The kernel is when en element is taken to the zero element in the image.

So, say you have a transformation that takes something from:

The kernel of this transformation would be:

where 0 is the zero element in L.

So in your case, the kernel would be any elements in the orthogonal projection that get mapped to the 0 element.

Hope this helps a little.
