Show the Potential of Agisoft Photoscan Software to Create a 3D Model for Salhiyah Residential Complex in Baghdad Based on Aerial Photos

Abstract

This research includes the use of aerial photos that taken by metric camera for the constructing 3D digital models, because of these models have developed significantly and increase demands to meet the requirements of several applications. The credibility of these models is essentially depending on the methods of data processing, tools that adopted for solution and quality of data. Whereas in this research automatic method was utilized for data processing, the 3D coordinates identification and extraction of the 3D model. Several software's can be utilized for data processing and the 3D coordinates identification such as Agisoft Photoscan software. To examine the accuracy and the reliability of the results of this software for precise 3D modeling applications, the results were evaluated based on statistical methods. To achieve this aim, The study was done in Baghdad / Salhiyah Residential Complex using data collected by an airborne metric camera with 911.82 m height of flying. To evaluating the final accuracy of a 3D digital model, an evaluation process were done based on the height of some different buildings distributed in the study area was implemented. Whereas the final accuracy of the 3D model based on the root mean square error (RMSE) was equal to (0.277m).
