Using Stereo Webcam program
And Jasc Paint Shop Pro 8 program
Obtained many testers of creating stereoimages.

Unfortunately best to save images as bmp images
So as a treat(prepare your 3-D glasses)

NASA surely cant be wrong!!!
Well find out anyway

Being NASAs policy Everythings complicated!
On Sojourner, flat black sheet with 17 x 17
grid of white circles used, with perfect
separation and probably expensive equipment
Being a students policy Everything must be
simplified (dumbed down)
Bit of A4 lined paper with a ruler, a
pencil/permanent marker, and a Rich.
Extremely Cost Effective!!!

Initially the Sine rule is used to determine the
distance from one camera (say camera 2), to the
object.

Then basic trigonometry is used to ascertain the
perpendicular distance from the system.

Once these two distances are know, the distance
to any point, of known distance relative to the
camera, can be calculated.
Where (a) is known and angles B and A can be
found from the image obtained.

Screen
To find angles B, C and A, a screen of known size
is placed in front of the camera and moved closer
until it covers the whole field of view. The
distance from camera to screen is recorded.
