thank you for your reply,
using ortoghonalized matrix the transformation works fine. Is The wolphram alpha function avaiable online?

Thanks for reply, I use the camera angles orientation (omega, phi ,kappa) to calculate the rotation matrix using the equations as : Cattura.PNG So i think that each vector (= 3 first columns) mathematically is equal to 1, and they should all be orthogonal to each other (X.Y = X.Z = Y.Z = 0). Am i wr...

Thank you Dianel for your quick reply! Actually, the point cloud coordinates are corrected with the global shift option, so I don't think that "option 2" is the problem. Instead, option 1 may have sense. So, according to your suggestion the x y z axes of the camera are not perfectly orthog...

Good morning everyone! I'm new in Cloud Compare and I have a simple doubt regarding the apply transformation tool. I have a point cloud (axes x,y,z, origin o) that I need to transform according to camera axes orientation (let's say x',y',z', camera center c to be used as origin). To do this I've cal...
