I want to estimate POSE of circular object in OpenCV and grip it. One thing I can detect is circle center but it is not enough to estimate pose. According to my search; I can use SolvePnp algorithm to estimate pose. But it required atleast 4 points. How can I define another points for circular objects to use this algorithm?
