Three-axis acceleration correction method and device

The invention provides a three-axis acceleration correction method and device. The method includes the steps that in a first three-axis acceleration sensor and a second three-axis acceleration sensor of an aircraft, the first three-axis acceleration sensor is determined as a three-axis acceleration sensor to be corrected; according to the acceleration of the first three-axis acceleration sensor, the three-axis angular rate of the first three-axis acceleration sensor and the relative positions of the first three-axis acceleration sensor and the second three-axis acceleration sensor, the three-axis acceleration of the first three-axis acceleration sensor is corrected. By means of the three-axis acceleration correction method and device, the problem that accelerations are not consistent due to the fact that the accelerations on the same aircraft are different in source is solved, and accordingly potential safety hazards caused due to the fact that acceleration signals between a display system and a control system are not consistent are avoided.
