OpenCV Exposure Compensator类的含义 [英] The meaning of OpenCV Exposure Compensator class

问题描述

您好我想使用Exposure Compensator class standalone。
有没有人知道输入参数后面的含义？

Hi I want to use Exposure Compensator class standalone. Does anyone knows the meaning following input arguments?

compensator->feed(corners, images, masks);

例如，当我拼接两张图片时，我有两个角落：

For example when I was stitching two images I got two corners:

角落＃0：[ - 270,325]

Corner #0 : [-270, 325]

角落＃1：[ - 86,327]

Corner #1 : [-86, 327]

左上角的conrner怎么可能是负值？是什么意思？

How can the top-left conrner be a negative value? What's the meaning?

谢谢！

推荐答案

最后我做到了明确。它只是BIG地图中图像的左上角。由于此类特别针对图像拼接，因此在注册后，扭曲的图像可以有不同的位置。

Finally I make it clear. It's just the top-left corner of the image in the BIG map. Since this class is especially for images stitching, after registration, the warped images can have different positions.

只需使用两个准备好的（扭曲的）图像，给两个角[0,0]就好了。

Simply use for two ready (warped) images, giving the two corners [0, 0] is just fine.
