'How to color 3D mesh model using multiview image pixels

I have a question regarding the coloring of the triangle faces in a 3D model. I have a 3d mesh model and its corresponding multiview images. However my mesh is not colored, so I want to use the RGB information of the mv images to color the mesh triangle faces.

I am using the data from github below: https://github.com/zhuhao-nju/facescape/blob/master/toolkit/demo_mview_projection.ipynb

as you can see the image and mesh are aligned.

I also asked the author of the dataset about this issue. please find the response below:

Since I am a newbie in 3D data, I was not able to solve the problem.

Thank you for your help
