实现验证码图像文字的识别(C#调用DLL)

请先下载http://asprise.com/product/ocr/index.php?lang=csharp 的SDK.里面提供了详细的OCR方法,如下:
将发现图像框picbVeryfyCode里的文字和文本框.txtVeryfyCode.Text是一致的.
数字识别率我碰到的几乎是100% http://blog.csdn.net/crabo/ [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); //将返回string,并以"\r\n"结尾!! _veryfyCode = _veryfyCode.Substring(0,4); this.txtVeryfyCode.Text = _veryfyCode; } catch(Exception e) { this.lblResult.Text += e.Message; } }}
