Embodiment 1

[0087] see figure 1 , figure 1 It is a schematic flowchart of a topic segmentation method disclosed in an embodiment of the present invention. like figure 1 As shown, the topic segmentation method includes the following steps:

[0088] 110. Acquire the target page picture, and detect the question number information and text line information in the target page picture.

[0089] The target page image includes one or more layouts, and each layout includes one or more questions. The image of the target page can be obtained by taking photos of carriers such as workbooks, exercise books, and test papers through an image acquisition device such as a camera. The image acquisition device can be integrated into smart devices, such as placing the carrier on a point reader or a tutor In the front, the carrier is photographed through the front camera of the smart device, or the image acquisition device is a discrete device capable of communicating with the smart device. The target pag...

Abstract

The embodiment of the invention discloses a question segmentation method and device based on topic numbers and text lines, equipment and a medium. The method comprises the steps of obtaining a targetpage picture, and detecting question number information and text line information in the target page picture; determining boundary coordinate information of the text lines, and clustering to obtain categories; taking the minimum value of the boundary coordinates in the category as the boundary value of the layout, and carrying out layout segmentation on the target page picture to obtain the layout; determining leading rows and non-leading rows of the layout, and determining the leading row associated with each non-leading row according to the position relationship between the leading rows andthe non-leading rows so as to construct questions by the leading rows and the non-leading rows; and calculating boundary information of the questions according to the text line information of the leading lines and the non-leading lines in the questions, and segmenting each question. According to the method of the invention, by combining the question number and the text line information, the structural relationship of the questions is fully mined, the problem that the adjacent questions are easy to confuse is solved, and the question segmentation accuracy is improved.

Description

technical field [0001] The present invention relates to the technical field of intelligent equipment, in particular to a method, device, electronic equipment and storage medium for segmenting a topic based on a topic number and a text line. Background technique [0002] The current method for the topic segmentation method in the image is usually to train an end-to-end topic segmentation model, and divide different topics according to the topic range. However, in some cases, the distribution of questions is more complex, and adjacent questions often have no clear boundaries, and the model sometimes cannot distinguish between two adjacent questions, so there are cases where multiple adjacent questions cannot be separated. In addition, because the pictures to be recognized are uploaded by users, there are blurring, tilting, wrinkles and occlusions in the test paper, which reduces the accuracy of question segmentation to a certain extent. Contents of the invention [0003] In...
