Hmm, not really and can't remember. The second line should be the algebraic form of line -> plane intersection: https://en.wikipedia.org/wiki/Line%E2%80%93plane_intersection The third line is a inverse pinhole projection: https://towardsdatascience.com/inverse-projection-transformation-c866ccedef1c
thank you, and great project
https://github.com/laxnpander/OpenREALM/blob/master/modules/realm_core/src/camera.cpp#L348 cv::Mat u = (cv::Mat_(3, 1) << img_bounds.at(i, 0), img_bounds.at(i, 1), 1.0);
double s = (pt - m_t).dot(n) / (m_R m_K.inv() u).dot(n);
cv::Mat p = m_R (s m_K.inv() * u) + m_t;
here code use algorithm,has any reference paper?
