Embodiment 1

[0076] see figure 1 , figure 1 It is a schematic flowchart of a method for searching questions based on image preprocessing disclosed in an embodiment of the present invention. in, figure 1 The described method for searching questions based on image preprocessing is applicable to learning devices such as tutoring machines, learning machines, and learning tablets, and is not limited by the embodiments of the present invention. Wherein, the operating system of the above-mentioned learning device may include but not limited to Android operating system, IOS operating system, Symbian (Symbian) operating system, Black Berry (Blackberry) operating system, Windows Phone8 operating system, etc., the embodiment of the present invention does not Do limited. Such as figure 1 As shown, the method for searching questions based on image preprocessing may include the following steps:

[0077] 101. The learning device recognizes the color of the specified object in the first image.

Embodiment 2

[0095] see Figure 5 , Figure 5 It is a schematic flowchart of another method for searching questions based on image preprocessing disclosed in the embodiment of the present invention. Such as Figure 5 As shown, the method for searching questions based on image preprocessing includes the following steps:

[0096] 501. The learning device recognizes the color of the designated object in the first image, the first position coordinates of the designated object designated in the first image, and the color of characters in the first image.

[0097] In the embodiment of the present invention, after the location area of ​​the specified object in the first image is identified, the position of a specific part of the specified object in the first image may be further identified. For example, the position of the tip of the finger or the tip of the pen in the first image may be identified, so as to obtain the specified first position coordinates of the fingertip or the tip of the pen i...

Embodiment 3

[0116] see Figure 6 , Figure 6 It is a schematic flowchart of another method for searching questions based on image preprocessing disclosed in the embodiment of the present invention. Such as Figure 6 As shown, the method for searching questions based on image preprocessing includes the following steps:

[0117] 601. When the learning device detects a preset voice wake-up word, control its shooting module to take a mirror image in the reflective device as a first image.

[0118] In the embodiment of the present invention, the reflective device is installed on the learning equipment, and the mirror surface of the reflective device forms a preset angle with the lens surface of the shooting module. Please also refer to Figure 7 , Figure 7 It is an example diagram of the shooting process of a learning device to capture images. Such as Figure 7 As shown, the way the learning device controls the shooting module to take the mirror image in the reflective device as the fi...

Abstract

The invention discloses a question searching method based on image preprocessing and learning equipment. The method comprises the following steps: identifying the color of a specified object in a first image; identifying the color of the character in the first image; adjusting the color of the specified object in the first image to a color opposite to the color of the character to obtain a secondimage; and performing character recognition on the second image to obtain to-be-searched topic content, and searching learning content corresponding to the to-be-searched topic content. By implementing the embodiment of the invention, the accuracy of character recognition in the image can be improved, so that questions possibly required to be searched by a user can be recognized more accurately, the accuracy of question search can be improved, and learning contents more conforming to expectation are fed back to the user.

Description

technical field [0001] The invention relates to the field of education technology, in particular to a method for searching questions based on image preprocessing and a learning device. Background technique [0002] At present, more and more learning devices (such as tutoring machines, learning tablets, etc.) have the function of searching questions. Most learning devices support image search questions: users use learning devices to take pictures of the questions to be searched, and learning devices can identify the corresponding topic content from the captured images, and search for corresponding answers or problem-solving ideas based on the identified topic content Wait for the learning content. [0003] However, in practice, it is found that when there are objects with similar or similar colors to the characters in the captured image, there are many errors in the title content identified from the captured image, which leads to the searched learning content not meeting the...
