【小记】:大胆尝试才能突破,某个中医药大学有一批图片需要处理(ORC),然后进行数据挖掘。之前没有接触过ORC这个东西,但是还是应允了。在网上搜索一番,关于中文图片识别,最终敲定为基于微软的OneNote,其识别率相对较高。网上这个技术点的资料真心不多,后来于博客园找到一篇博文,但是那个程序还是bug百出,而且只是单处理。后来经过一番摸索逐个突破,批处理完成。然后进行界面设计,这些零碎工作完成后,便是入库处理。由于OneNote生成的xml文件封装好的,即不可视的。便将其代码处理生成txt文件,再进行Oracle入库处理。入库前需要文件内容审核,并且在WPF开发中数据绑定和分页中做了独特处理。现在经过半个月的工作,本项目做个阶段总结。一则知识总结便于二次开发,尽量保持程序流畅性,核心知识做以梳理;另外,相关WPF和OneNote常用技术共享,便于部分园友所需。本人技术有限,欢迎交流。项目还未结束,暂作阶段文章发布,随后相继发布。
【1】开篇概述:在对本章技术介绍前,还是梳理下思路。描述下本章功能和开发过程。做个系统大致了解之后,在粘贴出本节效果图配以完整代码,然后分拆之,个体技术剖析。这样既可以达到全局整体效果,也可以对局部技术或者知识点做以小结。功能看图描述:本程序开发基于C#+WPF,然后这些条件具备前需要安装office2010以上版本,包含OneNote即可

问题继续描述,未加入如上代码时,暂且不说批处理,即便是单处理。结果是无论加载多少张图片,可以生成对应txt文件,但是对应的所有txt文件里面文本内容始终一样。解决方案分析下:
3. 在读取xml中发现this.txtOCRed.Text = xml.First().ToString();那么让去每次读取最后一条数据不就ok?对,,肯定这样,抱着坚定信心解决半日不得解。断点再经调试发现,读取的xml是不可控的,即是缓存中xml以输出参数,输出的字符串的处理。最终还不得解决。为此困惑数日。
4. 那么在生成的缓存xml重新放置到新建的xml中,然后每次读取一条结束,删除本次记录。问题肯定解决的,大喜,于是做出如下构造:

