The embodiment of the invention provides a predicted feature and an actual feature. A method for tracking an object comprises: obtaining a three-dimensional structural feature and a plane image feature of an object from a video image; generating a three-dimensional space model of the object according to the three-dimensional structural feature; on the basis of the plane image feature and the constructed three-dimensional structural feature, generating an enhanced three-dimensional model of the object; and carrying out object tracking based on the generated enhanced three-dimensional model.
