| 摘 要： | 本文提出一种可测量非对称凸轮和对称凸轮中心线位置的最小方差法。证明了方差函数在测量区间内是严格凸函数,从而可用一维搜索法对最小方差值寻优,提高了测量效率。

| Abstract: | This paper is intended to present the minimum varicance method that can be used to detect the position of unsymmetrical or symmetrical cam centerline. It is proved that the variance function in the measurement interval is a strictly convex function. To raise measurement efficiency,the authors use the one-dimensional searching method to hunt the minimum value of the variance function. |
