OpenCV 之Hello world篇

Step1: 准备环境

OpenCV 在github上下载最新源码：https://github.com/Itseez/opencv

CMake 下载最新3.0 http://www.cmake.org/cmake/resources/software.html
VS2013

安装git

TBB 下载https://www.threadingbuildingblocks.org/ 线程构建模块

Step2: 借助CMake生成VS2013的解决方案

新建一个OpenCVLatest目录，然后用git clone 下最新的OpenCV 源码。

git clone https://github.com/Itseez/opencv.git[/code] 
在OpenCVLatest 目录下，新建一个build\buildvs2013x64 目录。

打开CMake软件，进行配置：

1)在Where is the source code => OpenCV的源代码

2)Where to build the binaries =>OpenCVLatest\build\buildvs2013x64

3)点击"Configure" 按钮，在弹出的对话框中，选择“Visual Studio 12 Win64”，使用默认的本地编译器，然后点击”Finish“

4) 勾选"WITH_TBB"  (滑动到底部)

并修改TBB_INCLUDE_DIRS 的值，为解压TBB的include目录。 ==> OpenCVLatest\tbb42_20140601oss\include

5) 点击"Configure" 按钮， 直至没有红色标记的出现。

6）点击”Generate“ 按钮，生成VS2013的工程。

Step3：编译OpenCV解决方案

打开OpenCV.sln,

选择CMakeTargets下的INSTALL 工程，点击生成Debug和Release版本的dll和lib库。

至此，编译就OK了。

PS:添加OpenCV环境变量，Value为：D:\android\workspace\OpenCVLatest\build\buildvs2013x64\install\x64\vc12

Step4: 新建VC++ win32 应用程序，工程名为：HelloWorldOpenCV

”右键“-> Configuration Properties -> Configuration Manager 新建解决方案平台，选择x64，其他默认；

在属性管理器中，选择Debug|x64, 新建OpenCV249_X64_Debug的属性表，然后进行如下配置：

HelloWorldOpenCV 的demo如下：

#include <opencv2/opencv.hpp>
#include <iostream>

using namespace std;
using namespace cv;

int main(int argc, char **argv)
{
Mat img = imread("2.jpg");
if (img.empty())
{
cout << "打开图像失败！" << endl;
return -1;
}
namedWindow("image", CV_WINDOW_AUTOSIZE);
imshow("image", img);
waitKey();

return 0;
}


如果没有其他问题，就可以正常运行，弹窗窗体显示图片了。

注意图片，放在C++ 源文件目录就可以了。

遇到的问题：

1） 提示tbb_debug.dll 找不到

解决方案：

把OpenCVLatest\tbb42_20140601oss\bin\intel64\vc12 目录下的tbb_debug.dll 文件拷贝到 OpenCVLatest\build\buildvs2013x64\install\x64\vc12\bin 目录即可。

2）无法启动，提示：

解决方法：

1. Ctrl + F5运行就可以了

2. 在cmd命令行下执行程序。

3. 把"Microsoft Symbol Servers"勾上(Tools -> Options -> Debugging -> Symbols).
