Table 4. Results of aerial triangulation in project Echallens
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

UA
filter. As the result the best images after their enhancement in
object and frequency space were elaborated.
The results of AT are presented below.

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.
