How to render a mesh as an image with the same perspective as the reference image.

[qwerwsc1]

First of all, thank you very much for your work.

I encountered a problem while reading the paper and organizing the results. As shown in the image, we get a 2D image of the render and a 3D model of the mesh, but in your paper, you can align them.

I would like to know how this is achieved, and how to render the output mesh.ply as an image with the same perspective as the reference image.

Thank you very much for your reply.
