外极线约束将可能的候选点限制在直线分布，引入编码光用来确定光栅条纹的级次。

Epipolar constraint was applied to limit candidate-matching point to a line distribution and coding structured light was used to tell the grating index.

为了满足目标特征点的空间匹配一致性要求，提出了一种基于外极线约束条件新的视频图像判读处理模式。

In order to satisfy the consistency of the feature point spatial matching, a novel algorithm for video interpretation based on constraint of epipolar line is proposed.
