为什么Tessnet2不能提取文本？

Question

我正在使用 "tessnet2_64.dll"

这是我的代码，提取文本：

 try
            {
                var image = new Bitmap(@"D:\Tessnet2\C#\test2.jpg");
                var ocr = new Tesseract();
               // ocr.SetVariable("tessedit_char_whitelist", "0123456789"); // If digit only
                //@"C:\OCRTest\tessdata" contains the language package, without this the method crash and app breaks
                ocr.Init(@"D:\Tessnet2\C#\tessdata", "eng", true); 
                var result = ocr.DoOCR(image, Rectangle.Empty);
                foreach (Word word in result)
                    Console.WriteLine("{0} : {1}", word.Confidence, word.Text);

                Console.ReadLine();
            }
            catch (Exception exception)
            {

            }

结果输出：

146: I-18110
47: 88

如何提取文本"Hello"？谢谢大家

Answer 1

我已经通过更改解决了：

 ocr.Init(@"D:\Tessnet2\C#\tessdata", "eng", true);

到

ocr.Init(@"D:\Tessnet2\C#\tessdata", "eng", false);
