The present invention relates to a method for fabricating children's 3D picture book. After double viewpoint photographing of a model and sequent convergent angle regulation, red-and-blue double color pictures are fabricated and printed. In photographing, a distance between axes is equal to an average value of children's pupil distances, which is 53 mm according to statistics. Then, a distance between focal planes is calculated according to lens parameters and the final printing size. Post composition is achieved by cutting away a left image of a left viewpoint picture and a right image of a right viewpoint picture with a software such as PS, in which the numerical value is the number of pixels in a distance between pixels. A specific numerical value can be calculated according to 3D Stop-Motion Animation V2.0. A red-and-blue double color picture is generated by the way of copying a right image to an R channel.

Since the color having a red value has a "dazzling" phenomenon when using red-and-blue double color glasses to watch the red-and-blue double color picture, the red value in an unnecessary pixel can be removed by the PS software so as to achieve a comfortable three-dimensional effect.
