我正在寻找汉明距离帮助下的视频差异。这里是我的代码:OpenCV.norm中的声明错误
#include <iostream>
#include "opencv2/opencv.hpp"
using namespace cv;
int main(int argc, char** argv)
{
char const* filename = ("video.mp4");
VideoCapture video(filename);
Mat frame, temp;
for(unsigned int i = 0; i<100; i++)
{
video >> frame;
if (i > 0)
{
double dist = norm(frame, temp, NORM_HAMMING);
cout<<"Dist= "<< dist <<endl;
}
temp = frame;
}
return 0;
}
的问题是,在
double dist = norm(frame, temp, NORM_HAMMING);
程序降至
**OpenCV Error**: Assertion failed (normType == NORM_INF || normType == NORM_L1 || normType == NORM_L2 || normType == NORM_L2SQR || ((normType == NORM_HAMMING || normType == NORM_HAMMING2) && src1.type() == CV_8U))in norm, in file /home/andrio/.local/share/Trash/files/build/OpenCV/modules/core/src/stat.cpp, line 3123 terminate called after throwing an instance of 'cv::Exception' what(): /home/andre/.local/share/Trash/files/build/OpenCV/modules/core/src/stat.cpp:3123: error: (-215) normType == NORM_INF || normType == NORM_L1 || normType == NORM_L2 || normType == NORM_L2SQR || ((normType == NORM_HAMMING || normType == NORM_HAMMING2) && src1.type() == CV_8U) in function norm
UPD:此代码的工作:
double dist = norm(frame, temp, NORM_L2);
那么,当您调用该函数时,“帧”矩阵的数据类型是什么?实际上是否有任何图像加载?在将其作为参数传递给其他函数之前,您不会尝试进行验证。 –
frame.type()和temp.type()输出为16.这里[OpenCV](http://docs.opencv.org/2.4/modules/core/doc/operations_on_arrays.html)没有说明应该是什么一个数组类型。 –
