OpenCV最常用

OPENCV代码范例

#include "stdafx.h"

#include "opencv2/opencv.hpp"

#include "morphoFeatures.h"

#include <fstream>

using namespace std;

using namespace cv;

#ifdef _DEBUG

#pragma comment(lib,"lib/opencv_imgproc231d.lib")

#pragma comment (lib, "lib/opencv_core231d.lib")

#pragma comment (lib, "lib/opencv_highgui231d.lib")

#else

#pragma comment(lib,"lib/opencv_imgproc231.lib")

#pragma comment (lib, "lib/opencv_core231.lib")

#pragma comment (lib, "lib/opencv_highgui231.lib")

#endif

8-bit unsigned integer (uchar)

8-bit signed integer (schar)

16-bit unsigned integer (ushort)

16-bit signed integer (short)

32-bit signed integer (int)

32-bit ?oating-point number (?oat)

64-bit ?oating-point number (double)

num { CV_8U=0, CV_8S=1, CV_16U=2, CV_16S=3, CV_32S=4, CV_32F=5, CV_64F=6 };

注意:CV_32FC1 == CV_32F, CV_32FC2 == CV_32FC(2) == CV_MAKETYPE(CV_32F, 2)

cv::Vec3b：It is a vector of 3 unsigned chars.

 cv::Vec3i:      a 3-vector of integers     c = a +b;(都是Vec3i)

使用opencv编译release程序

大体上要注意一下几点内容:

1.vc++目录的选择上，库目录选择为opencv目录中的staticlib目录

2.在链接-》输入-》附加依赖库，中添加，相应的staticlib库目录中的所有条目

我使用的是opencv2.4.4包括一下内容：

IlmImf.lib

libjasper.lib

libjpeg.lib

libpng.lib

libtiff.lib

opencv_calib3d244.lib

opencv_contrib244.lib

opencv_core244.lib

opencv_features2d244.lib

opencv_flann244.lib

opencv_gpu244.lib

opencv_haartraining_engine.lib

opencv_highgui244.lib

opencv_imgproc244.lib

opencv_legacy244.lib

opencv_ml244.lib

opencv_nonfree244.lib

opencv_objdetect244.lib

opencv_photo244.lib

opencv_stitching244.lib

opencv_ts244.lib

opencv_video244.lib

opencv_videostab244.lib

Zlib.lib

可能还需要给代码上添加以下内容：

#pragma   comment(lib,   "vfw32.lib ")

#pragma comment (lib , "comctl32.lib")

3.在c/c++ --》代码生成--》运行库，选择，多线程/MT，即为静态库编译

参照上面的方法，对下面的教程，在vs2010中，编译出了release版本的程序

大概为3.22M大小，在不使用opencv其他dll 的库的情况下，可以直接在win32、64系统上使用
http://wiki.opencv.org.cn/index.php/%E4%BA%BA%E8%84%B8%E6%A3%80%E6%B5%8B
 4.最后需要注意的是，如果实在还是有问题，还有杀手锏，就是所有静态lib直接copy到相应的目录下面，完后编译链接，windows有时候就是找不到。。。！！！
