透视链的构造

Construction of perspective chain

射影对应的形象定义是透视链 ,任何射影对应都可以用透视作为手段来实现 .但在已知射影对应而具体构造透视链时 ,往往会遇到作图构思上的困难。本文对点列与点列间同素透视链的构造以及线束与线束间同素透视链的构造作了深入的探讨 .

Projective correspondence is defined in images as perspective chain Any projective correspondence is established by means of perspective In this case,however,there exists some difficulty working out the practical construction The construction of the Point range homoprime perspective chain and that of the Line pencil heteroprime perspective chain are explored in the paper
