Synthesis method for dynamic three-dimensional pictures

The invention relates to a synthesis method for dynamic three-dimensional pictures, which has the beneficial effects that the synthesis method is based on the principle of vision persistence, so a user can observe a dynamic effect without wearing glasses, when the displacement between a grating and a picture changes, human eyes can see the originally static picture moving, so that a horizontal-longitudinal-stretching dynamic effect can be achieved, the user can represent the to-be-expressed contents through a dynamic form according to different design concepts to completely catch the eye of an observer, the cost is very low, the technical application range is wide, and the method can be used for advertising, so that the advertisement representing form is more novel and more irresistible, thereby being capable of attracting the attention of customers; and a grating sheet for observing the dynamic effect is designed by picture processing software, the number of grating lines and the proportion of black and white stripes can be set according to the condition of an original manuscript, a platemaking method adopts the traditional film process, the manufacturing process is simple, the cost is very low, and the technology has a very good market prospect, and can create out various novel products according to the innovative thinking of the user, so that the application range is widened, and an enterprise has a promising future.
