Find the surface area of an object using stereo vision.

I want to find out the surface area of tree (only green part) using stereo vision. I know stereo vision and using the same I got the (X,Y,Z) values of tree, (of course one side only) (file is attached). I used delaunay function to calculate area but the problem is that I have some negative values of X and Y which cause error in surface area. How I can get the correct value of surface area using stereo vision?
It will be good if I can calculate volume also.

After using delaunayTriangulation, you have vertices and nodal connectivity in hand. Then you can use this function to get the area of each triangular element........sum the total areas, you will get the total sutgace area.
Have a look on function triarea from the package.
