Research on Structural Parameter Optimization of Binocular Vision Measuring System for Parallel Mechanism

The structural parameter optimization is investigated in field of binocular vision measuring system for moving platform pose of parallel mechanism. It is required for the measuring system to keep the moving platform motion range in the effective field of view of binocular vision. Therefore, a mathematic description was made firstly for effective field of view and the motion range of platform was analyzed on the basis of parallel mechanism work space. Then a mathematic model was established for measuring system. To improve the measurement accuracy of moving platform pose, the optimization index for structural parameters was defined on the basis of pose measurement error analysis. Finally, optimized structural parameters of measuring system are given by use of enumeration method
