Bulk erase RGB Point data over structures to arrive at a bare earth model

I have 5 cm ortho imagery with the colour point cloud. I need to draw a polygon around the buildings in the imagery, to create the bare earth model as if the building did not exist. Is there a routine that will automate the erasure of the points.?

Thanks
