Method and device for obtaining blackboard-writing information medium and electronic equipment

Abstract

The invention provides a method and device for obtaining blackboard-writing information, a medium and electronic equipment. The method comprises the steps of in a writing area of a writing board, acquiring second track information in a second line area from the back of a first line area; analyzing second track information to acquire an evaluation interval length threshold; sequentially analyzingthe second track information according to the evaluation interval length threshold value to obtain information of a plurality of unit areas; sequentially extracting unit track information from each piece of unit region information; and calling a trajectory analysis model to perform character analysis on each piece of unit trajectory information, and obtaining corresponding character coding information in sequence. The unit track information is extracted from the blackboard writing and converted into the character code information, so that the process of converting the blackboard writing information into the character code information is completed, standard character information is provided for students, the reading difficulty brought to the students by blackboard writing difference is reduced, the handwriting recording time is shortened, and the lesson listening efficiency is improved.

Description

technical field [0001] The present disclosure relates to the field of computer technology, and in particular, to a method, apparatus, medium and electronic device for acquiring information on blackboard writing. Background technique [0002] The traditional blackboard is a flat surface that can be written repeatedly. The board surface is hard and it is a writing tool that can be repeatedly erased. Typically used for teaching, conference discussions, or personal and family notes. [0003] With the rapid development of online education, in online teaching, the electronic whiteboard replaces the blackboard in the original classroom, and the demonstration on the electronic whiteboard by teachers and students is as convenient as the original presentation on the blackboard in the classroom, and its application is more and more extensive. [0004] However, the content displayed on the electronic whiteboard is to reproduce the content of the teacher's original writing on the blackb...

Problems solved by technology

[0004] However, the display content of the electronic whiteboard is to reproduce the content of the teacher's original blackboard writing

Because each teacher's writing on the blackboard is very different, it often brings great difficulties to students in class reading, thus affecting the efficiency of students' listening to lectures
