Title : Combining Photogrammetry and Crowdsourcing for creating HBIM models (Constraints and Challenges)
Gehan Nagy, Samah Mohamed Elkhateeb,

Abstract :

The process of creating a prototype library based on historic architectural data and paving the way for virtually built heritage structures is known as heritage building information modelling (HBIM). The steps in HBIM are as follows: documentation phase, design phase, and three-dimensional (3D) model creation phase. Photogrammetry is used to generate 3D digital models of objects by uploading multiple photos using a certain software while crowdsourcing is the allocation of a task to a group of people, and the output sourced from the Internet. The aim of this study is to demonstrate constraints and challenges for creating HBIM models through combining photogrammetry and crowdsourcing. The proposed method is divided into two sections: first, in-depth literature review of photogrammetry and crowdsourcing in addition to exploring previous case studies to develop a framework for the process. Second, pilot experiments for testing the framework by generating HBIM 3D digital model for two old heritage buildings in Jeddah. It was concluded with certain considerations to avoid failure of creation of HBIM 3D model.
