为什么Tesseract OCR在使用C＃3.5的Asp.net中不起作用？ [英] Why Tesseract OCR is not working in Asp.net with C#3.5?

问题描述

为什么Tesseract OCR在使用C＃3.5的Asp.net中无效？我能够在c＃应用程序中从扫描图像中提取文本。但是在Web应用程序中使用同样不起作用。这里的OCR.Init方法在Asp.net中不起作用，但在windows应用程序中没有这样的问题。我在bin目录下设置了tessdata文件夹，并且还添加了tesseract bll作为参考。

我的代码如下：

Why Tesseract OCR is not working in Asp.net with C#3.5? I am able to extract the text from the scanned image in c# application. But while using in web application the same is not working. Here OCR.Init method its not working in Asp.net but in windows application there are no such issues.I have set the tessdata folder under bin directory and tesseract bll also has been added as reference.
My code is as follows:

string Results = string.Empty;

 string path = @"D:\OCR\test.jpg";
 // string path = Server.MapPath("~/Images/test.jpg");
 Bitmap image = new Bitmap(path);
 tessnet2.Tesseract ocr = new tessnet2.Tesseract();
 ocr.Init(null, "eng", false); // To use correct tessdata
 
 //To recognise the text in the selected image area (x cordinate,y cordinate,width,height)
 if (rdSelectedAreaTextImage.Checked == true)
 {
     int xCoordinate = int.Parse(txtXCooridnate.Text);
     int yCoordinate = int.Parse(txtYCooridnate.Text);

     List<tessnet2.Word> r1 = ocr.DoOCR(image, new Rectangle(xCoordinate, yCoordinate, 1187, 623));
     foreach (tessnet2.Word word in r1)
     //if (word.Text.Contains("About"))
     {
         // Console.WriteLine("{0} : {1}", word.Confidence, word.Text);
         Results += word.Text;
     }
 }
