Abstract
In order to obtain the long-time drift characteristics of the designed high-linearity MEMS gyroscope under normal temperature, the combination of vision identification method(computer micro vision system) and traditional electrical method is used to test the vibration characteristics of MEMS gyroscope under driving mode at t=0, 25 min, 120 min respectively. The long-time drift characteristics of MEMS gyroscope and the influence factors produced the long-time drift are obtained by comparing the test results of the vision identification method and the traditional electrical method.
