摘要

我们利用倒易变换提出了通过 m 个点、与 n 条直线相切、满足 \(m+n=5\) 的圆锥在一般位置上的闭式解。我们还推导出了非退化实圆锥的代数和几何必要条件和充分条件。

Closed-Form Solution of Conic in Point-Line Enumerative Problem of Conic

We use the reciprocal transformation to propose the closed-form solutions to the conics through m points and tangent to n lines satisfying \(m+n=5\) in general position. We also derive the algebraic and geometric necessary and sufficient conditions for the non-degenerate real conics.
