I have opencv and opencv-contrib cloned with versions 3. You can add more xml according to your requirement. Rodrigues function from OpenCV can convert rvec to R or R to rvec. I was using the tvec and rvec to project image points back into the "real world," but the way I was doing it would simply find a point that's somewhere along the ray that originates from the camera origin. 5) interfaces. Finally, the rvec and tvec parameters are the output pose of the Charuco Board. To improve this, I'm updating my application to use >> homography_to_pose, which is suspect should be more stable (as it takes the >> homography matrix directly as an input).

Nowadays, augmented reality is one of the top research topic in computer vision and robotics fields. The main reason of failing is that there are not enough corners for pose estimation or they are in the same line. Many people try to achieve this and there are a ton of papers covering it, including a recent overview of almost all known methods. The pose estimation is formulated as a DNN-based regression problem towards body joints. Head pose estimation using DLib library. Determine the relative camera pose given two RGB camera frames in openCV-python I would like to determine the relative camera pose given two RGB camera frames. Theoretically, if I know the 3D position of features in the world and their respective 2D position in the image, it should be easy to recover the position of the camera, because there are a rotation matrix and translation vector that define this transformation. As an engineer, he participated in CV and DL projects such as iris recognition, object detection, semantic segmentation, 6-DOF pose estimation, and digital hologram reconstruction.
