Ok, but then how to define the uv_vector corresponding to each triangle?

My image to be mapped consists of spots of a given dimension (eg. 1cm diameter),

also in cm. And I want to keep the scale of my image when I project it on the
scene's triangles.
Using uv_mapping without uv_vector doesn't produce what I expect but the
definition uv_vector is not clear for me.

Thanks in advance!
