DESCRIPTION OF THE APPARATUS
System of projection. Collimation optics. Measurement of
vertical parallaxes. Distortion correction.
As seen in the outlining figure (1) the axes of the two projection
cameras result as being horizontal in the fundamental position, so
that <p = o) = 0
As with all previously created Santoni plotters, so with model V,
the straight projecting pairs are obtained by mechanical means:
with guide-rods (a-b) held by universal joints (1-2) materializing the
centers of view of the perspectives ph T , ph n .
Said rods, in the object space, are connected to the third carriage
of the coordinatograph (the three carriages of the latter move in
the direction of coordinates X, Y, Z).
On the side opposed to the coordinatograph, in correspondence
to the taking camera, each rod supports one tubular part that sli
des freely along the rod itself.
