4.6 Process in Agisoft Metashape

We used photogrammetry by utilizing the lightbox and DSLR camera to take pictures of Mulan’s toy from 360-degree directions. We applied baby powder to the toy during the shooting due to some reflections on the toy’s hair and clothes. It took us three attempts to obtain the final legitimate pictures, which we can put into AgiSoft MetaShape as our project's dataset. The pictures are divided into Chunk 1 (taken from above) and Chunk 2 ( taken from below), and the low-quality pictures are disabled. Then we followed the process of Aligning Photos, Building Point Cloud, Building Model/Mesh, Building Mask and Texture.

Yet, we did not use all masks because the result was not good. After refining the model to keep the 3D geometry parts we wanted, we finished building the texture and merged chunks, then exported the model as our final version. There are still some obvious flaws in Mulan’s D model, such as the holes on Mulan’s neck and jaw, the bumpy texture of her skin, her right ear is missing, and the unexpected mole under her neck for unknown reasons. Additionally, the baby powder helps with removing the reflection but also leaves foggy stains which ruined the original texture of this toy. Looking back at this process, we can see that the plastic material poses many challenges for 3D model creation.
