opencv学习-1.1-入门- 显示图片

 

 

今天继续我们的OpenCV旅行

 首先： 准备环境吧；我的开发目录在F盘

    首先用CMAKE生成VS2008工程文件，我们所有的都是Debug版本

F:/devCenter_B/OpenCV/src/OpenCV/vs2008/OpenCV.sln

Build一下生成路径如下：

   头文件，以后应用会用到

  ./../../OpenCV/include/opencv;

./../../OpenCV/modules/core/include;

./../../OpenCV/modules/highgui/include;

./../../OpenCV/modules/imgproc/include;

./../../OpenCV/modules/video/include;

./../../OpenCV/modules/features2d/include;

./../../OpenCV/modules/flann/include;

./../../OpenCV/modules/calib3d/include;

./../../OpenCV/modules/objdetect/include;

./../../OpenCV/modules/legacy/include

//库文件-以后会用到

opencv_calib3d220d.lib opencv_contrib220d.lib opencv_core220d.lib opencv_features2d220d.lib opencv_ffmpeg220d.lib opencv_flann220d.lib opencv_gpu220d.lib opencv_haartraining_engine.lib opencv_highgui220d.lib opencv_imgproc220d.lib opencv_legacy220d.lib opencv_ml220d.lib opencv_objdetect220d.lib opencv_ts220d.lib opencv_video220d.lib

 

让我们显示图像吧

用VS2008创建一个工程

F:/devCenter_B/OpenCV/src/LoadImage/LoadImage.sln

 

OpenCV演示程序都是命令行，偶们就不要用了，直接IDE模式吧，简单点，没有必要和自己过不去

  在工程包含自己的文件和库（这步不会的去google吧，我不打算介绍IDE怎么用）

开始写点基本的代码，好久不写代码了，使用方式直线下降

 #include "stdafx.h"

#include "cv.h"

#include "highgui.h"

 

BOOL ShowImage(char *path, char *name);

 

int _tmain(int argc, char* argv[])

{

     // 偷懒写法，BS

     char *path = "F://devCenter_B//OpenCV//src//LoadImage//Debug//lena.jpg";

     ShowImage(path, NULL);

    return 0;   

}

BOOL ShowImage(char *path, char *name)

{

     IplImage *img;

     img = cvLoadImage(path, 1); 

       

    cvNamedWindow( "Image view", 1 );

    cvShowImage( "Image view", img );

 

    cvWaitKey(0); // 非常重要，内部包含事件处理循环

 

    cvReleaseImage( &img );

     cvDestroyWindow( "Image view" );

 

     return TRUE;

}
