    篇四:关于OneNote入库处理以及审核:http://www.cnblogs.com/baiboy/p/wpf3.html


    【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。


    篇二:基于OneNote难点突破和批量识别

    【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

    功能以及操作描述:

    1. 运行本页面如上图,然后通过选择待处理目录(含中文文字图片),和输出目录,点击ORC即可。
    2. 在待处理目录下,点击浏览按钮,然后选择相应的文件夹,后台通过判断文件夹是否存在,如果存在进行遍历,读取出所有图片,然后在本页左端文本框对图片进行显示。
    3. 然后选择输出目录中的浏览按钮,选择处理后的结果存放文件夹,此项必填。否则不执行。在每次操作浏览按钮时,会对选择的文件夹进行清空处理,这样下次操作保持干净数据。
    4. 完成以上步骤,可以进行ORC操作,操作过程中通过遍历文件夹中图片文件,在一个方面中打开OneNote接口,对图片进行处理。图片处理生成的是一个xml文件,此文件不可视,一个缓存的xml文件,随着程序结束而终止,在处理过程中通过代码解析缓存xml,将文本数据提取到一个txt文件中。同时没执行一张图片,如图左边打印成功执行的文件,同时进度条滚动,结束后进行提示。
    5. 最后打开对应文件夹里面显示生产数据与对应图片保持一致。规范字体识别率还是可以的

    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:

    1. 是文本生成问题,于是想到每次图片生成清理出前一个xml,但是无论如何找不到xml存在,后来断点调试发现,执行onenoteApp.UpdatePageContent(page.ToString(), DateTime.MinValue);之后,打开Onenote页面会发现图片出来,说明onenote已经在处理,此刻xml已经生成。接下来 onenoteApp.GetPageContent(existingPageId, out pageXml, Microsoft.Office.Interop.OneNote.PageInfo.piBinaryData);方法把不可见的xml以字符串形式pageXml显示处理,后面就是对其处理了。证明从xml着手是不能解决问题的。
    2. 接下来就是想另一个方案:采用接口提供的DeletePageContent方法,但是面临问题在于其需要两个参数(页面序列id,和图片id),对于页面序列id通过断点可以找到,但是图片是随机的,id无法控制。因此此方案失败。

          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:UsersAdministratorDocumentsOneNote 笔记本个人
    ewfile.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:

    8、选择遍历文件夹图片

                FolderBrowserDialog dialog = new FolderBrowserDialog();

                    foreach (object o in Flst)
                    {
                        txtmulu.Text += "正在ORC图片: 【" + o.ToString() + "";
                    }
                }
                else

                    labMsg.Content = "打开失败!!";
                }

                }*/
                #endregion

    9、窗体关闭

            {
                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

    • 整体orc结果:

    • 具体orc结果:


    【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wpfDataGrid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?
