Abstract :
Based on the 2-DOF parallel kinematics mechanism, the research and analysis are made on the simplification of monocular imaging model to guarantee real time control of the mechanism. The transformation equations from the world coordinate system to the camera coordinate system and finally to the computer displaying coordinate system are researched. The disturbance analysis is made considering the possible manufacturing and assembly factors in the practical engineering project. According to the theoretical analysis and the numerical simulation result, the suggested installation parameters of the mechanism are proposed for the practical application engineering.
