I'm trying to find the distance between the red lines in the image, as pairs. I have the (x,y) co-ordinates of these red lines. What is the best way to measure the distance between each pair of red lines?

Minimum distance? Maximum distance? Average distance? Are they given just by endpoints or by intermediate points as well?

Or distance as a function of image column,
or distance as a function of position along the slanted centerline?

Provided that the lines do not cross, and using Roger's formula:
For each of the two endpoints in the first line, find the distance to the segment generated by the second pair of endpoints. Switch around and find the distance from each of the endpoints of the second segment to the segment generated by the first pair of endpoints. Take the minimum of these four distances.
