The invention belongs to the technical field of mobile augmented reality, and provides a photorealistic sense generation method of a mobile augmented reality type doodle picture book. The photorealistic sense generation method comprises the steps of: (1) texture design, which is used for designing textures displayed by a three-dimensional augmented model before and after pickup; (2) three-dimensional augmented model design, which is used for designing a geometric model of a role model of a doodle object and drawing a UV plot map of the role model; (3) and vertex Shader design, wherein picture book images in an image sequence acquired by a camera are subjected to a series of processing steps such as projection, conversion and rasterization by means of a Shader program, so that the display of the model after pickup is more realistic. The photorealistic sense generation method can expand the material selection range of the doodle picture book, can creatively solve the problem of normal illumination and visual effect of a three-dimensional augmented model provided with a narrow component, and establishes the method for generating photorealistic sense of the mobile augmented reality type doodle picture book.
