The invention provides a posture determination method and equipment and relates to the field of wearable equipment. The posture determination method comprises the following steps: acquiring first reference blood flow information at a reference part of a user; acquiring first target blood flow information at a target part of the user; determining first time difference between a first reference point in the first reference blood flow information and a first target point corresponding to the first reference point in the first target blood flow information; and determining a first posture of the target part according to the first time difference at least. The method and equipment for determining posture of a corresponding part of a body of the user based on blood flow information are provided, and under the condition that some wearable equipment is provided with a sensor used for detecting the blood flow information self, identification on the posture of the body of the user can be realized without increasing hardware cost.
