustment of Echallens has been used. I 
have adjusted original block and the block where original 
images were enhanced by addition a result of filtration of 
original image using highpass filtrer with Butterworth’s window 
and the block where original image was filtered with adaptive

Table 5. Results of aerial triangulation using best filtering and 
Bingo F in Echallens 
The results presented in table 5 certify an increase of the 
precision of aerotriangulation of blocks for images, which were 
adequately enhanced. Taking into consideration the prof. T. 
Schenk’s statement that “aerotriangulation’s success is the 
mostly dependant on precision of tie points transfer on 
following images”, my approach to the subject is reasonable as 
it causes an increase of the precision of fitting tie points on 
images. 
It can be concluded” that due to using the best method of 
enhancement the precision of automatic digital 
aerotriangulation increases by about 20%. 
Echallens block is test block on which were made many tests. 
Results of automatic digital aerotriangulation made by leading 
photogrametric centres in Europe is presented.

Precision of automatic digital aerotriangulation by using 
filtration of scanned aerial images has been increased. - 
Application such methods of image enhancement like: 
— adaptive filter, 
— image enhancement by addition to the original the 
result of filtration with highpass filter with 
Butterworth’s window in frequency space, 
- original image enhancement by addition the result of 
filtration of original image with Prewitt’s mask, of 
aerial images caused increase of precision of 
automatic digital aerotriangulation in each of the 
elaborated blocks.
