C#調用DLL實現映像文字識別(OCR)

請先下載http://asprise.com/product/ocr/index.php?lang=csharp 的SDK.裡面提供了詳細的OCR方法,如下:

將發現映像框picbVeryfyCode裡的文字和文字框.txtVeryfyCode.Text是一致的.

數字識別率我碰到的幾乎是100%

[DllImport("AspriseOCR.dll")]
  static extern string craboOCR(string file, int type);

private void GetVeryfyCode()
  {
if(File.Exists(_imgPath))//ok now?
   {
    try
    {
    this.picbVeryfyCode.Image=System.Drawing.Bitmap.FromFile(_imgPath);
     _veryfyCode=craboOCR(_imgPath,-1);   //將返回string,並以"\r\n"結尾!!
     _veryfyCode=_veryfyCode.Substring(0,4);
     this.txtVeryfyCode.Text=_veryfyCode;
    }
    catch(Exception e)
    {
     this.lblResult.Text+=e.Message;
    }
   }
}
