背景技术Background technique
在规范汉字书写教学的整个过程中，小学低年级的汉字教学是基础所在，但低年级的小朋友们书写出的汉字风格多变，需要老师或者家长对每个学生写过的所有汉字都给出纠正信息并辅助改正很难实现。通常，课堂上要么是老师在黑板上，利用粉笔写出一个汉字，然后让学生记住书写时的笔画顺序，或者是让学生照着专门的笔画顺序练字本进行书写。In the entire process of standardizing the teaching of Chinese character writing, the teaching of Chinese characters in the lower grades of primary schools is the foundation. However, the styles of Chinese characters written by children in the lower grades are variable, and teachers or parents need to provide information on all the Chinese characters written by each student. Correcting information and assisting in correction is difficult to achieve. Usually, in class, either the teacher uses chalk to write a Chinese character on the blackboard, and then asks the students to remember the order of strokes when writing, or the students are asked to practice writing according to the special stroke order in a calligraphy book.
相关技术中，在传统汉字书写教学过程中，老师无法一一查看学生书写过程，很难保证学生能够完全正确书写。同时大部分家长和教师没有受过严格的、系统的规范汉字书写教育，即使最终能实现一对一的辅导，教师和家长也无法对学生书写的汉字给出具体化和规范化的评价信息。In related technologies, during the traditional Chinese character writing teaching process, the teacher cannot check the students' writing process one by one, and it is difficult to ensure that the students can write completely correctly. At the same time, most parents and teachers have not received strict and systematic education in standardized Chinese character writing. Even if one-on-one tutoring is eventually achieved, teachers and parents will not be able to provide specific and standardized evaluation information for students' written Chinese characters.

Obviously, the described embodiments are some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present invention.
相关技术中，在传统汉字书写教学过程中，老师无法一一查看学生书写过程，很难保证学生能够完全正确书写。同时大部分家长和教师没有受过严格的、系统的规范汉字书写教育，即使最终能实现一对一的辅导，教师和家长也无法对学生书写的汉字给出具体化和规范化的评价信息。In related technologies, during the traditional Chinese character writing teaching process, the teacher cannot check the students' writing process one by one, and it is difficult to ensure that the students can write completely correctly. At the same time, most parents and teachers have not received strict and systematic education in standardized Chinese character writing. Even if one-on-one tutoring is eventually achieved, teachers and parents will not be able to provide specific and standardized evaluation information for students' written Chinese characters.
为解决上述问题，本发明实施例中提供一种书法测评方法，用于计算机设备中，需要说明的是，其执行主体可以是书法测评装置，该装置可以通过软件、硬件或者软硬件结合的方式实现成为计算机设备的部分或者全部，其中，该计算机设备可以是终端或客户端或服务器，服务器可以是一台服务器，也可以为由多台服务器组成的服务器集群，本申请实施例中的终端可以是智能手机、个人电脑、平板电脑、可穿戴设备以及智能机器人等其他智能硬件设备。下述方法实施例中，均以执行主体是计算机设备为例来进行说明。In order to solve the above problems, embodiments of the present invention provide a calligraphy evaluation method for use in computer equipment. It should be noted that its execution subject can be a calligraphy evaluation device, and the device can be implemented through software, hardware, or a combination of software and hardware. Implemented as part or all of a computer device, where the computer device may be a terminal or a client or a server. The server may be a server or a server cluster composed of multiple servers. The terminal in the embodiment of the present application may They are smartphones, personal computers, tablets, wearable devices, and other smart hardware devices such as smart robots. In the following method embodiments, the execution subject is a computer device as an example for description.
