Embodiment Construction
[0023] Below, the present invention will be further described in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of not conflicting, the various embodiments described below or the technical features can be combined arbitrarily to form new embodiments. .
[0024] A method for converting physical handwriting to electronic handwriting, such as figure 1 shown, including the following steps:
[0025] Obtain valid cells, obtain the resistance value of each display cell on the physical screen, if the resistance value of the display cell is within the preset range, it means that there are obvious physical handwriting, and it is determined to be a valid cell. It should be understood that the physical screen here is a blackboard in the background art, on which several display cells are arranged. In this embodiment, the resistance value ranges from 0 to 10 ohms, and the preset range is greater than or equal to 6...

The invention provides a method for converting physical handwriting into electronic handwriting, which comprises the following steps of: obtaining the resistance value of each display cell of a physical screen, and if the resistance value of the display cell is within a preset range, judging the display cell as an effective cell; judging the product of the total number of the longitudinal cells and the total number of the transverse cells of the effective cells and the resolution of the whole screen, and converting the electronic coordinates of the corresponding resistance value range into theeffective handwriting according to the judgment result; and drawing the converted electronic coordinates to obtain the electronic handwriting. The invention relates to electronic equipment and a storage medium. The handwriting on the blackboard is converted into the electronic handwriting and stored in a synchronous physical handwriting mode, the thickness of the handwriting can be obtained, theeffectiveness of the handwriting can be judged, and when the physical handwriting is converted into the electronic handwriting, handwriting positioning can be accurately carried out, so that the converted electronic handwriting can restore the physical handwriting to a large extent. Students can focus on warming classroom content after class, and learning efficiency is improved.
Description
technical field [0001] The invention relates to the technical field of teaching aids, in particular to a method for converting physical handwriting to electronic handwriting, electronic equipment, and a storage medium. Background technique [0002] For a long time, using chalk to teach courses in the form of blackboard has always occupied a very important position in the field of education. It not only has the advantage of low teaching cost, but also the teacher's vivid speech and the graphic illustration or explanation on the blackboard can make students' Concentration is greatly improved. However, the blackboards currently on the market cannot convert physical handwriting into electronic handwriting, and cannot save the content written by the teacher on the blackboard, so that students can review the classroom content after class and improve learning efficiency. Contents of the invention [0003] In order to overcome the deficiencies in the prior art, the object of the ...
