Embodiment 1

[0048] figure 1 It is a flow chart of a method for searching questions provided by Embodiment 1 of the present invention. This embodiment is applicable to the case of searching questions through terminal equipment. This method can be executed by the device for searching questions provided by the embodiment of the present invention. Realized by means of software and / or hardware, this device can be integrated in any terminal equipment that needs to search for questions, such as a typical smart terminal (such as a smart phone or a tablet computer, etc.), such as figure 1 As shown, the method specifically includes the following steps:

[0049] S110. Obtain the question stem picture of the target question captured by the camera and the grade data input by the user.

[0050] Wherein, the camera is a camera installed on the smart terminal, and when the user starts the search application in the smart terminal and receives a search command, the camera is turned on. For example, it ma...

Embodiment 2

[0071] figure 2 It is a flow chart of a method for searching questions in Embodiment 2 of the present invention. This embodiment is optimized on the basis of the foregoing Embodiment 1, and provides a preferred method for searching questions. Specifically, according to the stem picture of the question and the Grade data, determining the type of the target topic includes: if the title stem picture includes graphic information, and the grade data is smaller than the preset grade data, then determine that the type of the target topic is a graphic type; If the dry picture does not include graphic information, or the grade data is greater than or equal to the preset grade data, then it is determined that the type of the target topic is a text type.

[0072] Correspondingly, the method in this embodiment specifically includes the following steps:

[0073] S210. Obtain the question stem picture of the target question captured by the camera and the grade data input by the user.

Embodiment 3

[0093] image 3 It is a flow chart of a method for searching questions in Embodiment 3 of the present invention. This embodiment is optimized on the basis of the foregoing embodiments and provides an optimal method for searching questions. Specifically, if the type of the target question is a graphic type , then extracting the local features of the title stem picture of the target title includes: if the type of the target title is a graphic type, converting the title stem picture of the target title into a grayscale picture; extracting the grayscale picture local features.

[0094] Correspondingly, the method in this embodiment specifically includes the following steps:

[0095] S310. Obtain the subject picture of the target subject captured by the camera and the grade data input by the user.

[0096] S320. Determine the type of the target question according to the question stem picture and the grade data.

[0097] S330. If the type of the target topic is a graphic type, co...

Abstract

An embodiment of the invention discloses a topic searching method and a device. The method includes steps of acquiring a subject picture of a target subject shot by a camera and grade data input by auser; confirming the type of the target topic according to the subject picture and the grade data; if the type of the target subject is an image type, extracting local characteristics of the subject picture of the target subject; acquiring analysis data matched with the target subject according to the extracting local characteristics of the subject picture. Through the technical scheme of the invention, the problem of low searching success rate by applying regular searching method to solve some subjects with more pictures which can be solved when the topic searching APP is in use can be solved; the success rate of topic searching is improved.

Description

technical field [0001] The embodiments of the present invention relate to the field of question searching, and in particular to a method and device for searching questions. Background technique [0002] At present, smart terminal products have many search apps that solve students' homework problems. Users can take photos of difficult problems and then input the photo content into the search app, so that the search app can search for the corresponding answer to the problem based on the photo content. . [0003] However, when using the search question APP, for some questions with a lot of graphics, the conventional OCR (Optical Character Recognition, Optical Character Recognition) method cannot be used to recognize the questions, which will make the questions of some grades use the conventional search method and the search will be successful. The rate is relatively low. Contents of the invention [0004] Embodiments of the present invention provide a method and device for ...
