Fiber-optic gyroscope calibration method based on regular hexahedron and marble platform

The invention discloses a fiber-optic gyroscope calibration method based on a regular hexahedron and a marble platform and relates to a fiber-optic gyroscope calibration method. The method disclosed by the invention aims at solving the problem that in the traditional fiber-optic gyroscope calibration method, the calibration is performed just by the aid of an expensive high-precision three-axis turntable, and the calibration results have large errors. The method comprises the following steps: I, sufficiently preheating fiber-optic gyroscopes, and carrying out real-time acquisition on output signals of fiber-optic gyroscopes and accelerometers on the x, y and z axes; II, respectively obtaining the differences between a forward process output sum of steps (2) and (3) and a reverse process output sum of steps (4) and (5) in the processes of acquiring the output signals of the fiber-optic gyroscopes and the accelerometer on the z axis, acquiring the output signals of the fiber-optic gyroscopes and the acceleromete
