Device position correction method and device position correction system

A device position correction system, suitable for a wearable device, the device position correction system comprising:

• a head-mounted display device (HMD), comprising:
• a camera, configured to capture a wearable device image;
• a storage device;
• and
• a processor, configured to access an object detector and a limb detection model stored in the storage device to execute the object detector and the limb detection model;
• wherein the processor executes the following actions:
• detect a wearable device position in the wearable device image using the object detector;
• detect a plurality of skeleton points and a limb position of a limb in the wearable device image using the limb detection model to determine the body part corresponding to the limb;
• and
• generate calibration information related the wearable device position according to the skeleton points and the limb position.
