一、解析文件依赖程序

Config.h 

 1 #pragma once
 2 #include<iostream>
 3 #include<vector>
 4 #include<opencv2\opencv.hpp> 
 5 class Config
 6 {
 7 public:
 8     Config();
 9     ~Config();

11 public:
12 
13     std::vector<std::string> GetString_Vec(cv::FileStorage fs, std::string sName);
14     std::vector<cv::Point> GetPoint_Vec(cv::FileStorage fs, std::string sName);
15     std::vector<int> GetNum_Vec(cv::FileStorage fs, std::string sName);
16     cv::Point GetPoint(cv::FileStorage fs, std::string sName);

案例依赖的结构体信息

 1 struct strYml
 2 {
 3     const std::string sWidth = "sWidth";
 4 
 5     const std::string calibPt = "sCalibPt";
 6 
 7     const std::string sPts = "sPts";

 9     const std::string sET = "sET";
10 
11     const std::string strCom = "strCom";
12 
13     const std::string sModeName = "sModeName";
14 
15     const std::string sModePath = "sModePath";
16 
17     const std::string sModeImg = "sModeImg";
18 
19 };
20 
21 struct outYmlStr
22 {
23     int iWidth; //像素宽度
24 
25     cv::Point calibPt; //标定点
26 
27     std::vector<cv::Point>pts; //偏移量
28 };
29 
30 struct paraSet
31 {
32     double exploreTime;  //曝光时间
33 
34     std::string strCom; //串口端口号
35 
36     std::string sModeFileName;  //模板名称
37 
38     std::string sModePath; //模板文件保存路径
39 
40     std::string sModeImgPath; //模板图像名称
41 };

Read YML

 2 {
 3     strYml sYmlConfig;
 4     FileStorage fs(sConfigPath, FileStorage::READ); //FileStorage::READ 读或写
 5     paraSets.exploreTime = sConfig.GetNum(fs, sYmlConfig.sET);
 6     paraSets.sModeFileName = sConfig.GetString(fs, sYmlConfig.sModeName);
 7     paraSets.sModeImgPath = sConfig.GetString(fs, sYmlConfig.sModeImg);
 8     paraSets.sModePath = sConfig.GetString(fs, sYmlConfig.sModePath);
 9     paraSets.strCom = sConfig.GetString(fs, sYmlConfig.strCom);
10 
11     //读取模板图像
12     cv::Mat mMode = cv::imread(paraSets.sModeImgPath);
13     std::string sModeYml = paraSets.sModePath;
14     FileStorage fR(sModeYml, FileStorage::READ); //FileStorage::READ 读或写
15     modeStruct.calibPt = sConfig.GetPoint(fR, sYmlConfig.calibPt);
16     modeStruct.iWidth = sConfig.GetNum(fR, sYmlConfig.sWidth);
17     modeStruct.pts = sConfig.GetPoint_Vec(fR, sYmlConfig.sPts);
18

Write YML

Write依赖的函数

 1 template<typename T> void WArrayToYml(cv::FileStorage fs, std::string sName, T& a)
 2 {
 3     fs << sName << "[";
 4     for (int i = 0; i < a.size(); i++)
 5     {
 6         fs << a[i];
 7     }
 8 
 9     fs << "]";
10 
11 }
12 //写元素
13 template<typename T> void  WValueToYml(cv::FileStorage fs, std::string sName, T& a)
14 {
15     fs << sName << a;
16 }

案例

1 void bWriteModeStruct(std::string sModePath,const outYmlStr& modeStruct)
2 {
3     FileStorage fs(sModePath, FileStorage::WRITE); //FileStorage::READ 读或写
4     strYml outStr;
5     WValueToYml(fs, outStr.sWidth, modeStruct.iWidth);
6     WValueToYml(fs, outStr.calibPt, modeStruct.calibPt);
7     WArrayToYml(fs, outStr.sPts, modeStruct.pts);
