[opencv]1.环境配置篇

1.下载opcv源码

2.下载到本地之后，双击EXE文件，设置解压目录：

3.解压完成之后，接着设置windows环境变量：

4.新建工程名OpenTest的空C/C++项目，添加依赖库：

opencv_calib3d249d.lib
opencv_contrib249d.lib
opencv_core249d.lib
opencv_features2d249d.lib
opencv_flann249d.lib
opencv_gpu249d.lib
opencv_highgui249d.lib
opencv_imgproc249d.lib
opencv_legacy249d.lib
opencv_ml249d.lib
opencv_nonfree249d.lib
opencv_objdetect249d.lib
opencv_ocl249d.lib
opencv_photo249d.lib
opencv_stitching249d.lib
opencv_superres249d.lib
opencv_ts249d.lib
opencv_video249d.lib
opencv_videostab249d.lib

6.新建main.cpp输入以下内容：

include <iostream>

include "opencv2/core/core.hpp"

include "opencv2/highgui/highgui.hpp"

using namespace cv;
int main()
{
// 读入一张图片
Mat img = imread("pic.png");
// 创建窗口
namedWindow("pic");
// 在窗口中显示图片
imshow("pic", img);
// 等待60000 ms后窗口自动关闭
waitKey(60000);
}

7.图片的路径如下：

8.因为本文使用的win10系统是64位，所以platform也要改成64位的。

9.点击运行，效果如下图所示：
