摘要: 如何在倾斜的航空影像上确定同名核线是数字摄影测量研究的重要问题。本文受“铅垂线轨迹法(VLL)”启发提出了“斜线轨迹法(SLL)”;在“斜线轨迹法”和核点坐标的特殊几何关系的基础上,提出了基于SLL确定同名核线和基于核点坐标确定同名核线的新方法,阐明了两种方法的原理、具体步骤,两种方法都提供了新的思路来确定同名核线,具有原理简单、几何关系明晰的特点。

Abstract: The theories of epipolar lines have particular significance for the development of digital photogrammetry , which make the task of searching conjugate points from stereo images an one-dimensional problem. As a result, methods to determine the conjugate epipolar lines is 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 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.

Key words: epipolar plane, epipolar point, corresponding epipolar line, VLL, SLL
