OpenCV.norm 中的断言错误
Assertion error in OpenCV.norm
我正在借助汉明距离寻找视频中两幅图像的差异。这是我的代码:
#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;
}
问题是在
double dist = norm(frame, temp, NORM_HAMMING);
程序下降到
**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:这段代码有效:
double dist = norm(frame, temp, NORM_L2);
你需要把图片调成灰色
cvtColor(frame, frame, CV_BGR2GRAY);
