背景
2.开发的原因是因为需要扫描A、B、C。。多种文档然后放入不同的文件夹并且修改文件名。有些打印机具有编程功能，可以设定文件夹名称，但是还是需要人工修改文件名，扫描过程中还必须停下来。
3.想过很多ORC的方式来解决如何区分ABC文件的办法，但是速度慢并且效果差。
4.最后解决办法很简单，扫完A之后扫描一张纯色的图片，然后随机几个点判断是否是这个颜色，如果是则确定A文档已扫描完成，然后扫描B，同理。
5.在用高拍仪、摄像头的时候会因为现场光源影响图片的扫描结果，所以需要设定一个颜色区间。
6.效果奇好，识别达到100%
功能
1.把要扫描的文档扫描到一个文件夹里面
2.设定图片关联的数据，用程序进行处理
3.输出结果
关键代码
1.动作锦囊
using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Data; using System.Text.RegularExpressions; using System.IO; using REP = DAL.ImgScan.Repository; using FrameWork; using System.IO; using System.ComponentModel; namespace DAL.ImgScan { public class ActionModual { public static void ExcuteAction(REP.RowRecord rowRec, List<REP.Action> acRecs, REP.GeneralSetting genRec, REP.AdvanceSetting advRec, string rootPath) { foreach (var acRec in acRecs) { string folderPath = ActionModual.GetFolderPath(rowRec, rootPath + "\" + acRec.SavePath, advRec); string partOfSavePath = folderPath + "\" + Common.GetParamString(rowRec, acRec.JoinName); if (acRec.isFixed) { for (int i = 0; i < int.Parse(acRec.Amount); i++) { CopyFile(rowRec.imgFiles[i], folderPath, partOfSavePath + "$" + (i + 1).ToString() + ".jpg"); } rowRec.imgFiles.RemoveRange(0, int.Parse(acRec.Amount)); } else { for (int i = 0; i < rowRec.imgFiles.Count; i++) { CopyFile(rowRec.imgFiles[i], folderPath, partOfSavePath + "$" + (i + 1).ToString() + ".jpg"); } } } } public static List<REP.ParamInfo> CheckFileExist(List<REP.RowRecord> rowRecs, List<REP.Action> acRecs, REP.AdvanceSetting advRec) { int imgNm = 0; List<REP.ParamInfo> paramInfoes = new List<Repository.ParamInfo>(); foreach (var acRec in acRecs) { imgNm += int.Parse(acRec.Amount); } foreach (var rowRec in rowRecs) { if (imgNm > rowRec.imgFiles.Count) { paramInfoes.Add(new Repository.ParamInfo("图片数量小于动作设定所需图片数量", rowRec.value[advRec.oid])); } } return paramInfoes; } public static string GetFolderPath(REP.RowRecord rowRec, string rootPath, REP.AdvanceSetting advRec) { if (advRec.isChildFolder) { string childFolderPath = Common.GetParamString(rowRec, advRec.ChildFieldName); return rootPath + "\" + childFolderPath; } else { return rootPath; } } private static void CopyFile(string sourceFileName, string folderPath, string saveFullName) { if (!Directory.Exists(folderPath)) { Directory.CreateDirectory(folderPath); } if (!File.Exists(saveFullName)) { File.Copy(sourceFileName, saveFullName); } } } }
2.图像识别
using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Drawing; using System.Drawing.Imaging; using REP = DAL.ImgScan.Repository; namespace DAL.ImgScan { public class PhotoIdentify { public static bool CheckImg(string path) { using (Bitmap img = new Bitmap(path)) { int iRes = 0; int iY = img.Height / 3; int iX = img.Width / 8; for (int i = 1; i < 5; i++) { if (i == 2)//余下2个到纸的另一边取 { iY = iY * 2; } Color pixel = img.GetPixel(iX * i, iY + i * 2);// if (isTagImg(pixel)) { iRes++; } } if (iRes > 2) { return true; } else { return false; } } } public static List<REP.ParamInfo> ColorPicker(string folderPath) { List<REP.ParamInfo> paramInfoes = new List<REP.ParamInfo>(); string[] files = System.IO.Directory.GetFiles(folderPath, "*.jpg"); for (int j = 0; j < files.Length; j++) { using (Bitmap img = new Bitmap(files[j])) { for (int i = 0; i < 5; i++) { Color pixel = img.GetPixel(50 + i * 50, 200 + i * 2); paramInfoes.Add(new REP.ParamInfo(System.IO.Path.GetFileName(files[j]), "r:" + pixel.R + ";g:" + pixel.G + ";b:" + pixel.B)); } } } return paramInfoes; } private static bool isTagImg(Color pixColor) { if (pixColor.G - pixColor.R > 20 && pixColor.G > pixColor.B) { return true; } else { return false; } } } }
3.执行函数
