You need to explain what you want more clearly, because right now I don't understand what you mean, so I can't help you. Please edit your question or answer in a comment.

How are you determining the angles of the red lines? It does not look like you are simply fitting a few of the pixels at the end of the curve to a line with polyfit(). So how are you setting those angles?
