Head-mounted device, and deformation state identification method and device of head-mounted device

The invention discloses a head-mounted device and a deformation state identification method and device of the head-mounted device, and relates to the technical field of head-mounted devices. The head-mounted device comprises an inertial sensor used for collecting inertial data of the posture head-mounted device; the first distance sensor is used for collecting a first distance between the posture head-mounted equipment and the face of the wearer in a first direction; the second distance sensor is used for collecting a second distance between the posture head-mounted equipment and the face of the wearer in a second direction different from the posture first direction; and the processing unit is used for acquiring a first attitude distance, a second attitude distance and attitude inertial data at each acquisition moment within the adjustment duration, and determining a first deformation state of the head-mounted device according to the first attitude distance, the second attitude distance and the attitude inert
