I'll try to reformulate:

You have a vector layer of points.
You have a raster layer (might be a DTM).

Foreach point feature of the vector layer:
     - take the location of the point
     - calculate an interpolated value of a chosen band at the point 
location
     - save this value in a field of the feature