本实施例中的计算机设备，适用于规范汉字书写教学的使用场景。通过本发明提供的书法测评方法，通过收集学生的书写轨迹，将学生的书写轨迹在系统里绘制，采用标准字作为比较对象，对学生的书写进行全方位地评估，并给出具体化和规范化的评价信息，可以更为直观地反映学生的书写错误及错误所在，进一步方便了家长及老师的规范汉字书写教学。The computer equipment in this embodiment is suitable for use scenarios that standardize Chinese character writing teaching. Through the calligraphy evaluation method provided by the present invention, students' writing trajectories are collected, the students' writing trajectories are drawn in the system, and standard words are used as comparison objects to comprehensively evaluate the students' writing and provide concrete and standardized The evaluation information can more intuitively reflect students' writing errors and where they lie, further making it easier for parents and teachers to standardize Chinese character writing teaching.
图1是根据一示例性实施例提出的一种书法测评方法的流程图。如图1所示，书法测评方法包括如下步骤S101至步骤S105。Figure 1 is a flow chart of a calligraphy evaluation method proposed according to an exemplary embodiment. As shown in Figure 1, the calligraphy evaluation method includes the following steps S101 to S105.
在步骤S101中，获取待测书写轨迹。In step S101, the writing trajectory to be measured is obtained.
在本发明实施例中，待测书写轨迹由学生书写，通过将待测书写轨迹上传至计算机，对学生的书写轨迹进行下一步的评估，省去了家长和老师的实时关注。In the embodiment of the present invention, the writing trajectory to be tested is written by the student. By uploading the writing trajectory to be tested to the computer, the student's writing trajectory is evaluated in the next step, eliminating the real-time attention of parents and teachers.
在一示例中，由于现有汉字书写教学系统都是通过类似于书写平板之类设备搭配电容笔来进行汉字数据采集，这些书写板大多较为坚硬且表面光滑，影响书写体验，且在电子屏上书写时很难得到真正纸笔的书写体验。为提供更好的书写体验，学生的书写过程可以通过装有图像采集摄像头的书写数码笔，在已经铺好码点的打印字帖上进行文字书写。通过数码笔前端的高速摄像头实时捕捉笔尖的书写轨迹，同时压力传感器将压力数据传回数据处理器，最终将信息通过蓝牙AP或者USB线对外传输，将待测书写轨迹传回位于计算机设备的书写测评系统。通过点阵纸笔方案可实时采集书写轨迹、笔画、笔顺、书写空间姿态等多维数据，为系统提供支撑；使用点阵笔书写，可以收集书写中的问题，形成基于单字的问题库，使学生在开始练字前，就知道自己问题所在，进而针对解决。In one example, existing Chinese character writing teaching systems collect Chinese character data by using devices such as writing tablets with capacitive pens. Most of these writing tablets are relatively hard and have smooth surfaces, which affects the writing experience and is difficult to detect on electronic screens. It’s hard to get the writing experience of a real pen and paper when writing. In order to provide a better writing experience, students can use a writing digital pen equipped with an image capture camera to write on printed copybooks that have been laid out with code points. The high-speed camera on the front of the digital pen captures the writing trajectory of the pen tip in real time. At the same time, the pressure sensor transmits the pressure data back to the data processor. Finally, the information is transmitted externally through a Bluetooth AP or USB cable, and the writing trajectory to be measured is transmitted back to the writing device located on the computer device. Assessment system. Through the dot matrix pen and paper solution, multi-dimensional data such as writing trajectories, strokes, stroke order, and writing space gestures can be collected in real time to provide support for the system; using dot matrix pen writing, problems in writing can be collected to form a question bank based on single characters, so that students can Before you start practicing calligraphy, you should know where your problems lie and then solve them accordingly.
在步骤S102中，基于待测书写轨迹，绘制得到待测轨迹字图。In step S102, based on the writing trajectory to be measured, a character map of the trajectory to be measured is drawn.
