Provided is a method for training an adaptive rigid prior model. The method includes: initializing model parameters of the adaptive rigid prior model; acquiring a plurality of frames of facial data of a same face by face tracking on training video data using the adaptive rigid prior model; updating the model parameters based on the plurality of frames of facial data; determining whether a condition of stopping updating the model parameters is satisfied; stopping updating the model parameters of the adaptive rigid prior model, and acquiring a final adaptive rigid prior model; and returning to the step of acquiring the plurality of frames of facial data of the same face by face tracking on the training video data using the adaptive rigid prior model.
