VS2012下安装配置OpenCV2.4.9的方法

来源：互联网发布：免费的读书软件编辑：程序博客网时间：2024/05/21 11:28

①安装VS2012，这里我就不再赘述了，相信大家都能找到下载地址，也都会安装
②下载Windows安装包OpeCV2.4.9并解压，这里我提供一个下载链接：http://pan.baidu.com/s/1slePknj，这里我的解压目录为：D:\Program_Files\opencv2.4.9 这个目录路径要知道，因为与下面的配置有关

③配置OpenCV2.4.9的环境变量(D:\Program_Files\opencv2.4.9\opencv\build\x86\vc11\bin),如下图所示

④新建一个Win32应用对口控制程序的空项目，然后按下面的截图配置

对于链接器输入的配置，debug版的Release版的配置分别如下:

debug版（实际上就是路径\opencv2.4.9\opencv\build\x86\vc11\lib 下面带d后缀的lib文件）
opencv_ml249d.lib
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_objdetect249d.lib
opencv_ts249d.lib
opencv_video249d.lib
opencv_nonfree249d.lib
opencv_ocl249d.lib
opencv_photo249d.lib
opencv_stitching249d.lib
opencv_superres249d.lib
opencv_videostab249d.lib

release版（实际上就是路径\opencv2.4.9\opencv\build\x86\vc11\lib 下面不带d后缀的lib文件
opencv_objdetect249.lib
opencv_ts249.lib
opencv_video249.lib
opencv_nonfree249.lib
opencv_ocl249.lib
opencv_photo249.lib
opencv_stitching249.lib
opencv_superres249.lib
opencv_videostab249.lib
opencv_calib3d249.lib
opencv_contrib249.lib
opencv_core249.lib
opencv_features2d249.lib
opencv_flann249.lib
opencv_gpu249.lib
opencv_highgui249.lib
opencv_imgproc249.lib
opencv_legacy249.lib
opencv_ml249.lib

值得注意的是：VS2012中debug版和Release版并没有窗口分别配置，也就是说在同一时刻你只能选择一种！这两种模式的切换方法可以参考我的博文http://blog.csdn.net/wenhao_ir/article/details/51482427

⑤输入以下源代码，编译，生成exe文件

//OpenCV版本2.4.9//交流QQ2487872782#include "opencv2/imgproc/imgproc.hpp"#include "opencv2/highgui/highgui.hpp"int main( ){// 读取源图像并转化为灰度图像cv::Mat srcImage = cv::imread("flower.jpg");// 判断文件是否读入正确if( !srcImage.data ) return 1;// 图像显示cv::imshow("srcImage", srcImage);// 等待键盘键入cv::waitKey(0);return 0;}

⑥把图片flower.jpg放到下图中的位置(图片下载链接:http://pan.baidu.com/s/1bo0GjD1)

⑦运行及结果如下图所示:
