Rotary table calibration method and device, electronic equipment and storage medium

Abstract

The embodiment of the invention provides a turntable calibration method, which comprises the following steps: global temperature calibration is carried out on chips to be calibrated on a turntable to obtain temperature compensation curves corresponding to the chips to be calibrated, each chip to be calibrated corresponds to one temperature compensation curve, and the global temperature calibration is carried out under all temperature conditions; local temperature calibration is carried out on a to-be-calibrated product on a rotary table, the local fixed deviation of the to-be-calibrated product is obtained, the local temperature calibration is carried out under preset temperature conditions, and the number of the preset temperature conditions is smaller than the number of all the temperature conditions. The corresponding chip to be calibrated is installed in the product to be calibrated; and on the basis of the temperature compensation curve and the local fixed deviation, each product to be calibrated is calibrated, and a calibration result of each product to be calibrated is obtained.

Description

technical field [0001] The invention relates to the technical field of turntable calibration, in particular to a turntable calibration method, device, electronic equipment and storage medium. Background technique [0002] Turntable equipment is an auxiliary equipment that helps inertial measurement device-related products to eliminate the fixed deviation that comes with the device when it comes out. Inertial measurement devices are affected by device characteristics and often have certain fixed deviations. When producing corresponding products, calibration is often required. The calibration process needs to calibrate the characteristic curve of the inertial measurement device at different temperatures. The traditional solution is to place the entire product equipped with the inertial measurement device in the turntable equipment, and perform inherent deviation calibration of the entire equipment. Due to the difference in the model and appearance of the product, the product ...

AI Technical Summary

Problems solved by technology

[0003] The embodiment of the present invention provides a turntable calibration method, which aims to solve the problem that the temperature difference range of heating and cooling in the calibration process is large, and the time required for heating and cooling is too long, resulting in a slow calibration process for inertial measurement devices, so that the calibration of inertial measurement devices The efficiency is low. During the calibration process, the entire product needs to be powered for power supply, which increases the energy consumption of production and increases the cost of production.
