A method and a device for recognizing a stationary state is provided for resolving the issue of low stationary state recognition accuracy in the prior art. The method comprises: an inertial navigation system obtaining first operation data of a first set duration measured by an IMU, determining N first standard deviations of the first operation data, matching the N first standard deviations against a pre-stored database, and determining N second standard deviations respectively identical to the N first standard deviations; determining N pieces of first information respectively corresponding to the second standard deviations in the pre-stored database, multiplying a first probability of each piece of the N pieces of first information by corresponding weight, summing N multiplied values, and determining an obtained summation value to be a second probability that the N first standard deviations indicate a stationary state; and the inertial navigation system determining that a device at which the inertial navigation system is located is in a stationary state in the first set duration if the second probability is greater than or equal to a stationary probability threshold.
