Avtomatizacija relativne orientacije stereotipa : diplomska naloga

Vezočnik, Rok (author), Kosmatin Fras, Mojca (mentor), Gvozdanovič, Tomaž (comentor)

Diplomsko delo obravnava avtomatizacijo celotnega postopka relativne orientacije stereopara. V ta namen je bil v okviru praktičnega dela naloge v razvojnem okolju Visual C++ 6.0 izdelan testni program za avtomatizacijo tega fotogrametričnega procesa. Opisana so teoretična izhodišča, ki nudijo oporo pri razumevanju delovanja programa: relativna orientacija, digitalna obdelava slik za pridobitev vhodnih podatkov in robustna ocena pogreškov, ki je nujna, če hočemo nadzor nad pogreški relativne orientacije avtomatizirati in hkrati zmanjšati njihov vpliv na iskane orientacijske parametre. Predstavljene so tudi faze nastajanja testnega programa in shematični opisi njegovega delovanja. Poseben poudarek je bil posvečen različnim metodam zajema homolognih točk, ki so bile najprej določene ročno, nato polavtomatsko in nazadnje še povsem avtomatsko. Na ta način smo lahko ugotavljali prednosti in slabosti avtomatiziranega pristopa. Relativno orientacijo smo izvedli na različnih stereoparih, tako za aero- kot tudi za bližnjeslikovne posnetke.

Abstract

The present work describes an automatic approach to relative orientation procedure performed on an individual stereopair. For this purpose a test program has been built using Visual C++ 6.0 to enable this photogrammetric process to be fully automatic. The backgrounds are presented to describe the working of the program: relative orientation, image processing for determination of input data and robust estimation techniques, which are necessary for automatic control over the blunders, found in the relative orientation procedure and for minimizing their effect on orientation parameters. The work also describes the steps of building the test program and schematic diagrams of its functionality. A special emphasis is placed on different methods for determining conjugate points. Initially the points were identified and measured manually furthermore a semi-automatic approach was implemented and finally a fully automatic one. Determining the conjugate points according to these steps it was possible to compare the results and to point out the advantages and disadvantages of the automatic relative orientation. The program was tested on aerial and close range images.
