Photogrammetry 2018-2019

Capturing 3D models from photographs of real objects

Software:                          Agisoft Photoscan, Meshlab, xNormal, Unity

Tasks:                                 Photography, mesh- & texture creation, python tool-scripting, arrangement and lighting in Unity

Coaches:                           Arie Kai-Browne, Jan Berger

Since 2018, photogrammetry has become one of my hobbies. All models and textures you can see in the gallery above have been made using the photogrammetry-process. The scene is an example I put together to understand how these meshes may be used in a game.

​

I have used this process to capture photorealistic models as well as tileable materials. Since I worked with Agisoft Photoscan so much but I always thought that the resulting scaling and pivots have been annoyingly off, I even scripted a little python-tool to automatically set the pivot and scaling of meshes within Agisoft Photoscan. The tool also gives the user a visualization of the pivot and 3D-Space that the object is placed in so little readjustments can easily be made by hand.
