我认为这就是你想要的。

I think this what you want.

这叫做OCR： http：// en.wikipedia.org/wiki/Optical_character_recognition [ ^ ]。



很难找到好的开源OCR代码，但问题相对简单;这些地方的字体是统一的。另一方面，你不能使用字典来帮助识别。所以，你可以使用不那么好的东西。例如，甚至

http://en.wikipedia.org/wiki/Tesseract_% 28软件％29 [ ^ ]，

http://code.google.com/p/tesseract-ocr [ ^ ]。



正如您所引用的页面所示，该产品有.NET包装器。可以在Google代码上找到另外一个包装器： http://code.google.com/p/tesseract-ocr [ ^ ]。



另一种方法是使用MODI：

http://www.documentsnap.com/using -microsoft-office-document-imaging-to-ocr-for-free [ ^ ]，

OCRwithMicrosoft®Office [ ^ ]。



试试找到别的东西：

This is called "OCR": http://en.wikipedia.org/wiki/Optical_character_recognition[^].

It's really hard to find good open-source OCR code, but your problem is relatively simple; the fonts of the places are unified. From the other hand, you cannot use the dictionary to help recognition. So, you can use something not so good. For example, even
http://en.wikipedia.org/wiki/Tesseract_%28software%29[^],
http://code.google.com/p/tesseract-ocr[^].

As you can see from the page referenced about, there are .NET wrappers for this product. One more wrapper can be found on Google Code: http://code.google.com/p/tesseract-ocr[^].

One other approach is using MODI:
http://office.microsoft.com/en-us/help/about-microsoft-office-document-imaging-HP001077103.aspx[^],
http://www.documentsnap.com/using-microsoft-office-document-imaging-to-ocr-for-free[^],
OCR with Microsoft® Office[^].

Try to find something else:

http://bit.ly/1lr6oyp[^].

你可以使用EmguCV（.net的OpencCV包装器）



有在他们的wiki中获得车牌识别的样本



CSharp中的车牌识别

you can use EmguCV (OpencCV wrapper for .net)

there is a sample for license plate recognition in their wiki
