Question

我一直在尝试使用opencv 3.1.0 Shape Tranformation类变形图像。具体来说，薄板线算法

（我实际上尝试了Shape Transformers and Interfaces OpenCV3.0中的代码块）

但是问题是，我一直在用控制台说“ getting runtime time error”

D：\ Project \ TPS_Transformation \ x64 \ Debug \ TPS_Transformation.exe（进程13776）已退出，代码为-1073741819

我发现导致错误的代码是 tps->estimateTransformation(source, target, matches); 这是第一次执行转换算法的部分。

我搜索了运行时错误，指出可能是dll问题，但一般来说运行opencv都没有问题。运行形状转换算法（特别是estimateTranformation函数）时出现错误。

#include <iostream>

#include <opencv2\opencv.hpp>
#include <opencv2\imgproc.hpp>
#include "opencv2\shape\shape_transformer.hpp"

using namespace std;
using namespace cv;

int main()
{

    Mat img1 = imread("D:\\Project\\library\\opencv_3.1.0\\sources\\samples\\data\\graf1.png");


    std::vector<cv::Point2f> sourcePoints, targetPoints;
    sourcePoints.push_back(cv::Point2f(0, 0));
    sourcePoints.push_back(cv::Point2f(399, 0));
    sourcePoints.push_back(cv::Point2f(0, 399));
    sourcePoints.push_back(cv::Point2f(399, 399));

    targetPoints.push_back(cv::Point2f(100, 0));
    targetPoints.push_back(cv::Point2f(399, 0));
    targetPoints.push_back(cv::Point2f(0, 399));
    targetPoints.push_back(cv::Point2f(399, 399));

    Mat source(sourcePoints, CV_32FC1);
    Mat target(targetPoints, CV_32FC1);
    Mat respic, resmat;

    std::vector<cv::DMatch> matches;
        for (unsigned int i = 0; i < sourcePoints.size(); i++)
            matches.push_back(cv::DMatch(i, i, 0));

    Ptr<ThinPlateSplineShapeTransformer> tps = createThinPlateSplineShapeTransformer(0);
    tps->estimateTransformation(source, target, matches);
    std::vector<cv::Point2f> transPoints;
    tps->applyTransformation(source, target);

    cout << "sourcePoints = " << endl << " " << sourcePoints << endl << endl;
    cout << "targetPoints = " << endl << " " << targetPoints << endl << endl;
    //cout << "transPos = " << endl << " " << transPoints << endl << endl;
    cout << img1.size() << endl;

    imshow("img1", img1); // Just to see if I have a good picture

    tps->warpImage(img1, respic);

    imshow("Tranformed", respic); //Always completley grey ?
    waitKey(0);

    return 0;
}

我只希望能够运行算法，以便可以检查它是否是我想要的算法。

请帮助。

谢谢。

Answer 1

尝试添加

transpose(source, source);
transpose(target, target);

在估算Transformation（）之前。
