METHOD AND DEVICE FOR INITIALIZING A VISUAL INERTIAL UNIT

A posture recognition method is applied to a mobile terminal, the mobile terminal includes a visual inertial unit (301) and an accompanying unit (302) different from the visual inertial unit, and the accompanying unit is started earlier than the visual inertial unit. The method includes: acquiring (102) by the accompanying unit initialization parameters used by the visual inertial unit for initialization when the mobile terminal is in a stable state; and acquiring (104) by the visual inertial unit the initialization parameters from the accompanying unit when an initialization condition is met, and initializing the visual inertial unit based on the acquired initialization parameters, to output posture data of the mobile terminal based on an initialization result.
