3D Portrait - Photogrammetry Tutorial (Blender + Meshroom) 《 攝影測量 - -3D人像》
Course Description Introduction:
It is difficult to obtain the array of portrait photography sampling photos close to 360 degrees without shadows, and it is also impossible to assemble the array camera by yourself, so this course provides 96 4K resolution sampling photos taken by the instructor himself to assist students to skip the threshold of photography sampling, directly through Meshroom for photogrammetry research, to find out the best various node operation solution parameters, and to reverse the understanding of The importance of sampling environment and full-image photographic array. This course will help participants to integrate and build up the conceptual techniques of photogrammetry with practical work.
This course is a photogrammetry-3D portrait initial solving course; A. Focus on helping students understand the difference between “photogrammetry” and “3D scanning”. B. Any 3D data can be optimized and mapped in Blender through the steps 1-6, and 7-8 is the final result presentation.
Course Description:
A.Meshroom:
1. Using MeshRoom to perform photogrammetric 3D portrait solving on 96 portrait photos taken by array cameras.
2. Through the solved data, analyze and explain the best sampling position of the array camera and how to shoot with a single camera.
3. Explain the importance of shadow-free lighting settings.
B.Blender:
1. Import the 3D portrait into Blender.
2. Edit the 3D portrait model in Edit Mode to delete and fill the number of faces.
3. Model retouching through Sculpting.
4. Reduce the number of optimized faces with Remesh.
5. Quickly disassemble the UV after.
6. Bake the Color map and Normal map of the low model by Cycles Engine with the high model.
7. Use Eevee Engine to render the 3D game quality like AAA grade.
8. Upload to Sketchfab website, adjust the parameters, and then release it to everyone.
