3D moving image displaying and information hiding method based on linear array

The invention discloses a 3D moving image displaying and information hiding method based on a linear array, comprising the following steps: making all the 3D pixels in a 3D linear array correspond to the pixels of a 2D plane image of a projector; constructing a 3D image to be displayed by drawing a 2D plane image; projecting the 2D plane image to the 3D linear array through a projection device; making a 3D moving image in the 3D linear array change by changing the 2D plane image; and converting the 3D information into multipath 2D plane information, constructing a 3D image capable of carrying the multipath 2D plane information, and hiding the 3D information by taking the 3D moving image as a carrier. According to the invention, the 2D plane image is converted into a 3D image through projection, the 3D image is converted into a moving image and through the 3D linear array, the 3D information is displayed and hidden, and the effect is outstanding.
