新手OpenCV2.4.9运行SURF跳错debug assertion failed。

Question

百度上说时野指针或者内存溢出，怎么解决？
#include "stdafx.h"
#include

#include
using namespace cv;
using namespace std;

int main(int argc, char** argv)
{
system("color 6F");

Mat trainImage = imread("1.jpg"), trainImage_gray;
imshow("原始图", trainImage);
cvtColor(trainImage, trainImage_gray, CV_BGR2GRAY);

//检测surf关键点，提取训练图像描述符
vector<KeyPoint>train_keyPoint;
Mat trainDescriptor;
SurfFeatureDetector featureDetector(80);
featureDetector.detect(trainImage_gray, train_keyPoint);
SurfDescriptorExtractor featureExtractor;
featureExtractor.compute(trainImage_gray, train_keyPoint, trainDescriptor);

//创建基于FLANN的描述符匹配对象
FlannBasedMatcher matcher;
vector<Mat> train_desc_collection(1, trainDescriptor);
matcher.add(train_desc_collection);
matcher.train();

//创建视屏对象、定义帧率
VideoCapture cap(0);
unsigned int frameCount = 0;//帧数

vector<KeyPoint> test_keyPoint;
vector<vector<DMatch>> matches;
vector<DMatch> goodMatches;
//不断循环直到q键被按下
while (char(waitKey(1)) != 'q')
{
    //<1>参数设置
    int64 time0 = getTickCount();
    Mat testImage, testImage_gray;
    cap >> testImage;//采集视屏到testImage中
    if (testImage.empty())
    {
        continue;
    }
    //<2>转化图像到灰度
    cvtColor(testImage, testImage_gray, CV_BGR2GRAY);
    //<3>检测S关键点、提取测试图像描述符
    Mat testDescriptor;
    featureDetector.detect(testImage_gray, test_keyPoint);
    featureExtractor.compute(testImage_gray, test_keyPoint, testDescriptor);

    //<4>匹配训练和测试描述符
    matcher.knnMatch(testDescriptor, matches, 2);
    //<5>根据劳氏算法得到优秀的匹配点
    for (unsigned int i = 0; i < matches.size(); i++)
    {
        if (matches[i][0].distance < 0.6 * matches[i][1].distance)
            goodMatches.push_back(matches[i][0]);
    }

    //<6>绘制匹配点并显示窗口
    Mat dstImage;
    drawMatches(testImage, test_keyPoint, trainImage, train_keyPoint, goodMatches, dstImage);
    imshow("匹配窗口", dstImage);

    cout << "当前帧率为:" << getTickFrequency() / (getTickCount() - time0) << endl;
    test_keyPoint.clear();
    matches.clear();
    goodMatches.clear();
}
return 0;

}

你罗列了这么一大堆代码，不知道是哪行出的问题啊。你单步，然后把运行到那一行的代码指出来，这样大家可能会有针对性的看了~
