Possible to get a texture (as jpeg) of a reconstructed 3D model?

[przemekblasiak]

Right now, I reconstruct 3D scenes based on RGBD information and save the resulting mesh as a .gltf model. It's colored (triangles have colors) but I'd like to have that color information as a separate texture file (e.g. jpeg).

I'd appreciate any clues on how to approach it and if it's possible to accomplish with Open3D or other tools.

• There are libraries like openMVS that solve the problem of mesh texturing.
• There are papers like Texture Mapping for 3D Reconstruction with RGB-D Sensor on the subject.

All in all, I believe it makes sense for Open3D to offer even a simple texture projection algorithm based on RGBD (+odometry) to make the reconstruction pipeline complete.

Yes, that's really the last piece missing

Have you checked open3d.t.geometry.TriangleMesh? It has functions for computing uv coordinates and baking vertex and triangle attributes to textures

You are right, but it doesn't support projecting textures from multiple camera views onto the mesh