结果还是无济于事,关键还是缓存的xml无法清理。
解决方案:搞定凌晨,无意间打开几篇英文文章(文章看不懂,只看代码),发现其原理在于图片处理过程中,催毁原始页面,新建页面即可。
var onenoteApp = new Microsoft.Office.Interop.OneNote.Application(); //onenote提供的API /***************************************************************************************/ string sectionID; onenoteApp.OpenHierarchy(@"C:\Users\Administrator\Documents\OneNote 笔记本\个人\newfile.one", null, out sectionID, Microsoft.Office.Interop.OneNote.CreateFileType.cftSection); string pageID = "{A975EE72-19C3-4C80-9C0E-EDA576DAB5C6}{1}{B0}"; onenoteApp.CreateNewPage(sectionID, out pageID, Microsoft.Office.Interop.OneNote.NewPageStyle.npsBlankPageNoTitle); /********************************************************************************/
调用API中创建页面方法CreateNewPage,pageID通过断点可以调试到,sectionID找到本地的地址即可。然后在执行一条数据结束时,调用onenoteApp.DeleteHierarchy(existingPageId)即可。
止于此核心问题解决,下面总结下所用的文件相关操作:
1 、验证文件夹是否存在,以及是否为空
#region 验证文件夹是否存在,以及是否为空 :2014-7-10 17:12:57 //验证文件夹是否存在,以及是否为空 //时间:2014-7-10 14:54:44 //作者:白宁超 private bool fn数据验证() { if ((bool)this.rbtn本地图片.IsChecked) { if (!Directory.Exists(this.txtfile.Text)) { this.labMsg.Content = "目录不存在,重新选择!"; this.txtfile.Focus(); return true; } System.IO.DirectoryInfo di = new System.IO.DirectoryInfo(@txtfile.Text); if (di.GetFiles().Length + di.GetDirectories().Length == 0) { this.labMsg.Content = "目录为空!"; this.txtfile.Focus(); return true; } } if (!Directory.Exists(this.txt输出目录.Text)) { this.labMsg.Content = "输出目录不存在,请重新选择。"; this.txt输出目录.Focus(); return true; } return false; } #endregion
2、遍历出文件中图片路径
#region 遍历出文件中图片路径 //文件中选择所有文件处理 //时间:2014-7-10 17:17:29 //作者:白宁超 public List<string> GetImgPath(string Filepath) { DirectoryInfo d = new DirectoryInfo(Filepath); ArrayList Flst = GetAll(d); //存放图片完整路径 List<string> imgpath = new List<string>(); foreach (object o in Flst) { imgpath.Add(@txtfile.Text + "\\" + o.ToString()); } return imgpath;//返回图片路径集合 } #endregion
3、获取图片的过程
#region 获取图片的过程 private void fnStartDownload(string v_strImgPath, string v_strOutputDir, out string v_strTmpPath) { int n = v_strImgPath.LastIndexOf('/'); string URLAddress = v_strImgPath.Substring(0, n); string fileName = v_strImgPath.Substring(n + 1, v_strImgPath.Length - n - 1); this.__OutputFileName = v_strOutputDir + "\\" + fileName.Substring(0, fileName.LastIndexOf(".")) + ".txt"; if (!Directory.Exists(System.Configuration.ConfigurationManager.AppSettings["tmpPath"])) { Directory.CreateDirectory(System.Configuration.ConfigurationManager.AppSettings["tmpPath"]); } string Dir = System.Configuration.ConfigurationManager.AppSettings["tmpPath"]; v_strTmpPath = Dir + "\\" + fileName; this.client.DownloadFile(v_strImgPath, v_strTmpPath); } #endregion
4、删除指定目录下的所有文件夹以及文件
#region//删除指定目录下的所有文件夹以及文件 private void DelFillOrDir(string strPath) { if (Directory.GetDirectories(strPath).Length > 0 || Directory.GetFiles(strPath).Length > 0) { // 获得文件夹数组 string[] strDirs = System.IO.Directory.GetDirectories(strPath); // 获得文件数组 string[] strFiles = System.IO.Directory.GetFiles(strPath); // 遍历所有子文件夹 foreach (string strFile in strFiles) { // 删除文件夹 System.IO.File.Delete(strFile); } // 遍历所有文件 foreach (string strdir in strDirs) { // 删除文件 System.IO.Directory.Delete(strdir, true); } } // 成功 } #endregion
5、删除文件
#region//删除文件 public static bool DeleteFile(string xmlPath) { FileInfo newFile = new FileInfo(xmlPath); if (newFile.Exists == true) { newFile.Delete(); return true; } else { return false; } } #endregion
6、删除xml数据

try { xe.Remove(); doc.Save(xpath); } catch { } } #region OCR写入Onenote和生成文字整个过程 //string xpath = @"C:\Users\Administrator\Desktop\OCR_Onenote\OnenoteOCR2.1\tmp.xml"; private void fnOCR(string v_strImgPath) { ORC(v_strImgPath); } public void ORC(string v_strImgPath) { FileInfo file = new FileInfo(v_strImgPath); #region //获取图片的Base64编码 using (MemoryStream ms = new MemoryStream()) { Bitmap bp = new Bitmap(v_strImgPath); switch (file.Extension.ToLower()) { case ".jpg": bp.Save(ms, ImageFormat.Jpeg);

#endregion //向Onenote2010中插入图片 var onenoteApp = new Microsoft.Office.Interop.OneNote.Application(); //onenote提供的API /***************************************************************************************/ string sectionID;

