What are the differences between posest&#39;s pe::PoseEstimator2d  and  pe::PoseEstimator3d? Which one should be used for a monocular camera? I believe PoseEstimator2d  is based on the SFM method (Structure from Motion). For some reason, I get results only with stereo images and PoseEstimator3d. Does any one have any example of posest for a monocular camera?<br>
