find curvature at depth map

I want to find curvature at depth map Look at the picture

enter image description here enter image description here

This is example of curvature Maybe if i represent image as function and take second derivative from it a can find curvatures. But i couldn't to implement it. (I tryed sobel operator from opencv)

Is there way out?

PS Sorry for my writing mistakes. English in not my native language.

That is not a depth map, it is a point cloud (but I assume it is generated from one single depth map z = f(x,y).

What curvature do you want to estimate? Mean, Gaussian, the whole 2nd fundamental form? See, e.g. here for definitions. Here's a recent reference on fast estimation methods:
