1. 引用 tessnet2.dll (只有NET2.0版本)
2. 视图页
<%@ Page Language="C#" MasterPageFile="~/Views/Shared/Site.Master" Inherits="System.Web.Mvc.ViewPage" %> <asp:Content ID="Content1" ContentPlaceHolderID="TitleContent" runat="server"> 主页 </asp:Content> <asp:Content ID="Content2" ContentPlaceHolderID="MainContent" runat="server"> <h2><%: ViewData["Message"] %></h2> <p> 若要了解有关 ASP.NET MVC 的更多信息,请访问 <a href="http://asp.net/mvc" title="ASP.NET MVC 网站">http://asp.net/mvc</a>。 </p> <form id="form1" runat="server" enctype="multipart/form-data" action="indexnew" > <div> <a id="addAttach" href="#">添加上传文件</a> <div id="files"> <input type="file" name="f1"/> <%-- <input type="file" name="f2"/>--%> </div> <input type="submit" value="提交" /> </div> </form> </asp:Content>
3.后台代码
using System; using System.Collections.Generic; using System.Linq; using System.Web; using System.Web.Mvc; using tessnet2; using System.Drawing; using System.Drawing.Imaging; namespace MvcApplicationAndTesseert2.Controllers { [HandleError] public class HomeController : Controller { public ActionResult Index() { return View(); } public ActionResult IndexNew() { HttpPostedFileBase hf = HttpContext.Request.Files[0]; string path = Server.MapPath("~/image/"+DateTime.Now.ToString("yyyyMMddHHmmss")+".jpg"); hf.SaveAs(path); //D:\CSharp\TessnetTest\ReCaptcha.jpg是待识别图片在电脑中的路径 Bitmap map = new Bitmap(path);//@"D:\3.png" tessnet2.Tesseract ocr = new tessnet2.Tesseract();//声明一个OCR类 string txt = ""; List<tessnet2.Word> result = new List<tessnet2.Word>(); try {//当前识别变量设置:数字与大写字母,这种写法会导致无法识别小写字母,加上小写字母即可 ocr.SetVariable("tessedit_char_whitelist", "0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZ"); //应用当前语言包。注,Tessnet2是支持多国语的。语言包下载链接:http://code.google.com/p/tesseract-ocr/downloads/list //D:\CSharp\TessnetTesttessdata是语言包在电脑中的路径 ocr.Init(Server.MapPath("~/tessdata"), "eng", false); result = ocr.DoOCR(map, Rectangle.Empty); foreach (tessnet2.Word word in result) { txt += word.Text; } Console.WriteLine(txt); Console.ReadLine(); } catch (Exception ex) { } return Content(txt); } public ActionResult About() { return View(); } } }
