A photorealistic generation method for mobile augmented reality graffiti picture books

Abstract

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.

Description

technical field [0001] The invention belongs to the technical field of mobile augmented reality, and more specifically relates to a method for generating a sense of reality of a mobile enhanced doodle picture book. Background technique [0002] Augmented Reality (AR) technology can realize the seamless connection between the real world and the virtual world. With the improvement of the computing power of mobile terminals and the integrated use of various sensing modules, the combination of AR technology and mobile technology has realized AR Miniaturization and portability can meet people's needs for interactivity, immediacy, and personalization. [0003] Print publications are a classic learning resource. Through AR technology, it can be endowed with more digital content, and the new interactive experience can attract readers more effectively. At present, a series of AR products related to print publishing have emerged, such as educational cards, picture books and teaching ...

Problems solved by technology

However, this type of picture book also has the following defects: (1) Due to the limitation of UV display, AR recognition maps usually require avoiding the selection of narrow and long objects, and mostly use stick figures to draw objects, which limits the selection of publications ;(2) The black boundary line of the recognition map is often mapped to the model, resulting in black edges or black spots on the model after coloring, resulting in bad visual effects; (3) Replace the preset model texture with the recognition map, If there is no special treatment, the realism of the lighting effect is insufficient, and a special shader (Shader) needs to be designed to improve the display effect of the AR model
