It is set up a calculating model of which simplifies workpiece position error calculating within the machine tool ' s fixture 得出简化工件在机床夹具中的定位误差的计算方法。
Therefore , techniques must be developed to mitigate these impairments and improve the location accuracy 特别是非视距传播效应是导致定位误差的主要原因,必须采用相应的算法来减小它们的影响。
In order to modify the error created by original odometer , the iterative closest point algorithm ( icp ) is adopted in this paper 为了纠正里程计的定位误差,本文采用了迭代近邻点( icp )算法。
Through numerical simulation , the accuracy of the methods has been intensively studied . the contour figures of localization errors are given 通过数值仿真,对算法的定位精度进行了研究,给出了双基地声呐定位误差的几何分布。
And aiming at the errors in time difference measuring , wave velocity measuring and the location mode , the resolvent is proposed 分析了产生声源定位误差的主要因素:时差测量误差、波速测量误差及定位方法引起的误差,并提出了相应的解决办法。
