【opencv基础】opencv中cv::Mat和eigen数据之间的转换

前言

opencv矩阵结构为：cv::Mat，或者cv::Mat_等，当需要与eigen的矩阵结构相互转换时主要使用函数：cv::eigen2cv和cv::cv2eigen.

code

Eigen::MatrixXd tmp1(values.rows, values.cols);
cv::cv2eigen(values, tmp1);
Eigen::MatrixXd tmp2(this->weights.rows, this->weights.cols);
cv::cv2eigen(this->weights, tmp2);
Eigen::MatrixXd tmp = tmp1 * tmp2;
cv::Mat out;
cv::eigen2cv(tmp, out);
out.convertTo(out, CV_32FC1); 

include

#include <eigen3/Eigen/Dense>
#include <opencv2/core/eigen.hpp>

参考

1. opencv_Mat_eigen;
