From perspective drawing to low cost photogrammetry: Application in architectural studies

Abstract

Nowadays digital tools are booming. The evolution of the technologies used in archeology and in architecture is such that we are going more and more towards low cost and time saving. Indeed, today we can use free softwares in photogrammetry in order to make 3D surveys of architectural buildings. Fifteen years ago it only required the use of the 3D laser scanner, a very expensive technique. As part of the course reform of the second year at the national school of architecture and urban planning Tunisia in the course of descriptive geometry and perspective drawing, an experiment was conducted in order to introduce low cost photogrammetry using the free software 123 D catch by autodesk, 3DF Zephyr or Scann 3D on the mobile phone. The objective of this course is to make students experiment different techniques of representation such as photogrammetry, perspective drawing, using a mobile phone, a digital camera or a pen. The object of the representation is the Tunisian cultural heritage such as the archeological site of Carthage.
