Problems solved by technology

[0003] However, for the former, the method of expert review is accurate and reliable, but the efficiency is not high; for the latter, the review method based on the comparison of lattice approximation, due to the writing style problems of calligraphy, etc. , the accuracy of this method is relatively poor

Embodiment 1

[0125] The following takes the copying scene as an example to describe. The content written by the writer is called "work", that is, the current calligraphy work mentioned above.

[0126] The writing path parameters of each example character are saved in the database in advance. In this embodiment, the writing path parameter only saves the center line of the stroke when the example character is written.

[0127] Repeat the following steps 1.1 to 1.2 for each word in the work:

[0128] 1.1 According to the writing order of the strokes of a single character, extract the stroke passing area, and use the image recognition algorithm to calculate the center line of the stroke as the writing path parameter of the single character.

[0129] 1.2 Compare the writing path parameters of the individual character with the writing path parameters of the corresponding example word in the database, such as Figure 5 As shown, the score of each word is obtained according to the degree of coi...

Embodiment 2

[0133] The following takes the copying scene as an example to describe. The content written by the writer is called "work", that is, the current calligraphy work mentioned above.

[0134] During the original material collection process, the writing path parameters of each example character are saved in the database. The writing path parameters include, for example, the real-time height, tilt angle and writing speed data of the writing pen. Multiple inertial sensors can be installed in the writing pen to obtain the above parameters in real time while writing.

[0135] During the writing process of the writer, the writing process is continuously photographed through the camera device, such as Image 6 As shown, the image recognition algorithm is used to track the outline of the pen in real time to obtain the position of the pen, and calculate the real-time height, tilt angle, and writing speed data of the pen. Alternatively, in order to further improve the accuracy of subsequ...

Embodiment 3

[0141] Take the copying scene as an example to describe.

[0142] The processing similar to that of the preferred embodiment 1 is used to obtain the first type of score for each single-character image in the work.

[0143] A second type of score for each single-character image in the work is obtained using a process similar to that of the preferred embodiment 2.

[0144] Through weighted calculation, the weighted average value (or weighted sum) of the first-type score and the second-type score of each single-character image is obtained as the score of each single-character image. Wherein, the weights of the first type of scoring and the second type of scoring are both 1, for example.

[0145] Through weighted calculation, the weighted average (or weighted sum) of the ratings of all single-character images in the work is obtained as the total score of the work, and the weight of each single-character image is, for example, 1.

[0146] To sum up, in the embodiments according t...

Abstract

The invention provides a calligraphy writing path evaluation device and method and electronic equipment. The calligraphy writing path evaluation device comprises a current path obtaining unit, a reference path determination unit and a work scoring unit, wherein the current path obtaining unit is suitable for obtaining a writing path parameter of the current calligraphy work; the reference path determination unit is suitable for determining a reference work corresponding to the current calligraphy work and a writing path parameter of the reference work; and the work scoring unit is suitable forcalculating a score of the current calligraphy work according to a similarity between the current calligraphy work and the writing path parameter of the corresponding reference work. According to thecalligraphy writing path evaluation device and method and the electronic equipment, both the correctness and efficiency can be considered, and the defects in the prior art can be overcome.

Description

technical field [0001] The present disclosure relates to information processing technology, in particular to a calligraphy writing path evaluation device, method and electronic equipment. Background technique [0002] At present, for the evaluation of the level of calligraphy learners' works, calligraphy experts usually manually review and evaluate their works. In addition, there are still some that use computer automatic review, and the general method is to compare the dot matrix similarity with the standard word. The higher the dot matrix similarity, the higher the score. [0003] However, for the former, the method of expert review is accurate and reliable, but the efficiency is not high; for the latter, the review method based on the comparison of lattice approximation, due to the writing style problems of calligraphy, etc. , but the accuracy of this method is relatively poor. Contents of the invention [0004] A brief summary of the present disclosure is given below...
