USE OF PHOTOGRAMMETRY IN 3D MODELING AND VISUALIZATION OF BUILDINGS

Abstract

3D Models of architectural structures are very important in order to study, analyze and also to reconstruct and document these structures. Visualization of these models allows the user to get the photo realistic impression of the structures than graphic based object models. 3D visualization has many applications in the areas of architecture, civil engineering, tourism etc. Normally, field surveys are more accurate than photogrammetric measurements; nevertheless, they involve more personnel and consume a lot of time. Photogrammetry is a measurement technology that can be used for the extraction of 3D points from images. The present paper highlights the project using photogrammetry for accurate 3D modeling and visualization of structures.
