摘要
本文介绍了一种应用最优化方法确定测斜仪传感器(加速度传感器,磁通门)的安装误差校正系数的方法。在测斜仪器刻度阶段,需进行传感器线性刻度、轴不正交校正和不同轴校正,涉及到的刻度系数共有21个。可以将该问题转化为标准的非线性最小二乘问题,采用Gauss-Newton法获取迭代计算公式,通过编制计算机软件求取最优化刻度系数。从计算结果来看,这种方法确实有限地减小了测量误差。
In this paper a method to demarcate the calibration coefficient of the sensor of dipmeter by optimization is introduced. During the calibration, there are 21 calibration factors need to calibrate, involved sensor linear scale, non-orthogonal calibration and non-coaxial calibration. It can be transformed into a least squares problem. Gauss-Newton method can be used to acquire the optimization factors through computer software which programmed from iterative formula. According to calculation results, this method is limited to reduce the measurement error.
