根据匹配和新视点图像生成的需求，特征检测方法需要特征定位的精度较高，能同时检测出角点、边缘等不同特征等。

For the need of the matching and image synthesis the method of extraction can detect the different features of corners and edges and precision of the corner location is relatively good.

在众多图像特征中，角点不仅具有最少的数据量，而且稳定性极高，这使角点检测成为特征提取的重要分支。

Among the many image features, not only do the corners have the least amount of data, but also they are quite stable, which makes corner detection as an important branch of feature extraction.

作为一种数字图像测量方法，亚像素角点检测能够在数字图像中可以发现角点的亚像素精度的位置(简称亚像素角点检测方法)。

As a digital image measurement method, the sub-pixel accurate location of a corner can be found in digital image by sub-pixel accurate corner locator.
