3d from bitmaps

I'm using VC++6.0
I haVE 2 IMAGES OF SAME OBJECT TAKEN FROM
DIFFERENT ANGLES.
I have the X & Y coordinates of the same point
from both images. For any point the Y coordinate
is same in both the images
but the X coordinate is changing.From this offset in X coordinate I have to
calculate depth (z coordinate) & display the 3d object on 2d raster screen

How can I do this ?
PLEASE HELP ME!
