| 2017-04-26 01:38:18 -0600 | commented question | Need explaination about rvecs returned from SolvePnP Don't know whether you got your answer yet, but bear in mind that (1) solvePnP gives you the translation from the camera coordinate frame to the object coordinate frame as tvec, and the rotation from the camera frame to the object frame as rvec , and (2) - which always gets me - that OpenCV specifies the camera coordinate frame as +Z=forward=from camera sensor through lens into the world, +X=right, +Y=down |
| 2017-04-26 01:38:07 -0600 | commented answer | SolvePnp rvec suddenly begins to give opposite/unexpected values , is this observed before? Thanks for the suggestion of http://www.boost.org/doc/libs/1_46_1/libs/math/doc/quaternion/html/ (Boost/Quaternions) - that library is surprisingly rarely referenced. |
