Method, device and system for calibrating gyroscope

Abstract

The invention discloses a method, apparatus and system for calibrating a gyroscope, and belongs to the field of measuring instruments. The method comprises the following steps: obtaining the forward rotation speed components and backward rotation speed components of a gyroscope to be calibrated on each coordinate axis by making the gyroscope rotate around three sensitive axes in the forward direction and backward direction; obtaining the forward rotation speed components and backward rotation speed components of a high-precision gyroscope, which moves along with the gyroscope to be calibrated, on each coordinate axis; wherein the precision of the high-precision gyroscope is higher than that of the gyroscope to be calibrated; and finally calibrating the gyroscope to be calibrated according to the forward rotation speed components and backward rotation speed components of the high-precision gyroscope on each coordinate axis. The provided method utilizes a high-precision gyroscope to replace a high-precision rotary table to calibrate a gyroscope to be calibrated, and thus common labs can use the method to calibrate a gyroscope.

Description

Method, device and system for calibrating gyroscope technical field Embodiments of the present invention relate to the field of measuring instruments, and in particular to a method, device and system for calibrating a gyroscope. Background technique In order to measure the posture of a moving object, measuring instruments such as gyroscopes and electronic compass can be used. A gyroscope is a measuring instrument capable of measuring the rotational speed of an object and can be used in many fields. For example, a gyroscope can be used in the navigation field. In the field of navigation, gyroscopes are used to measure the rotational speed of objects required for object navigation. The gyroscope needs to be welded and installed before use. After welding and installed, the relevant characteristics of the gyroscope will change, so the gyroscope needs to be calibrated before use. If an uncalibrated gyroscope is used to measure an object, there may be an error in the output sp...

Problems solved by technology

The precision of the high-precision turntable is high, so the price of the high-precision turntable is very expensive

In addition, the installation of the high-precision turntable is complicated, and the requirements for the installation site are strict, so that the general laboratory cannot have a high-precision turntable, so that it is impossible to calibrate the gyroscope
