Win10+VS2015+Opencv3.45 处理照片曝光融合时报错

Question

因项目要对照片进行优化，觉得C++与OpenCV的处理方案最优，但平时不用C++，不太熟悉，现在在运行网上一DEMO时过不去，弄不懂是OpenCV版本问题给还是配置问题，烦请有经验的老大给看看。

环境：Win10+VS2015+OpenCV3.45



查了不少资料，代码应该没有问题，但在调用OpenCV两个关键位置时一直报错：



0x00007FFE83A7A839 处(位于 ConsoleApplication3.exe 中)有未经处理的异常: Microsoft C++ 异常: std::length_error，位于内存位置 0x0000000CAEAFEA60 处。

//图像映射
Ptr alignMTB = createAlignMTB();
alignMTB->process(images, images);



// Merge using Exposure Fusion 图像融合
Mat exposureFusion;
Ptr mergeMertens = createMergeMertens();
mergeMertens->process(images, exposureFusion);



以下是完整代码：

#include "opencv2/photo.hpp"
#include "opencv2/imgcodecs.hpp"
#include "opencv2/highgui.hpp"

#include <iostream>
#include <vector>
#include <fstream>
using namespace cv;
using namespace std;

// Read Images
void readImages(vector<Mat> &images)
{
    int numImages = 16;
    static const char* filenames[] =
    {
        "./image/memorial0061.jpg",
        "./image/memorial0062.jpg",
        "./image/memorial0063.jpg",
        "./image/memorial0064.jpg",

        "./image/memorial0076.jpg"
    };
    //读图
    for (int i = 0; i < numImages; i++)
    {
        Mat im = imread(filenames[i]);
        images.push_back(im);
    }
}

int main()
{

    // Read images 读取图像
    cout << "Reading images ... " << endl;

    vector<Mat> images;

    //是否图像映射
    bool needsAlignment = true;

    // Read example images 读取例子图像
    readImages(images);
    //needsAlignment = false;

    // Align input images
    if (needsAlignment)
    {
        cout << "Aligning images ... " << endl;
        Ptr<AlignMTB> alignMTB = createAlignMTB();
        alignMTB->process(images, images);
    }
    else
    {
        cout << "Skipping alignment ... " << endl;
    }

    // Merge using Exposure Fusion 图像融合
    cout << "Merging using Exposure Fusion ... " << endl;
    Mat exposureFusion;
    Ptr<MergeMertens> mergeMertens = createMergeMertens();
    mergeMertens->process(images, exposureFusion);

    // Save output image 图像保存
    cout << "Saving output ... exposure-fusion.jpg" << endl;
    imwrite("exposure-fusion.jpg", exposureFusion * 255);

    waitKey(0);

    return 0;

}

一般来说是流或者指针没有初始化
