使用OPENCV图像处理库，将图片裁剪分屏显示

复制代码 代码如下:

//#include "stdafx.h"

#include <opencv2/opencv.hpp>

//#include <opencv2/imgproc/imgproc.hpp>

//#include <opencv2/highgui/highgui.hpp>

#include <iostream>

#include <vector>

using namespace std;

using namespace cv;

//剪切图片为m * n 块

void Cut_img(Mat src_img,int m,int n,Vector<Mat> ceil_img)

{

int t = m * n;

int height = src_img.rows;

int width = src_img.cols;

int ceil_height = height/m;

int ceil_width = width/n;

Mat roi_img,tmp_img;

Point p1,p2;

for(int i = 0;i<m;i++)

for(int j = 0;j<n;j++){

//p1 =

Rect rect(i+j*ceil_width,j+i*ceil_height,ceil_width,ceil_height);

src_img(rect).copyTo(roi_img);

ceil_img.push_back(roi_img);

imshow("roi_img",roi_img);

//rectangle(i+j*ceil_width,j+i*ceil_height,);

}

waitKey(0);

}

void show_images(Vector<Mat> imgs,int n){

//do something

}

int main()

{

Mat img = imread("airplane.jpg",1);

imshow("src img",img);

int m = 3;

int n = 3;

Vector<Mat> ceil_img = m*n;

Cut_img(img,m,n,ceil_img);

waitKey();

return 0;

}

编译命令： g++ -ggdb `pkg-config --cflags opencv` -o ImageTake ImageTake.cpp `pkg-config --libs opencv`;
