An Efficient Implicit QR Code System

Abstract

The invention relates to an efficient implicit two-dimensional code system. According to the system, resources are grouped, so that batched download of the resources can be realized, and therefore, resource access efficiency can be improved. At first, at a network side, an administrator extracts the features of each background image, and stores the features and resources corresponding to the background images together in a feature database; a plurality of related background images form one group; when a user side performs photographing, a corresponding mobile terminal application program extracts features from of a photographed image, and automatically accesses the feature database, and downloads all resources corresponding to the background images which belong to the same group as the background image in the database to a mobile terminal; and if the user photographs other background images or real objects which belongs to the group later, the user can directly access the downloaded resources. The resources are grouped, so that the batched download of the resources can be realized, and therefore, frequent communication with a server can be avoided, and the resource access efficiency can be improved.

Description

technical field [0001] The invention relates to the field of mobile terminal resource access, and is an implicit two-dimensional code system that realizes batch downloading of resources by grouping resources to improve resource access efficiency. Background technique [0002] With the continuous development of information technology, it is more and more convenient for people to obtain information through the network. [0003] The traditional resource access method requires the visitor to first input the network address of the resource into the address bar of the browser, and then click the resource link provided by the web page to access more resources. This access method requires the visitor to remember the network address of the resource, which has high requirements for the visitor. [0004] In recent years, with the rapid development of smart mobile terminals, some more convenient resource access methods have emerged. Among them, the most representative and the most wid...

[0005] But the two-dimensional code also has some disadvantages: (1) The appearance of the two-dimensional code is a black and white frame, which lacks aesthetic feeling, and its existence destroys the overall integrity of its environment

For example, in a beautifully printed advertisement, if a QR code is placed somewhere, the beauty of the entire advertisement will be reduced.

(2) In order to improve the recognition rate, the placement of the QR code is subject to certain restrictions. For example, it is usually not used for outdoor billboards, otherwise it will be difficult for users to successfully scan with smart mobile terminals due to the long distance or excessive angle. to get resources

After the existing implicit two-dimensional code system takes pictures of the table and the chair, it needs to access the network and the database twice to obtain the information of the chair and the table respectively, which will reduce the resource access efficiency
