Windows上的Eclipse上的OpenCV [英] OpenCV on eclipse on windows

问题描述

我正在尝试在Windows上安装opencv，这是我的步骤:

I'm trying to install opencv on windows, here are my steps:

• 从网站上下载了opencv 2.4.3
• 运行exe，将文件夹提取到同一路径
• 打开的月食(先前已设置并配置了MinGW)
• 创建了新项目XYZ
• 添加了新文件夹"src"
• 添加了新类"main.cpp"

• 添加了以下代码:

• downloaded opencv 2.4.3 from website
• run the exe, extracted the folder in the same path
• opened eclipse (with MinGW previously set and configured)
• created new project XYZ
• added new folder "src"
• added new class "main.cpp"

• added the following code:

哈希包含< cv.h>
哈希包含< highgui.h>

hash include <cv.h>
hash include <highgui.h>

using namespace cv;
int main(int argc, char** argv) {

Mat image;
image = imread(argv[1], 1);

if (argc != 2 || !image.data) {
    printf("No image data \n");
    return -1;
}

namedWindow("Display Image", CV_WINDOW_AUTOSIZE);
imshow("Display Image", image);

waitKey(0);

return 0;
}

添加了两条路径

added the two paths

• "E:\ Sources \ opencv \ build \ include"
• "E:\ Sources \ opencv \ build \ include \ opencv"

请告知是否缺少任何步骤

Please advice if any step is missing

推荐答案

您将需要openCV 2.4.3的最新稳定版本.

you gonna need the latest stable version of openCV 2.4.3 .

Eclipse Juno！ (面向C/C ++开发人员的Eclipse IDE) 和 MinGW-适用于Windows的极简主义GNU

Eclipse Juno ! (Eclipse IDE for C/C++ Developers ) And MinGW - Minimalist GNU for Windows

我们将忽略x86/64的选择，因为我们将使用32编译器和32 openCV构建，即使系统是64编译器！

we will ignore x86/64 choice, since we gonna work with a 32 compiler / and 32 openCV build, even though the system is a 64 one !

第1步:下载并安装

Eclipse

从中下载Eclipse并解压缩归档文件. (我假设您的计算机上已经装有JRE，如果没有，请下载并安装它).

Download Eclipse from and decompress the archive . ( I assumed that you already have JRE on your computer , if not ! download and install it ) .

MinGW

下载MinGW.安装程序将引导您完成该过程！ 您可能必须将bin目录添加到路径中！ (默认路径:C/MinGW/bin)

Download MinGW . the installer will lead you through the process ! you might have to add the bin directory to the path ! (Default path : C/MinGW/bin )

OpenCV

从链接下载openCV exe，解压缩文件(在本教程的C:/目录中). 确保您具有下面的文件结构.

Download openCV exe from the link , extract the files (in the C:/ directory in this tutorial ) . Make sure you have the file structure below .

别忘了添加bin目录=>路径！

don't forget to add the bin directory => Path !

正如我之前提到的！即使我有64个操作系统，我也将使用x86构建，以避免编译器问题并使本教程向x86 OS用户开放！

As I mentioned earlier ! I'll use x86 build even if i have a 64 OS to avoid compiler problems and to keep this tutorial open to x86 OS users !

第2步:创建和配置

• 打开Eclipse IDE！
• 创建一个新的C ++项目:文件>新建> C ++项目
• 选择一个Hello Word项目以拥有一个预先构造的项目！ 不要忘记选择MinGW工具链

• Open the Eclipse IDE !
• Create a new C++ project : File > New > C++ Project
• Choose a Hello Word Project to have a pre structured one ! Don't forget to select the MinGW toolchains

点击完成"，开始工作！

Click Finish and let's get to work !

现在，您已经有了第一个Hello word项目！将Soure文件.cpp中的代码替换为下面的代码

Now that you have you first Hello word project ! replace the Code in the Soure file .cpp by the code below

///////////////CODE///////////

///////////////CODE///////////

#include "opencv2/highgui/highgui.hpp"
#include <iostream>
using namespace cv;
using namespace std;
int main(int argc, char** argv)
{
  Mat im = imread(argc == 2 ? argv[1] : "lenna.png", 1);
  if (im.empty())
  {
    cout << "Cannot open image!" << endl;
    return -1;
  }
  imshow("image", im);
  waitKey(0);
  return 0;
}

///////////////CODE///////////

///////////////CODE///////////

很明显，代码上存在多个错误，是的！我们必须链接库！

Obviously there are multiple errors on the code , yes ! we have to link the libraries !

现在转到属性>> C/C ++构建>>设置 在工具设置选项卡>> GCC C ++编译器>>包括和包括opencv路径中！ [opencvDir \ build \ include]

Now go to Properties >> C/C++ Build >> Settings on the Tool Setting tab >> GCC C++ Compiler >> Includes and include opencv path ! [opencvDir\build\include]

现在滚动到MinGW C ++ Linker >>库，并添加库搜索路径[opencvDIR \ build \ x86 \ mingw \ lib]

Now scroll to MinGW C++ Linker >> Libraries and add the Library search path [opencvDIR\build\x86\mingw\lib]

在图书馆部分！我们根据项目需要添加任意数量的librarie！ 在这里，我仅出于教程目的添加了4个库，即使只需要highgui一个库即可使我们的测试代码正常工作！ 这些库的名称可以在[opencvDIR \ build \ x86 \ mingw \ lib]中找到 例子 ！对于libopencv_video243.dll.a，请在链接器中添加opencv_video243！

in the Libraries part ! we add as much librarie as we need for the project ! here I added 4 libraries just for tutorial sake even if well need only the highgui one for our test code to work ! The libraries names can be found on the [opencvDIR\build\x86\mingw\lib] Example ! for libopencv_video243.dll.a wee add opencv_video243 in the linker !

单击确定"！

现在我们可以构建第一个项目！ 您认为必须像源代码"lenna.png"中所暗示的那样向项目添加图片. 使用莱娜带来好运

Now we can build our first project ! You figured that you have to add a picture to the project as implied in the source code "lenna.png" Use lenna for good luck

构建并运行项目！ 如果您看到漂亮的女士:)恭喜您:)

Build and Run the project ! If you see the beautiful lady :) Congrats :)
