推荐答案
在回答您对aranga的评论时，
In answer to your comment to aranga,
这取决于您的图像，或更确切地说，取决于它具有多少个通道.普通图像将具有3个通道(RGB，尽管实际上是反向的，所以是BGR)，您的图像似乎是灰度的，或者无论如何在第一个通道中只有值.
this depends on your image, or more precisely on how many channels it has. A normal image will have 3 channels (RGB, though it is actually in reverse, so BGR), yours seems to be grayscale, or in anycase have only values in the first channel.
我刚刚检查了一下，的确可以，
And I've just checked, indeed if you perform
cvtColor(src,dst,CV_RGB2GRAY);
要将三通道RGB图像转换为灰度图像，灰度图像只有1个通道.但是也许您会知道为什么您的图像仅使用1个通道...
to convert a three-channel RGB image into grayscale, the grayscale image has only 1 channel. But perhaps you would know why your image is only using 1 channel...