在本发明实施例中，在接收到待测书写轨迹后，为便于对待测书写轨迹进行评估，则将待测书写轨迹输入书法测评系统，以便明确待测书写轨迹的具体评估结果。其中，绘制得到待测轨迹字图的过程可以包括：基于待测书写轨迹，确定当前时刻的笔尖位置信息及书写力度；基于笔尖位置信息，还原得到轨迹位置；基于轨迹位置，计算得到书写速度；基于书写力度及书写速度，绘制得到待测轨迹字图。In the embodiment of the present invention, after receiving the writing trajectory to be measured, in order to facilitate the evaluation of the writing trajectory to be measured, the writing trajectory to be measured is input into the calligraphy evaluation system, so as to clarify the specific evaluation results of the writing trajectory to be measured. Among them, the process of drawing the character map of the trajectory to be tested may include: based on the writing trajectory to be measured, determining the pen tip position information and writing strength at the current moment; based on the pen tip position information, restoring the trajectory position; based on the trajectory position, calculating the writing speed; Based on the writing strength and writing speed, a graph of the trajectory characters to be tested is drawn.
在一示例中，可以在接收到传输回来的待测书写轨迹后，根据文字轨迹时间开始和结束戳进行轨迹绘图还原文字。其中，轨迹绘图包括轨迹位置还原及轨迹粗细还原，包括：In one example, after receiving the transmitted writing trace to be tested, the text can be restored by drawing the trace according to the text trace time start and end stamps. Among them, trajectory drawing includes trajectory position restoration and trajectory thickness restoration, including:
(1)轨迹位置还原：获取点阵笔某一时刻t的笔尖的位置信息Pt，由点阵笔位置传感器提供此刻笔尖位置对应的坐标点。(1) Trajectory position restoration: Obtain the position information Pt of the pen tip of the dot matrix pen at a certain time t, and the dot matrix pen position sensor provides the coordinate point corresponding to the pen tip position at this moment.
(2)轨迹粗细还原：书写轨迹粗细与书写的压力Ft以及书写速度Vt相关，点阵笔某一时刻t的压力大小Ft，由点阵笔压力传感器提供；点阵笔的书写速度Vt可以如下公式计算：(2) Trace thickness restoration: The thickness of the writing trace is related to the writing pressure Ft and the writing speed Vt . The pressure Ft of the dot matrix pen at a certain time t is provided by the dot matrix pen pressure sensor; the writing speed of the dot matrix pen Vt can be calculated as follows:
其中，Pt为t时刻笔尖的位置，Pt-1为t-1时刻笔尖的位置，Vt为书写速度。Among them, Pt is the position of the pen tip at time t, Pt-1 is the position of the pen tip at time t-1, and Vt is the writing speed.
由于书写的力度越大，书写的速度越慢，对应的书写轨迹就越粗，因此书写轨迹粗细可表示为：Since the greater the intensity of writing and the slower the writing speed, the corresponding writing track will be thicker. Therefore, the thickness of the writing track can be expressed as:
其中，Ft为t时刻的压力，It为t时刻的书写轨迹粗细，经实验α＝0.358742时还原书写轨迹的效果最好。根据轨迹位置还原和轨迹粗细还原方法，即可还原较为真实的书写文字。Among them, Ft is the pressure at time t, and It is the thickness of the writing track at time t. According to experiments, the effect of restoring the writing track is best when α = 0.358742. According to the trajectory position restoration and trajectory thickness restoration methods, more realistic written text can be restored.
在步骤S103中，对待测轨迹字图进行文字识别，确定待测书写文字及待测书写文字对应的标准书写文字。In step S103, character recognition is performed on the trace character image to be tested, and the written characters to be tested and the standard written characters corresponding to the written characters to be tested are determined.
在本发明实施例中，为便于明确学生书写的待测轨迹字图是否正确，则需要确定待测轨迹字图对应的标准字，用标准字进行对比，以便明确待测书写是否标准，以及是否存在不标准之处。确定标准字的过程具体包括：对待测轨迹字图进行二值化，得到待测二值化图；基于待测二值化图，识别得到待测书写文字；基于待测书写文字，确定待测书写文字对应的标准书写文字。In the embodiment of the present invention, in order to make it clear whether the student's written trace character diagram to be tested is correct, it is necessary to determine the standard characters corresponding to the trace character diagram to be tested, and compare it with the standard characters, so as to clarify whether the writing to be tested is standard, and whether There are non-standards.