page.Root.SetAttributeValue("ID", existingPageId); //保存图片进入Onenote页面 //注意以下几点:(待解决) //1,onenote页面自动会生成一个页面,可能造成一直ocr错误。删除默认页面,新建空页 //2,图片存储在新建页面中,通过如下代码实现的,以追加存储方式进行。 onenoteApp.UpdatePageContent(page.ToString(), DateTime.MinValue); //线程休眠时间,单位毫秒,若图片很大,则延长休眠时间,保证Onenote OCR完毕 System.Threading.Thread.Sleep(Int32.Parse(System.Configuration.ConfigurationManager.AppSettings["WaitTIme"])); string pageXml; onenoteApp.GetPageContent(existingPageId, out pageXml, Microsoft.Office.Interop.OneNote.PageInfo.piBinaryData); //获取OCR后的内容 FileStream tmpXml = new FileStream(System.Configuration.ConfigurationManager.AppSettings["tmpPath"] + @"\tmp.xml", FileMode.Create, FileAccess.ReadWrite); StreamWriter sw = new StreamWriter(tmpXml); sw.Write(pageXml); sw.Flush(); sw.Close(); tmpXml.Close(); //加载xml中的数据 FileStream tmpOnenote = new FileStream(System.Configuration.ConfigurationManager.AppSettings["tmpPath"] + @"\tmp.xml", FileMode.Open, FileAccess.ReadWrite);

7、搜索文件夹中的文件
#region 搜索文件夹中的文件:2014-7-10 17:12:57 //搜索文件夹中的文件 //时间:2014-7-10 14:54:44 //作者:白宁超 ArrayList GetAll(DirectoryInfo dir) { try { ArrayList FileList = new ArrayList();//定义数组存放图片文件名 FileInfo[] allFile = dir.GetFiles(); foreach (FileInfo fi in allFile) { FileList.Add(fi.Name);//遍历图片,并添加到数组 } DirectoryInfo[] allDir = dir.GetDirectories(); foreach (DirectoryInfo d in allDir) { GetAll(d); } return FileList; } catch (Exception e) { labMsg.Content = e.Message + "文件夹选择方式错误,重新选择!!"; return null; } } #endregion
8、选择遍历文件夹图片
private void btn浏览_Click(object sender, RoutedEventArgs e) { txtmulu.Text = null; FolderBrowserDialog dialog = new FolderBrowserDialog(); dialog.Description = "请选择待处理目录"; if (dialog.ShowDialog() == System.Windows.Forms.DialogResult.OK) { string foldPath = dialog.SelectedPath; txtfile.Text = foldPath; DirectoryInfo d = new DirectoryInfo(@txtfile.Text); ArrayList Flst = GetAll(d); foreach (object o in Flst) { txtmulu.Text += "正在ORC图片: 【" + o.ToString() + "】\r\n"; } } else { labMsg.Content = "打开失败!!"; } #region 上传单个图片 2014-7-10 15:34:17 /*OpenFileDialog ofd = new OpenFileDialog(); ofd.Title = "请选择一个本地图片"; ofd.Multiselect = false; ofd.Filter = "支持的图片格式(*.jpg,*.jpeg,*.gif,*.bmp,*.png,*.tiff,*.emf)|*.jpg;*.jpeg;*.gif;*.bmp;*.png;*.tiff;*.emf"; if (ofd.ShowDialog() == System.Windows.Forms.DialogResult.OK) { this.txt本地图片.Text = ofd.FileName; this.img图片.Source = new BitmapImage(new Uri(ofd.FileName, UriKind.RelativeOrAbsolute)); this.labMsg.Content = "本地图片已成功加载。"; }*/ #endregion }
9、窗体关闭
private void Window_Closing(object sender, System.ComponentModel.CancelEventArgs e) { DirectoryInfo dir = new DirectoryInfo(System.Configuration.ConfigurationManager.AppSettings["tmpPath"]); foreach (FileInfo file in dir.GetFiles()) { file.Delete(); } }
【补充】orc前后结果对照:应部分园友建议,更为直观
【篇末】:程序中使用遍历文件,文件夹清空处理,文件的删除,文件的查找,文件夹的判空,重点在于图片的OneNote处理等操作,完成了批处理。可以自动执行批文件夹中图片,生成新的文本文件与图片名一致。现在不足之处,对文件夹的文件类型筛选为执行图片类型没有处理,容错不足,这个自己用文件放入纯图片可以,另外有时候进程处理不稳定,估计加入进度条原因。待版本2再做改进。下一节介绍文本文件处理入库(Oracle)。特别wpf中DataGrid的使用,如何在wpf中完成分页,简单的集合类型数据库分页可以,但是数据库连接如何分页?
