Scanning question searching method, intelligent scanning pen and storage medium

Abstract

The invention discloses a scanning question searching method, an intelligent scanning pen and a storage medium. The scanning question searching method comprises the steps of obtaining a scanning picture in a test question scanning process; extracting feature vectors used for describing image features of the scanned picture; and performing retrieval matching in a test question database according to the extracted feature vector, and feeding back a question searching result. According to the method, the feature vectors used for describing the image features of the scanned picture are extracted, retrieval matching is performed in the test question database according to the extracted feature vectors to realize scanning question searching, the feature vectors comprise a plurality of different image features which describe the picture respectively, and the feature vectors are retrieved and matched in the test question database respectively. The question searching result is fed back by integrating the retrieval matching result of each feature vector, so that the scanning picture is subjected to all-directional retrieval from multiple dimensions, and the efficiency and accuracy of question retrieval are improved; in addition, the requirement for the continuity of test question scanning is lowered, and the scanning and question searching experience of the user is improved.

Description

technical field [0001] The invention relates to the technical field of online education, in particular to a method for scanning and searching questions, an intelligent scanning pen and a storage medium. Background technique [0002] Online education, high-quality educational resources can be shared through the Internet platform, which greatly facilitates the use of users and reduces the cost of education. Search questions by taking pictures—a widely used online education method. Users can take pictures of test questions and upload them through smart devices (such as mobile phones), and the cloud server will analyze and extract test questions according to the uploaded test question photos, and retrieve relevant test questions from the test question database. The search results are returned to the user, which can greatly facilitate the user's understanding and mastery of difficult test questions. [0003] Compared with searching for questions by taking photos, the scanning se...

Problems solved by technology

This makes users need to maintain continuity during the operation of scanning test questions, and if there is a situation of missing or rescanning, it will have an impact on the search results of the test questions, resulting in a large gap in the search results of the test questions

This is mainly because the existing scanning search questions mainly rely on the OCR processing of the scanned pictures to identify the picture characters, and the test questions are retrieved based on the characters. Therefore, the integrity and accuracy of the scanned pictures have a greater impact on the test question search results.
