| 摘 要： | 对并联机构进行标定是实现并联机构几何量校正和高精度定位的前提和基础.目前,现有的自标定方法因得不到完整的并联机构动平台位置和姿态信息,不能满足对并联机构所有几何量进行辨识和标定的要求.针对上述问题,以四自由度并联跟踪台为研究对象,提出了一种新的单目视觉自标定方法,通过实验对其标定精度进行了初步验证,并给出提高标定精度的可行性建议.该方法为并联机床、并联机器人、并联跟踪系统等实现高精度提供了一种新的解决途径.

| Abstract: | 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-... |
