VIDEOGRAMMETRY AND CAAD FOR ARCHITECTURAL RESTITUTION OF THE OTTO-WAGNER-PAVILLON IN VIENNA

Although there is an unchanged demand for the recording and documentation of the cultural heritage, modern acquisition and analysis techniques are rarely used. The paper shows results of the application of videogrammetry and CAAD for the architectural restitution, contributing thus to the CIPA test “Wagner-Pavillon”. The images were acquired with a S-VHS camcorder, which today are considered to be “house-hold items”. The results are compared to the results obtained by other institutes, which have used conventional photogrammetric techniques. The accuracies of about 1 cm on the object which have been obtained are compatible to those derived by classical photogrammetry, while the unique characteristics of digital photogrammetry (automation, computer compatibility, relaxation of expertise) give videogrammetry distinct advantages.
