specific Embodiment 1

[0058] Specific embodiment one: please refer to Figure 1-7 The electronic format conversion method of blackboard writing in mathematics classroom comprises the following steps:

[0059] S1. The writing pen is fixedly connected to the mobile conversion system, and the mobile conversion system is wirelessly connected to the background cloud.

[0060] S2. The movement conversion system records the track signal generated when the writing pen moves, and sets the writing plane. The setting standard of the writing plane is: the writing pen first writes the set "start" character track in a certain plane signal, the plane is the compose plane.

[0061] S3. The background cloud collects the effective trajectory signal fed back by the mobile conversion system, and converts the effective trajectory signal into a trajectory image; wherein, the effective trajectory signal is the trajectory signal generated by the writing pen only on the writing plane; at the same time, the background clou...

specific Embodiment 2

[0083] Embodiment 2: Different from Embodiment 1, the setting of the writing plane needs to use the writing pen to stay at one point continuously for 3-5 seconds on a plane.

specific Embodiment 3

[0084] Specific embodiment three: different from specific embodiment one, the method for judging the trajectory image in the backstage cloud to form a complete sentence is: after writing on the blackboard once, write on the blackboard again after an interval of 5-8s, the content of the previous blackboard writing is a complete sentence, and write on the blackboard again The content of the writing on the blackboard is another complete sentence.

Abstract

The invention discloses a mathematical classroom blackboard-writing electronic format conversion method, and belongs to the field of education. The mathematical classroom blackboard writing electronic format conversion method comprises the following steps: S1, fixedly connecting a writing pen with a mobile conversion system; S2, setting a writing plane; S3, setting a feedback plane; S4, judging whether a complete sentence is formed or not; S5, converting the track image into characters by adopting a frame image recognition method; S6, cutting and classifying the track images which cannot be converted by the frame image recognition method; S7, integrating and concluding after classification, and placing the recognized characters in a virtual square frame according to the size of the original track image; S8, after the feedback plane is filled with the characters, automatically changing pages, wherein the size of the pages is consistent with that of the original plane. According to the electronic format conversion device, the blackboard writing draft in the mathematics class can be converted into the electronic format in an equal proportion and equal position mode, the character part can be operated, and the content of the blackboard writing draft is easier to understand compared with an electronic document converted according to a writing sequence.

Description

technical field [0001] The invention belongs to the field of education, and more specifically relates to a method for converting electronic formats of blackboard writing in mathematics classrooms. Background technique [0002] Blackboard writing is an important part of teaching content in the teaching classroom. Blackboard writing is a form of speech activity in which teachers write words and symbols on the blackboard during class to convey teaching information and teach and educate people. It is also called teaching written language. From a static point of view, it is a general term for the teaching information that teachers use blackboards to present in concise and concise words, symbols, diagrams, etc. in order to help students understand and master knowledge during the teaching process. [0003] Especially in the classroom of mathematics teaching, since solving mathematical problems requires fast and sensitive thinking, the content of the blackboard writing will be updat...
