【中文标题】薄板样条形状变换运行时错误 [退出，代码 -1073741819]

【问题描述】：

我一直在尝试使用 opencv 3.1.0、Shape Tranformation 类扭曲图像。具体来说，就是薄板Sline算法

（我实际上尝试了Shape Transformers and Interfaces OpenCV3.0的一段代码）

但问题是我一直在控制台说运行时错误

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

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

我搜索了运行时错误，说可能是dll问题，但我一般运行opencv没有问题。我在运行形状变换算法时遇到错误，特别是 estimateTranformation 函数。

#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;

我只是希望能够运行该算法，以便检查它是否是我想要的算法。

请帮忙。

谢谢。

opencv 版本 3.1.0

IDE：Visual Studio 2015

操作系统：Windows 10

【参考方案1】：

尝试添加

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

在estimateTransformation()之前。
