Hi,
I'm always been a lurker here. biggrin.gif This is a great forum! Thanx to all! laugh.gif
I've written a small script in Python that extract the elevation map from an image with lights and shadows. It's a technic called "shape from shading" or photoclinometry. I've applied a simplified algorythm that works only with particular conditions. For example light must come exactly from left to right. It works well only with no patterned images and output images are affected by a boring striped pattern. sad.gif
Btw, I've worked on an Enceladus crater an this is the result.
3D rendering is by GRASS software.
In attachments there are the image of the crater, the 3D image and a map with profiles.
