Embodiment 1

[0043] Such as figure 1 As shown, the present embodiment provides a method for taking pictures and searching for questions, including:

[0044] S101. Taking a picture of the topic to obtain a picture.

[0045] Specifically, the camera lens is aimed at the center of the question to take a picture, and a picture of the test question is obtained for searching the question.

[0046] S102. Calculate the angle between the question placement plane and the camera lens plane.

[0047] In this embodiment, the questions are generally on the test book or textbook, and the test book or textbook is placed on the horizontal desktop. The camera is provided with a gravity sensor, which can calculate the angle between the camera plane and the horizontal plane. When taking pictures of the subject, the angle between the subject plane and the camera plane can be calculated.

[0048] S103. Confirm that the angle is greater than or equal to a preset threshold, and perform deflection correction on...

Embodiment 2

[0054] On the basis of the first embodiment, this embodiment adds specific steps for searching questions.

[0055] Such as figure 2 As shown, a method for searching questions by taking pictures is provided, including:

[0056] S210, taking a picture of the question to obtain a picture.

[0057] Specifically, the camera lens is aimed at the center of the question to take a picture, and a picture of the test question is obtained for searching the question.

[0058] S220. Calculate the angle between the question placement plane and the camera lens plane.

[0059] In this embodiment, the questions are generally on the test book or textbook, and the test book or textbook is placed on the horizontal desktop. The camera is provided with a gravity sensor, which can calculate the angle between the camera plane and the horizontal plane. When taking pictures of the subject, the angle between the subject plane and the camera plane can be calculated.

[0060] S230. Confirm that the an...

Embodiment 3

[0076] This embodiment corresponds to the first embodiment, and please refer to the first embodiment for details that are not exhaustive.

[0077] Such as image 3 As shown, this embodiment provides a system for searching questions by taking pictures, including:

[0078] The camera module 310 is used to take pictures of the questions to obtain pictures.

[0079] The angle calculation module 320 is used to calculate the angle between the subject placement plane and the camera lens plane.

[0080] The correction module 330 is configured to confirm that the angle is greater than or equal to a preset threshold, and perform deflection correction on the picture.

[0081] The question search module 340 is used for searching questions by using the deflection-corrected pictures.

[0082] In this embodiment, the above modules work together to take pictures of the subject, and check whether the photographing angle is reasonable by calculating the angle between the subject placement pl...

Abstract

The invention discloses a title photographing and searching method and system. The method comprises the following steps: photographing a title to obtain a picture; calculating the angle between the title placing plane and the camera lens plane; determining that the angle is greater than or equal to the preset threshold value, and conducting deflection correction on the picture; conducting title searching by utilizing the picture subjected to deflection correction. When the title is photographed, whether the photographing angle is reasonable or not is detected by calculation of the angle between the title placing plane and the camera lens plane, when the angle is greater than the preset threshold value, deflection correction is conducted on the picture, and the picture subjected to deflection correction is utilized to conduct title searching, so that the picture recognition efficiency can be improved, and the title searching accuracy can also be improved.

Description

technical field [0001] The invention relates to the field of intelligent question search, in particular to a method and system for searching questions by taking photos. Background technique [0002] At present, there are many question-searching software on the market. The process of taking pictures and searching questions is relatively simple. You just use the camera to take pictures, and then use the photos to search questions. If the angle of the photo is taken is large, the question information in the photo is not easy. If it is recognized, the accuracy of the search question is not high. Contents of the invention [0003] The purpose of the present invention is to provide a method and system for searching questions by taking pictures. The purpose of the present invention is to solve the problems that the pictures are not easy to be recognized and the accuracy of searching questions is not high due to poor photographing angles. [0004] For reaching this purpose, the p...
