Hello again, The position reported by the current code doesn't make any sense (even wtr to the marker center). As I said I checked it using a physical metric reference. I fixed the code proposed by Wang based on the following response: https://math.stackexchange.com/questions/82602/how-to-find-camera-position-and-rotation-from-a-4x4-matrix So básically: C = -R_t * T Where C: camera pose , R_t is the transpose of the rotation matrix and T is the translation vector. And I started getting correct values....

So I'm not sure if your algorithm is not correct or the implementation has some BUG. But definitely...

Hello All, First of all, thanks for sharing this amazing library. I'm finding it very useful for my research. I think both versions of code are buggy. The code proposed by Wang is almos correct (the rotation matrix should be transposed in before multiplying by the translation vector). I'm posting the correct code ((please, notice the .t() call when calculating the camera position) so please, can you integrate it in the stable version ? I tested the code with a camera and a metric reference and made...
