Problems solved by technology

This way of using images as identification and matching carriers, on the one hand, needs to pre-enter and store a large amount of image data for matching on the server side, the storage cost is high, and the pre-image entry preparation work is cumbersome; on the other hand, because only Preset images can be recognized and produce augmented reality effects, and mobile augmented realization terminals can only function in very limited specific image scenarios, which greatly restricts the wide application of augmented reality technology

Embodiment

[0038] Such as figure 1 As shown, a mobile augmented reality reading method based on text recognition mainly includes the following six steps:

[0039] S1. The mobile device acquires a captured image P containing text.

[0040] S2. The mobile device preprocesses the image P obtained in step S1 to obtain an image P', and then uploads it to the server.

[0041] S3. The server performs character detection and recognition on the received image P', and obtains a character set {W i} and the position information {Loc i}. where W i Indicates the i-th text detected, Loc i Indicates the position where the text appears in the image P'.

[0042] S4. According to the predefined keyword dictionary, the server performs keyword matching in the text in the image P' obtained in step S3, and obtains the keyword set {T j}, and where each keyword appears in the image P'{Pos j}. where T j Indicates the jth keyword detected, Pos j Indicates that the keyword T j appears at the position in...

Abstract

The invention discloses a character recognition based mobile augmented reality reading method.The method includes steps: 1, a mobile device acquires a shot original image containing characters; 2, the mobile device preprocesses the acquired original image and uploads to a server; 3, the server acquires a character set and position information of each character in the image; 4, the server acquires a keyword set and position information of each keyword; 5, the server searches multimedia resources related to each keyword and returns corresponding results to the mobile device; 6, aiming at each group of received results, the mobile terminal precisely overlays the multimedia resources onto the original image.The invention further discloses a reading system for implementation of the character recognition based mobile augmented reality reading method.The reading system comprises a mobile phone terminal and a server terminal, and the mobile phone terminal and the server terminal are in communication through the internet.The character recognition based mobile augmented reality reading method and the reading system have the advantages of low storage cost of the server and the like.

Description

technical field [0001] The invention relates to an augmented reality system technology, in particular to a text recognition-based mobile augmented reality reading method and a reading system thereof. Background technique [0002] In the previous mode of reading books and newspapers, the information people get only comes from the books and newspapers they read, and the amount of information they get is small and limited. Enter keywords in the search engine on the PC or mobile terminal to search. This mode is cumbersome to operate, and the interaction between the reader and the newspaper is poor. [0003] In view of the problems existing in the above-mentioned reading mode, the present invention proposes an Augmented Reality (AR) technology combined with text recognition and knowledge base matching technology to accurately superimpose relevant text, images, and videos on the text content read by readers, Help readers get more information conveniently and quickly in the proce...
