OpenCV3.2.0配置 for VS2015

OpenCV3.2.0的配置

1. 安装VS2015，下载并解压OpenCV3.2.0

Note：OpenCV3.2.0自带的只有x64，x86需要自己编译。下面仅以x64为例配置。

2. 建立一个C++控制台空项目：

2.0 打开属性管理器：视图->其他窗口->属性管理器。

2.1 在 VC++目录->包含目录 填入：

X:\opencv\build\include\opencv2
X:\opencv\build\include\opencv
X:\opencv\build\include

2.2 在 VC++目录->库目录 填入：

X:\opencv\build\x64\vc14\lib

2.3 在 链接器->输入->附加依赖项 填入：

opencv_world320.lib（适用于“Release”）或
opencv_world320d.lib（适用于“Debug”）

3. 运行时，若提示错误丢失opencv_word320.dll：

将opencv的路径加到系统的路径变量中：计算机->（右键）属性->高级系统设置->高级（标签）->环境变量，在PATH中加入。

或者，在命令行中输入（各值间用英文分号“;”作为分隔符）：

set PATH=F:\opencv\build\x64\vc14\bin;%PATH%

并重启电脑即可。

测试样例：

#include <iostream>
#include <opencv.hpp>

using namespace cv;
using namespace std;

static Mat onAffine(Mat* im, Point2f dif);
static Mat onRot(int pos, int rat, Mat* im);
static void onMouse(int Event, int x, int y, int drag, Mat* im);

void main(int argc, char* argv[])
{
    Mat Cam = imread("Girl.png"), dst;
    int pos = 36, rat = 10, hes = 40; //initial value
    namedWindow("Video");
    createTrackbar("Angle", "Video", &pos, 72); //rotate the image
    createTrackbar("Scale", "Video", &rat, 20); //scale the image
    setMouseCallback("Video", (MouseCallback)onMouse, &Cam); //drag image

    while ((waitKey(50) & 255) != 13)
    {//press the Enter key to exit the programe
        dst = onRot(pos, rat, &Cam);    imshow("Video", dst);
    }//end while
}//end main

static void onMouse(int Event, int x, int y, int drag, Mat* im)
{
    static Mat res = im->clone();   static const Point ini(0, 0);
    static Point seed(ini), tdf(ini);   Point now(x, y);

    switch (Event)
    {
    case CV_EVENT_LBUTTONDOWN:  seed = now; break;
    case CV_EVENT_LBUTTONUP:    tdf += (now - seed);  break;
    case CV_EVENT_RBUTTONUP:    res.copyTo(*im);    tdf = ini;  break;
    }//end switch

    if (drag == CV_EVENT_FLAG_LBUTTON) //drag the mouse to move the image
        *im = onAffine(&res, tdf + (now - seed)); //use Affine transformation
}//end onMouse

static Mat onAffine(Mat* im, Point2f dif)
{
    Point2f org[3], tri[3];  org[1] = Point2f(im->cols / 2, 0);
    org[0] = Point2f(0, 0);  org[2] = Point2f(0, im->rows / 2);
    for (int i = 0; i<3; ++i)  tri[i] = org[i] + dif;

    Mat warp = getAffineTransform(org, tri), dst;
    warpAffine(*im, dst, warp, im->size()); return dst;
}//end onAffine

static Mat onRot(int pos, int rat, Mat* im)
{
    Point center(im->cols/2.0 + 0.5, im->rows/2.0 + 0.5);
    double angle = 5 * pos - 180, scale = 0.1*rat;
    Mat rot = getRotationMatrix2D(center, angle, scale), dst;
    warpAffine(*im, dst, rot, im->size());  return dst;
}//end onRot

备注：

OpenCV3.2移除了默认的SURF和SIFT库，放到了OpenCV的extra modules（即opencv_contrib）中。
SURF和SIFT的源码，参见：
https://github.com/opencv/opencv_contrib/tree/master/modules/xfeatures2d/src

如何编译opencv_contrib，参见：
