Inclination angle sensor calibration method based on one-dimensional rotary mounting table calibration device

Abstract

The invention discloses an inclination angle sensor calibration method based on a one-dimensional rotary mounting table calibration device, and relates to the field of sensor calibration. The methodcomprises the steps of 1 preparing before inclination angle sensor calibration; 2 randomly selecting a plurality of groups of test points on a rotary mounting table, randomly selecting one test pointin each group, deflecting the rotary mounting table by 180 degrees through a special control software system to obtain the other test point, and obtaining the measurement value of the inclination angle sensor of each group of test points; 4 processing data and calculating calibration parameters; according to the data analysis model established in the step 3, carrying out linear fitting on the multiple groups of test data by adopting a least square method to acquire a linearity error coefficient k and a temperature offset coefficient b, and substituting the linearity error coefficient k and thetemperature offset coefficient b into the relational expression of the true value and the measured value in the third step to acquire a calibration mathematical model and complete calibration work. The method has the advantages of being high in precision, high in operability and high in efficiency.
