# Rotation Matrix from recoverPose is not symmetric

Hello,

i am using the recoverPose() function in OpenCV but i don't get a symmetrical rotation matrix.

But shouldn't it return a symmetrical rotation matrix?
My results are looking like:

```
R = 0.998585723955729, 0.02348487299776981, 0.04769709270061936;
-0.02232705043463718, 0.9994464428542043, -0.02466395517687959,
-0.04824991948907295, 0.02356413814160357, 0.9985572976364158;
t = -0.9982022017535427,
0.005659929033547541,
0.05966849769949602;
```

My both pictures are:

I am not aware about any symmetrical constraint for the rotation matrix but I may be wrong. From my knowledge, one property is that the rotation matrix should be orthogonal:

`det(R)=1`

`norm(first / second / third colum)=1`

Cross-post as there is already a good answer there...
