摘要：This article presents the results of studies related to the efficiency of applying additional parameters in aerotriangulation,using study blocks prepared in Poland in recent years. The results of the study of 20 blocks are included and are divided into four groups,differing in photo scale,number of photographs within a block and appearance of the measured projection center. The first group consisted of 8 blocks which were prepared for river maps from 1:26 000 scale photographs. The blocks had very irregular border shapes with many corners. The number of photographs in blocks was from 50 to 133. The second group consisted of 4 blocks which were prepared for digital terrain models and for orthophotomaps from 1: 26 000 scale photographs. The blocks had a rectangular shape. The number of photographs in the blocks was from 384 to 1 077. The third group consisted of 5 blocks which were prepared for digital terrain models and for orthophotomaps from 1: 13 000 scale photographs. The blocks had a rectangular shape. The number of photographs in the blocks was from 888 to 2 263. The fourth group consisted of 3 blocks which were prepared for road maps from large scale photographs. The number of photographs in the blocks was from 93 to 241. The shape of blocks was irregular. The blocks in the third and fourth group had projection centers measured by GPS. The number of check points in the blocks was from 20 to 54. The control points and check points were terrain features. The blocks were adjusted twice: both with and without additional parameters. Adjustments were prepared by BINGO software,which has functions consisting of 24 parameters. The efficiency of additional parameters was demonstrated as an increase of accuracy obtained for check points,in reference to the accuracy achieved in adjustment without additional parameters. The accuracy was increased for 15 blocks from 1 % to 70 %. For 5 blocks,it was reduced from 6 % to 16 %. The accuracy decrease appeared as a result of irregular block shape or an untypical net of control points.
