Objective

This project was undertaken to demonstrate how Structure-from-Motion (SfM) photogrammetry, particularly using drone technology, can be applied to capture and monitor architectural features. By leveraging aerial imaging, the goal was to create a highly accurate digital model of a building and its roof, serving both as a visualisation tool and a reference point for future conservation efforts.

Approach

A drone was used to capture high-resolution images of the building, including its intricate architectural details and roof structure. These images were then processed using Agisoft Metashape to create a textured 3D model. To enhance the model’s usability, it underwent post-processing, including cleaning and optimisation, ensuring it was clear and detailed for use on platforms like Sketchfab. This approach allowed for the seamless presentation of the building's structure in a user-friendly digital format.

Outcome

The finalised, cleaned model was uploaded to Sketchfab, where it can be easily accessed and explored. Beyond its immediate use as a visualisation tool, this model also functions as a valuable digital archive. It provides a baseline against which future models of the building can be compared, allowing conservationists and architects to monitor changes, identify areas of concern, and plan restoration efforts effectively.

Innovation

This project highlights the innovative use of SfM photogrammetry combined with drone technology to capture architectural features that are often challenging to document with traditional methods. The ability to create a detailed, textured 3D model of the entire building, including hard-to-reach areas like the roof, demonstrates how drones are revolutionising architectural documentation. Additionally, by integrating the model onto Sketchfab, the project bridged the gap between technical data and accessible digital engagement. Using this model as part of a time-series archive for monitoring structural changes exemplifies how photogrammetry can play a pivotal role in both preservation and proactive architectural management. This application of digital tools ensures that heritage and modern structures alike are safeguarded for future generations.
