OpenCV 第一课(安装与配置)
win10，opencv-2.4.13， 安装， vs2013， 配置
下载安装软件
官网OpenCV下载地址下载最新版本，我下载的是opencv.2.4.13,然后解压安装，我写的路径是D:\Program Files。注意本文中绿色标注的要换成你自己的安装路径。
这里得说一点，可能是因为网速太差的原因，昨天晚上下载了几次安装时都提示说“cannott open file‘opencv-2.4.13.exe‘ as archive”。我当时一直不明白是怎么回事，网上中文说这个原因的几乎没有，可能大家觉得这种问题不是问题吧。
OpenCV Windows install: can not open file “OpenCV-2.4.5.exe” as archive
后来发现是因为网速的原因下载的包总是不全，虽然无论下载多少图标显示都是一样的，但一定要注意下载后的大小是不是和网上安装包大小一样，以确定你下的包完整。
配置环境变量
win10 专业版，系统 -> 高级系统设置 -> 环境变量.

在用户变量中新建变量: opencv, 变量值 : D:\Program Files\opencv\build

在用户变量中选择"path"(不区分大小写)，点击“编辑”，在其末尾添加 ‘;D\Program Files\opencv\build\x86\vc12\bin‘,这里分号不能省略
如果用户变量中没有"path"，则新建变量:"path"，变量值:‘D:\Program Files\opencv\build\x86\vc12\bin‘

注：无论你是64位还是32位系统，上面路径都使用x86
至此环境变量配置完毕。此时需重启电脑或注销电脑，使环境变量生效。
编写属性表
打开记事本，分别创建两个文本"opencvdebug.props"和"opencvrelease.props",其中对应的内容如下，可以直接拷贝过去，但注意其中‘IncludePath’和“LibraryPath”中的“D:\Program Files”要修改为自己opencv安装路径。

配置VS2013
打开VS2013，文件 -> 新建 -> 项目，新建控台应用程序test
1474634781916.jpg
分别添加上两步创建的属性表
1474635625690.jpg
1474635448340.jpg
此处添加"opencvdebug.props"
1474635513018.jpg
此处添加"opencvrelease.props"
OK,VS2013现在就配置好了，写一个例子试验一下
测试
在源文件写入下面代码，你可以复制过去
- #include<cv.h>
- #include<highgui.h>
- int main(int argc, char** argv[])
- {
- IplImage* src = cvLoadImage("F:\\Programming\\C#\\Others\\test\\test\\timg.jpg", CV_LOAD_IMAGE_GRAYSCALE);
- cvNamedWindow("Src", CV_WINDOW_AUTOSIZE);
- cvShowImage("Src", src);
- cvWaitKey(0);
- cvReleaseImage(&src);
- cvDestroyAllWindows();
- return 0;
- }
其中图片路径自己选择。
结果：
1474635736652.jpg
之后再每次使用opencv创建工程之后分别将上述两个属性表导入就可以了。
