Problems solved by technology

Compared with the way of reading e-books, it is inconvenient to find keywords when reading paper books
For example, when looking at the table of contents of an unfamiliar reference book, if you need to find the subsection where a certain knowledge point is located, you need to search the table of contents one by one, which is very inefficient

Embodiment 1

[0075] image 3 It is a flowchart of a method for keyword retrieval of paper books by using a mobile phone according to Embodiment 1 of the present invention. Such as image 3 Shown, a kind of method utilizing mobile phone to carry out paper book keyword retrieval described in the present invention, comprises:

[0076] S1. Enter keywords in the search mode, and obtain the current page picture of the paper book through the camera;

[0077] S2. Perform image-to-text conversion on the acquired image on the current page and record the pixels where each text is located, perform keyword retrieval based on the converted text paragraphs, and mark the pixels corresponding to the retrieved keywords.

[0078] The technical solution of the present invention uses the mobile phone to take real-time pictures of the pages where the current paper book is located, and inquires the position of the keywords in real time according to the pictures taken, and marks them on the screen of the mobile...

Embodiment 2

[0080] Figure 4 It is a flowchart of a method for keyword retrieval of paper books by using a mobile phone according to Embodiment 2 of the present invention. Such as Figure 4 As shown, in this embodiment, the step S1, input keywords in the search mode, and obtain the picture of the current page of the paper book through the camera, specifically:

[0081] S100. In the retrieval mode, the user inputs a keyword, points the camera at the current page of the paper book, and the mobile phone continuously takes pictures of the current page of the paper book;

[0082] It should be noted that the continuous shooting adopted by the present invention is a mode of camera shooting, most of the photos in the publications are taken in the continuous shooting mode, such as geological photographers, they take a picture in the continuous shooting mode A lot of photos, and then choose the most satisfactory few. Using continuous shooting facilitates selection of the best, highest-resolution...

Abstract

The invention discloses a method and a device for carrying out paper book keyword retrieval by a mobile phone, and belongs to the technical field of communication. The method for carrying out the paper book keyword retrieval by the mobile phone comprises the following steps: S1) under a retrieval mode, inputting a keyword, and obtaining a current page picture of a paper book through a camera; and S2) carrying out picture-character conversion on the current page picture, recording a pixel where each character is positioned, carrying out the keyword retrieval on the basis of a character paragraph formed after the conversion, and labeling the pixel corresponding to the retrieved keyword. In the technical scheme, the mobile phone is used to shoot the page where the paper book is positioned at present in real time, the position of the keyword is inquired in real time according to the shot frame and the position is labeled on the screen of the mobile phone, so that a user can quickly find the position of the keyword according to the labeled position on the screen.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method and device for searching paper book keywords by using a mobile phone. Background technique [0002] Although e-books are accepted by more and more people with the popularization of electronic devices, paper books are still in the mainstream. In addition, newspapers, periodicals, documents, etc. are also mainly printed into paper for people to read. Compared with the way of reading e-books, it is inconvenient to find keywords when reading paper books. For example, when looking at the table of contents of an unfamiliar reference book, if you need to find the subsection where a certain knowledge point is located, you need to search the table of contents one by one, which is very inefficient. To search for keywords in e-books, you only need to directly input the keywords in the search mode, and the position of the keywords can be found automatically and quickly. [...
