How does a crane lift tens of thousands of tons of boulders? How does the digger dig hard earth and rock? What kind of car can carry a huge bridge deck? Fire machinery, sanitation machinery, mining machinery, how do these engineering vehicles change our lives? Children, especially young boys, are always full of curiosity about these large engineering vehicles of construction machinery, but most parents cannot give their children an accurate and comprehensive answer to many questions about the principles and detailed knowledge of these engineering vehicles. Therefore, How to popularize science to children is very necessary. In the past, most of the popular science books that children read were ordinary paper-based picture albums, which were relatively simple in form and could not meet the needs of today's society, and could not stimulate children's interest in reading to a greater extent. With the development of the times, three-dimensional picture albums have appeared. Compared with traditional picture albums, they have added some interest and enhanced children's hands-on ability. Now there are many AR interactive picture books, using virtual reality technology to make engineering vehicles not on paper alone. Vivid 3D images can interact with children and stimulate children's interest in reading. AR technology is based on the combination of virtual and reality technology on the flat content, resulting in the effect of interactive images. Interactive publications with interactive picture books as the entrance and APP client as the information carrier integrate picture book content and AR technology, which can retain the original readers' basic cognitive reading mode for traditional picture books and use multimedia means such as animation, video and music to assist in expression. Music effects, special effects and other elements are added to the production content of interactive picture books. By touching and clicking on the content of APP corresponding to the picture books, the somatosensory reading area is expanded and the entertainment and interest of reading are enriched. AR technology can be used to realize augmented reality by identifying virtual objects appearing in real body photos. The control of virtual objects by real objects is a novel and interesting technology, which can stimulate users' interest in reading interactive picture books and improve the appreciation value of culture.
