Coordinate frame transformation from NED to OpenCV convention, and the Pinhole Camera Model

Hello, I'm working on an SFM module where I have camera coordinates wrt a world coordinate system (in NED). I have the calibrated camera intrinsics matrix, and with the R,T of the camera wrt world, I compute the Projection matrix (intrinscs matrix * R|T) for each image, and camera position. However, I'm not sure if this Projection matrix is right since the R|T is in NED, and openCV uses a different convention.I'm trying to use the CV::SFM::triangulatePoints, but I'm not getting consistent results. How will this affect the projection matrix, and is the conversion of the poses to the OpenCV frame necessary?
