New Methods of Determination of Conjugate Epipolor Lines in Aerial Images
确定航片同名核线的新方法

The theories of epipolar lines have particular significance for the development of digital photogrammetry,which makes the task of searching conjugate points from stereo images an one-dimensional problem.As a result,methods to determine the conjugate epipolar lines have been discussed in many papers.SLL(sloping line locus) is presented in this paper as an extension of VLL(vertical line locus) method.Then,based on SLL and geometric characteristics of the epipolar point,this paper proposes two new methods to determine conjugate epipolar lines.The new methods are simple in theory and have explicit geometric relationship,which makes them easily applicable.
