In order to reduce the influence of nonlinear characteristic and temperature on the measuring
accuracy of inclinometer, the application
of polynomial fitting principle to
compensate the measuring error of inclinometer is studied. According to the
analysis of the experimental data of inclinometer, a polynomial model of the
nonlinear error and the measured value is constructed, and then the relation
between the coefficient of the polynomial model and the temperature is obtained
by fitting, and finally the function of
the measurement error of inclinometer on the measured inclination and
temperature is obtained. The results show that this method is feasible and
effective, which can not only reduce the influence of temperature, but also correct its nonlinear error.
