2015-07-11 00:49:20 -0600 | answered a question | undistortPoints, findEssentialMat, recoverPose: What is the relation between their arguments? As it turns out, my data seemingly is off. By using manually labelled correspondences I determined that Possibility 1 and 2 are indeed the correct ones, as one would expect. |

I mean it makes sense in the right image, but in the left image, the lines should converge to the right, as the second frame's camera center is further to the right. |

2015-07-10 03:37:50 -0600 | commented question | opencv 3 essentialmatrix and recoverpose One question is whether the 8 correspondences you have are actually noise-free. In theory, only 5 are required (which should not be coplanar or close to it), but in reality, you need much more because the measurements are imprecise. |
2015-07-10 03:35:42 -0600 | answered a question | openCV 3.0 recoverPose wrong results Well, my impression so far is that translation is computed rather well, but rotation is almost always bullshit, unless there is none between the two frames. But rotation around the z axis like in your case seems to work occasionally. I'm not sure about the equations, but you can use the I'm not sure though if x, y, z is really the order of axes here. Also, you need to pay attention to whether feature coordinates are normalised or not, and possibly try various combination of input parameters when performing undistortion and then finding E (I've outlined the issue here), so something like this may be requires depending on your specific case. |
