Render diffuse map into object uv space?

Unity Engine
1

Hello there~
I want to render diffuse map into object uv space in a shader.
I know lightmapping editer could do this, but it use cpu to calculate the map which is very slow.
I want to do it in realtime.
Any idea?
Thanks a lot~

The pic would show it clear.
