大直径测量系统的特征层数据融合

Feature level fusion of large diameter measurement system

为了克服多滚轮大直径测量系统中单一传感器的局限性,利用多传感器数据融合技术,充分挖掘不同时间和空间的测量数据信息,极大地提高了测量系统的性能和效率。将自适应加权算法应用于大直径测量系统的特征层数据融合,减少了不确定误差的影响。仿真结果表明:该算法得到的测量结果更加精确,效果较好。

In multiple rolling wheels large diameter measurement system,multi-sensor data fusion can avoid the localization of single sensor,and it takes full advantage of measurement data information of difficult space-time so that the system's performance and efficiency can be improved greatly.The method of adaptive weight and mean is used in large diameter measurement system in this paper,and precision measurement result is gained.
