You can look for the surface handle in the axis children.

% Get current axe handle
hAxe = gca;
% Look for surface handle
vb = isa(hAxe.Children, 'matlab.graphics.chart.primitive.Surface')
hSurface = hAxe.Children(vb)
% Get values in surface properties
hSurface.XData
hSurface.YData
hSurface.ZData

EDIT : I assumed there is only one surface in this plot

Sorry I won't, since depends where you start at (type of image data, and you never explain us clearly what is it, your gave a color map, then a bananas, something about RGB, then a curve, then a fringe signal) and there might be many step more or less complex and requires some skill (for example compute the phase phi) to arrive at the heigh from the rawdata image of your fringes.

I gave you a general steps that must be carried out. If it's not clear, you should teach yourself or ask questions to your advisor, or whom ever gave you the task.
