摘要：
The calibration for the parallel mechanism is the premise and base to realize the geometric sense correcting and high accuracy position of the parallel mechanism. As the present self-calibration methods cannot get all information about position and attitude of the motional platform, they can't realize the identification and calibration of all the parallel mechanism geometric parameter. Due to the problems above, a new self-calibration method based on monocular vision was proposed, which took four-degree-of-freedom parallel tracking platform as the subject investigated. The calibration precision was verified preliminarily through the experiments, and some feasibility advices of increasing calibration precision were given. This method provides a new way to realize high accuracy calibration for parallel machines, parallel robots and parallel tracking systems.
