matching point的用法和样例：
例句
- Thirdly, all pixels' gray values are acquired by the interpolation of the matching pairs.
最后对匹配点的灰度进行插值，得到插值像素点的灰度值。 - Thirdly, edge constraint was proposed to limit the search area in several pixels, and epipolar constraint was also used to achieve the matched points.
最后，提出边缘约束的方法匹配边缘上的点，将候选匹配点仅限制在几个像素，大大减少了搜索范围且提高了匹配正确率。
