Mat中的数据按行保存到yaml中。
#include "opencv2/opencv.hpp" #include <time.h> using namespace cv; int main(int argc, char** argv) { FileStorage fs("test.yml", FileStorage::WRITE); fs << "frameCount" << 5; fs<<"file_name"<<"filename"; time_t rawtime; time(&rawtime); fs << "calibrationDate" << asctime(localtime(&rawtime)); Mat cameraMatrix = (Mat_<double>(3,3) << 1000, 0, 320, 0, 1000, 240, 0, 0, 1); Mat distCoeffs = (Mat_<double>(5,1) << 0.1, 0.01, -0.001, 0, 0); fs << "cameraMatrix" << cameraMatrix << "distCoeffs" << distCoeffs; fs << "features" << "["; for( int i = 0; i < 3; i++ ) { int x = rand() % 640; int y = rand() % 480; uchar lbp = rand() % 256; fs << "{:" << "x" << x << "y" << y << "lbp" << "[:"; for( int j = 0; j < 8; j++ ) fs << ((lbp >> j) & 1); fs << "]" << "}"; } fs << "]"; Mat test_sequence; test_sequence.create(Size(2, 3), CV_8UC1); test_sequence.setTo(0.0); for(int i=0;i<test_sequence.rows;i++){ for(int j=0;j<test_sequence.cols;j++){ test_sequence.at<uchar>(i,j)=i*j; } } fs<<"test_sequence"<<test_sequence; Mat test_seq_row; test_seq_row.create(Size(4,3), CV_8UC1); test_seq_row.setTo(0.0); for(int i=0;i<test_seq_row.rows;i++){ for(int j=0;j<test_seq_row.cols;j++){ test_seq_row.at<uchar>(i,j)=i*j; } } fs<<"test_sequence"<<test_seq_row; fs.release(); return 0; }
