我正在寻找一个执行 OCR 功能的 Windows 命令行工具。具体来说，我试图从这张图片中提取数字：

我尝试过 tesseract，发现它很糟糕。也许它需要我不知道的设置。我也尝试过其他一些，它们也很毒。一些在线的非常好，但我真的需要它作为命令行。
我非常感谢能够从上面链接的图像中准确提取数字的帖子。
非常感谢，
菲德尔
附注我可以做一些非常简单的图像处理，例如将其转换为空白和白色等。
I'm looking for a windows command line tool that does OCR. Specifically I'm trying to extract the number from this image:

I've tried tesseract and found it quite poor imho. Perhaps it needs settings that I'm not aware of. I've tried a few others and they too were pretty poxy. Some of the online ones were quite good but I really need it to be a command line.
I would really appreciate posts that accurately extract the number from the image in the link above.
many thanks,
Fidel
p.s. I could do some very simple image processing like converting it to blank and white etc.

由于多年来这里的一些链接已经腐烂了：我只是偶然发现了这个主题，发现 Tesseract 现在相当不错！
它是 FOSS，正在不断开发中，现已推出版本 4。

安装 链接到Windows 也是如此。然后
已经产生了一些有用的东西！
As some of the links here were rotten after the years: I just stumbled across this topic and found Tesseract to be quite good nowadays!
It's FOSS, in constant development and now on version 4.

installation links to binaries for Windows as well. And then
Yielded some useful things already! ????
