Structure from Motion is another digital method we made use of that through computational imaging can produce 3D models. The photos we took during the first stages are, thereby, crucial for the computational processing in Agisoft Metashape as all necessary information to reconstruct a 3D model is obtained. Photogrammetry and computer vision methods for analysing are in this process combined, ensuring a precise reconstruction of the given object, in our case of the Funko Pop! vinyl figure Vincent van Gogh. To form a 3D model, the methods create the exact camera positions and the geometry of the object (Papadopoulos, n.d.).
Interesting to notice, is that sometimes it can be beneficial for this method to take more pictures than expected. However, it is important to take neither too little nor too many pictures of the objects. For instance, during the process we did take more picture than necessary which resulted in the software not processing the images properly and failing to comprehend to structure of the figure. The issue here was not only the large amount of pictures but also, the fact that we did not take pictures from enough different angles.
Structure from Motion is particularly useful as it can be used in many different areas to easily detect a given 3D object (Papadopoulos, n.d.). Within the software, we needed to go through every picture to find any duplicate and to disable those with a lower quality level. The pictures we selected in the end were the ones used in the reconstruction process (Papadopoulos, n.d.). After that, we were able to start the process in Agisoft Metashape to reconstruct the 3D model of the Vincent van Gogh Funko Pop!.
