ABSTRACT:
Hybrid measurement techniques for performing a digital 3D-model with respect to the building survey of an
ancient castle are shown. An analytical model of the castle, including sufficient information for digital image
rectification, is provide through multi image photogrammetry. Results of image rectifications are stored in a bitmap
library for further orientation in the 3D-model. Common software tools are used for this process. The software
packages RolleiMetric MR2 for the analytical multi image evaluation and Rolleimetric MSR for digital image
rectification support the photogrammetric part. Adobe Photosop is used for digital imaging. AutoCAD and
AccuRender are the tools for manipulating the analytical and digital 3D- model.
Am Beispiel der Bauaufnahme einer Burgruine wird der Einsatz hybrider Mefiverfahren zur Erstellung eines
digitalen 3D-Modells bis hin zur Animation gezeigt. Mittels Mehrbildphotogrammetrie wird ein geometrisches
Modell der Burg erstellt, das hinreichend Informationen zur digitalen Entzerrung der Fassadenaufnahmen
beinhaltet. Ergebnisse der Entzerrung werden in einer Bitmap-Library gespeichert und im analytischen 3D-Modell
orientiert. Hierbei werden die Móglichkeiten standardmáftiger Softwarewerkzeuge aufgezeigt. Neben den
photogrammetrischen Programmen RolleiMetric MR2 zur analytischen Mehrbildauswertung und RolleiMetric
MSR zur digitalen Einbildentzerrung werden Adobe Photoshop für die Bildbearbeitung, AutoCAD und
AccuRender zur Bearbeitung des analytischen und digitalen Modells eingesetzt.
INTRODUCTION
Surveys for performing the as-built structure of a
building are carried out for several purposes such as
preservation and restauration or studies on the
architectural history. A civil engineering project today
demands the presentation of the surveying results as
an analytical CAD-model which fulfils the
requirements of further data processing for various
tasks. Simulation and animation like walk throughs
are highly accepted presentation techniques today.
Finally the data base can be used for facility
management applications.
A complete building survey includes recording of the
facades as well as floor plans, section and height
measurements. A combination of photogrammetric
recording, electronic tacheometry and tape
measurements is the appropriate technique.
SITE SURVEYING AND RECORDING
Electronic Tacheometry. Usually a geodetic network
is necessary for recording the as-built structure of a
construction. Setting out and control measurements
