In this paper, a method combining PnP and OI algorithms is developed to measure the pose of a humanoid robot in high precision in order to play table tennis. The PnP-based algorithm is employed to obtain the rough pose, which is taken as the initial value of the OI algorithm. The OI algorithm optimizes the result in order to ensure the orthogonal orientation matrix of the pose. Considering the real-time,...
This paper presents a camera calibration method that could be used in humanoid robot vision system. Extended Kalman filter is used to estimate camera parameters. This method can take planer board feature points of the image or the object's 3D axis as inputs when doing known motion, test results show this algorithm can get good results. If the camera parameters are known, the relationship between a...
