Study on Photogrammetry Bridging Gap between Unstructured Data Images and Hologram Production

The entire process of modeling university buildings in 3D and visualizing holograms based on the data is covered in this study through photogrammetry technology using drones. After taking images of the school buildings from various angles using the DJI Mini 4 Pro drone, the high-resolution 3D model was constructed using Agisoft Metashape software. Afterward, the Unreal engine was used to extract multi-view images from various angles and output them in a three-dimensional form through the hologram printer. This study comprehensively covers all the steps from drone-based image collection, photogrammetry, 3D modeling, visualization, and hologram printing, and discusses in depth the impact of this technology on architecture and design. In particular, the innovative visualization technique combining drones and holograms has the potential to be utilized as an important tool not only in architectural visualization but also in education and training, design review, and industrial applications. Furthermore, this study suggests the expandability of this technology and explores directions in which it can be applied in various industrial fields.
