maybe
its
impossible...
even
if
the
camera
position
is
known,
you
could
only
get
a
projection
plane
from
the
coordianates
of
the
screen.
you
need
at
least
2
projections
from
the
camera
with
2
different
place
to
locate
the
object
in
world
coordinates.
Or
known
the
distance
from
the
camera
to
projection
plane.
I
am
not
really
sure,
thats
my
suggestion
from
my
knowledge.
Hope
it
is
helpful:)
