使用OCR获取扫描的文档文本时出现“ OCR运行时错误”

Question

我正在尝试从扫描的文档中获取文本。但是我遇到了错误“ OCR运行时错误”。我还对大型文档在web.config中进行了更改...如果您有任何解决方案，请帮助我...谢谢大家。

    <httpRuntime targetFramework="4.5.2" maxRequestLength="200000"
  executionTimeout="999999" requestLengthDiskThreshold="200000"/>

以下是我在代码段后面的代码：

   protected void Button1_Click(object sender, EventArgs e)
    {
        string filePath = Server.MapPath("~/Uploads/" + Path.GetFileName(FileUpload1.PostedFile.FileName));
        FileUpload1.SaveAs(filePath);
        string extractText = this.ExtractTextFromImage(filePath);
        string[] lines = extractText.Split(
        new[] { "\r\n", "\r", "\n" },
        StringSplitOptions.None
        );
       Label1.Text = extractText.Replace(Environment.NewLine, "<br />");

        var FirstName = lines[2].ToString();
        var FatherName = lines[3].ToString();
        var DOB =        lines[4].ToString();
        var PermenantAccountNumber = lines[6].ToString();


    string s = DOB;
        string t = "/";
        s = s.Remove(2, t.Length);
        s = s.Insert(2, t);
        var DateOfBirth = s;

        boObj.FirstName = FirstName;
        boObj.MiddleName = FatherName;
        boObj.DateOfBirth = DateOfBirth;
        boObj.AccountNumber = PermenantAccountNumber;
        blObj.SubmitBAL(boObj);
    }
 private string ExtractTextFromImage(string filePath)
    {
        Document modiDocument1 = new Document();
        modiDocument1.Create(filePath);

        modiDocument1.OCR(MiLANGUAGES.miLANG_ENGLISH);  //Getting Error here

        MODI.Image modiImage = (modiDocument1.Images[0] as MODI.Image);
        string extractedText = modiImage.Layout.Text;
        modiDocument1.Close();
        return extractedText;
    }
