Ask HN: Any (interactive) whiteboard scanning apps (i.e. draw onto canvas)

Interesting idea I'm toying with and I'm not sure how feasible this is yet, but curious to know if there is anything like this out there.

A whiteboard/drawing scanning tool that can then draw the captured image (to an appropriate degree of accuracy) onto a canvas that can then be interacted with. items moved, scaled, removed etc

Similair the 3m sticky note idea but not limited to square blocks of text. anything like that out there?
