摘要
激光测量过程受到其它影响因素的干扰,存在一定的测量误差,导致激光测量结果不稳定,可靠性低,为了防止其它影响因素对激光测量精度的干扰,提出了基于证据理论的激光测量误差的建模与修正方法。首先分析激光测量误差的产生机理,找到影响激光测量精度的因素,然后通过实验采集激光测量误差数据,并根据激光测量误差进行建模,挖掘激光测量误差的变化规律,最后采用证据理论对激光测量误差进行融合,修正激光测量结果,以提高激光测量精度,实验结果表明,本文方法可以修正其它影响因素对激光测量精度的不利影响,可以更好描述激光测量误差的变化规律,获得了高精度的激光测量结果,实验结果验证了本文方法的有效性。
Laser measurement process will be disturbed by other factors,and there are certain measurement errors,which lead to instability and low reliability of laser measurement results.In order to prevent interference of other factors on laser measurement accuracy,a method of modeling and correcting laser measurement errors based on evidence theory is proposed.Firstly,the mechanism of laser measurement error is analyzed,and the factors affecting the laser measurement accuracy are found.Then,the laser measurement error data are collected through experiments,and the laser measurement error is modeled according to the laser measurement error.Finally,the laser measurement error is fused by evidence theory to correct the laser measurement error.The experimental results show that this method can correct the adverse effects of other factors on the laser measurement accuracy,better describe the variation law of laser measurement errors,and obtain high-precision laser measurement results.The experimental results verify the effectiveness of this method.
