opencv之重映射

好久没写呆码了

今天发个重映射

#include "opencv2/video/tracking.hpp"

using namespace std;

int main()

{

    //【0】变量定义

    Mat srcImage,dstImage,img;

    Mat map_x, map_y;

    VideoCapture capture();

    while ()

    {

        //【1】载入原始图

        capture >> srcImage;

        imshow("原始图", srcImage);

        //【2】创建和原始图一样的效果图，x重映射图，y重映射图

        dstImage.create(srcImage.size(), srcImage.type());

        map_x.create(srcImage.size(), CV_32FC1);

        map_y.create(srcImage.size(), CV_32FC1);

        //【3】双层循环，遍历每一个像素点，改变map_x & map_y的值

        for (int j = ; j < srcImage.rows; j++)

        {

            for (int i = ; i < srcImage.cols; i++)

            {

                //改变map_x & map_y的值.

                map_x.at<float>(j, i) = static_cast<float>(i);

                map_y.at<float>(j, i) = static_cast<float>(srcImage.rows - j);

            }

        }

        remap(srcImage, dstImage, map_x, map_y, INTER_LINEAR, BORDER_CONSTANT, Scalar(, , ));

        imshow("【程序窗口】", dstImage);

        waitKey();

    }

    return ;
