用于Matlab的OpenCV(C ++)以双精度保存矩阵 [英] Saving matrix in double precision from OpenCV (C++) for Matlab

问题描述

我想将通过OpenCV创建的矩阵与Matlab中的矩阵进行比较.如果矩阵是uint8，则将它们另存为pgm图像即可解决问题.但是我的矩阵是CV_64FC1(双精度)，不能另存为图像.有什么简单的方法可以保存我的双矩阵以在Matlab中读取?

I want to compare matrices created from OpenCV with the ones in Matlab. If the matrices are uint8, Saving them as pgm images would do the trick. But my matrices are CV_64FC1 (double) that can't be saved as images. Is there any easy way to save my double matrix for reading in Matlab?

推荐答案

从OpenCV示例中尝试一下.

Try this one from OpenCV samples.

Mat r
std::stringstream ss;
ss << format(r,"csv") << endl << endl;
myFile << ss.str();
// or even this
myFile << format(r,"csv") << endl << endl;
