Picture dynamic processing method, device and terminal equipment

The embodiment of the invention discloses a picture dynamic processing method, device and terminal equipment. The picture dynamic processing method comprises the steps of identifying a moving main body in a target picture and a main body type of the moving main body, and determining the initial position information of each pixel point of the moving main body in the target picture; calculating the middle position information of each pixel point of the moving main body in the target picture at each time point according to a selected motion model matched with the main body type and the initial position information of each pixel point of the moving main body; processing the corresponding pixel points of the moving main body according to each middle position information to obtain a picture frame at each time point, and generating an animation image according to the picture frame at each time point. By adopting the picture dynamic processing method, device and terminal equipment, a dynamic display effect can be quickly realized in one picture, the user operation is simple, and the production is simple and convenient.
