The viewing system parameters (in particular the mutual orientation of the coordinate frames fixed respectively to the left and right projection surface) probably have to be explicitly incorporated into solutions to the stereoscopic-matching problem in binocular vision. An algorithm for computing the relative orientation of the two directions of gaze from purely visual information without a prior solution to the correspondence problem is outlined. The availability of an algorithm of this sort seems to be a precondition for any stereoscopic-matching process that uses the epipolar constraint. It is further argued that fixation of objects in the near space requires integration of the results of stereoscopic matching over eye movements, and that this requirement puts rather tight restrictions on the possible form of representing the results of stereoscopic processing.
观察系统参数（特别是分别固定在左右投影面上的坐标系的相互取向）可能必须明确纳入双目视觉中立体匹配问题的解决方案。本文概述了一种算法，该算法可从纯视觉信息计算两个注视方向的相对取向，而无需事先解决对应问题。这种算法的可用性似乎是任何使用对极约束的立体匹配过程的先决条件。进一步论证的是，固定近空间中的物体需要在眼动过程中整合立体匹配的结果，并且这一要求对立体处理结果的可能表示形式施加了相当严格的限制。
