I don't know how accurate is input and how accurate should be output but try
this:

1. Open image with lines in image manipulation software.
2. Assign each height to separate intensity of gray with rule: lowest height
is black, largest height is white.
3. Take filler/bucklet tool and fill each region (and line) of height range
with apropriate gray intensity (I hope lines are closed)
4. Look for largest distance beetween height-lines and perform blur/smooth
operation with this size/2 as radius.
5. Save image and use it as heigh field.

in step 3 if lines are not closed then add extra pixels to close it.

in step 4 you can experiment with lower radius of blur, handy blur with pencil
and/or separate blur for pairs of heights
