Hello,
I am relatively new to image processing so please bear with me.
I am planning to use P3P Pose Estimation in a project that would require quite high (~100 Hz) update rate. For that I have been going through some papers which describe the P3P algorithm.
It has been mentioned that P3P gives upto 4 solutions out of which one is used. A fourth point can be used to remove the ambiguity.
What I want to know is that if we have a general idea about the pose of the object and the 3D points which we intend to correspondence are known to be fixed on a rigid object (e.g. a helmet) is is possible to constraint the P3P algorithm so that it gives a unique solution?
Any further explanation of the P3P algorithm would be most welcome.
Many thanks in advance.
