Abstract
The invention relates to an AR book and an index augmented reality system and an index augmented reality method based on the same. The system comprises an AR book, an augmented reality stylus, a terminal, and a display module. The augmented reality stylus is used to read the AR book, parse the OID code of a coding rule carried by an object to obtain feature information, and transmit the feature information to the terminal. The terminal includes a decryption module, a data factory control module, a query module, a playing module, a network data control module, a data downloading module, a network data interface, and a cloud platform. According to the invention, the OID code is adopted, and each OID coded graph is formed by arranging many subtle points which are difficult to see with human eyes in accordance with specific rules and corresponds to a specific set of values. The biggest difference between other optical identification codes and a miniaturized bottom code is that the miniaturized bottom code has the characteristics of secrecy and low visual interference and can be hidden under the color pattern of a printed matter. Therefore, high recognition rate and a fast response mechanism are ensured.
Description
