It's not clear what you mean by the 1 meter. Is that the error? It would be
more helpful if you define segment and point. How are they being defined? Do
they involve floating point numbers? The general answer to your question is
that sympy can test whether a point is in a segment, but because of floating
point issues it likely won't be able to do so reliably with floating point
numbers.
>>> Segment((0,0), (2,2))
Segment(Point(0, 0), Point(2, 2))
>>> s=_; Point(1,1) in s
True
