文摘In this paper, we take the model of Laser range finder based on synchronized scanner as example, show how to use data fusion method in the process of sensor model designing to get more robust output. Also we provide our idea on the relation of sensor model, data fusion and system structure, and in the paper, there is a solution that transform the parameter space to get linear model for Kalman filter.
文摘为准确测量超薄壁回转件旋压后的外径尺寸,提出了一种基于重构横截面轮廓曲线的等效外径在机测量方法。该方法利用周向均布的3套线激光位移传感器与旋轮架的轴向移动模块,获得回转件任意轴向位置横截面的外轮廓数据;通过对3套传感器所获截面数据的坐标变换及数据匹配,实现截面完整轮廓数据的精确拼接,并以离散数据点的保形曲线重构方法重构截面外轮廓曲线,利用同一闭合曲线各变形状态的长度不变性,得到了截面等效外径;分别以芯轴及薄壁回转件开展了外径检测实验。实验结果表明:所提方法可准确测量超薄壁回转件外径,其精度为0.019 mm.
