A smart conference is an office product that integrates multiple devices such as an electronic whiteboard, a computer, and a remote conference terminal, and has multiple functions such as an interactive smart whiteboard. At present, with the popularization of intelligent conferences, large-size (generally more than 50 inches) intelligent interactive display devices with touch handwriting functions have emerged as the times require. Currently, the writing software for large-scale intelligent interactive display devices on the market can only support basic functions related to writing, such as trajectory writing, handwriting switching, etc., and cannot meet more needs of users.

The terminal system is mainly used to receive user touch instructions, stylus instructions, voice instructions, etc., and display content. This embodiment can automatically calculate the to-be-recognized formula input by the user based on the processing capability of the Android system device itself, with higher response efficiency and lower cost.

需要说明的是，本实施例中的电子白板并非是传统的利用记号笔或者粉笔书写的电子白板，而是指具有触控手写功能的大尺寸(一般为50寸以上)智能交互显示设备；在该智能交互显示设备上，安装有电子白板等书写程序，用户可以利用手指、主动笔或被动笔等在该显示设备上进行书写，该智能交互显示设备可以包含液晶显示器(Liquid Crystal Display，LCD)、有机发光半导体(Organic Electroluminescence Display，OLED)、电子墨水等显示模组，可以实时显示书写笔迹。It should be noted that the electronic whiteboard in this embodiment is not a traditional electronic whiteboard for writing with a marker pen or chalk, but a large-size (generally more than 50 inches) intelligent interactive display device with a touch handwriting function; The intelligent interactive display device is equipped with writing programs such as an electronic whiteboard, and users can use fingers, active pens or passive pens to write on the display device. The intelligent interactive display device may include a liquid crystal display (Liquid Crystal Display, LCD) , organic light-emitting semiconductor (Organic Electroluminescence Display, OLED), electronic ink and other display modules, which can display handwriting in real time.

如图1所示，本实施例提供的一种智能计算方法的实施流程如下所示：As shown in Figure 1, the implementation process of an intelligent computing method provided in this embodiment is as follows:

步骤100、接收用户输入的待识别算式，确定所述待识别算式对应的标准算式； Step 100, receiving the to-be-recognized formula input by the user, and determining the standard formula corresponding to the to-be-recognized formula;

本实施例中的标准算式包括数字、运算符号、字母等字符，本实施例中的标准算式是基于用户输入的待识别算式进行识别得到的，其中识别待识别算式的过程可以是通过服务器执行的，也可以是通过显示设备(如智能交互平板)自身执行的。The standard formula in this embodiment includes characters such as numbers, operation symbols, and letters. The standard formula in this embodiment is obtained by identifying the formula to be recognized based on the user input, and the process of identifying the formula to be recognized can be performed by the server. , and may also be executed by the display device (such as an intelligent interactive tablet) itself.

在一些实施例中，本实施例中用户输入的待识别算式包括但不限于用户手写输入的待识别算式，如用户作用于显示屏上的触摸指令形成的轨迹数据，用户语音输入的待识别算式，如用户通过电子白板的语音采集器输入的语音数据。In some embodiments, the to-be-recognized formula input by the user in this embodiment includes but not limited to the to-be-recognized formula input by the user's handwriting, such as the trajectory data formed by the user's touch instruction on the display screen, and the to-be-recognized formula input by the user's voice. , such as voice data input by the user through the voice collector of the electronic whiteboard.

在一些实施例中，终端***接收并解析用户的触摸指令，将触摸指令上传到白板软件中，白板软件接收触摸指令，形成轨迹数据，在显示屏上显示用户手写的轨迹数据。In some embodiments, the terminal system receives and analyzes the user's touch instruction, uploads the touch instruction to the whiteboard software, and the whiteboard software receives the touch instruction, forms trajectory data, and displays the user's handwritten trajectory data on the display screen.

在一些实施例中，本实施例提供如下任一或任多种确定所述待识别算式对应的标准算式的方式：In some embodiments, this embodiment provides any one or more ways of determining the standard formula corresponding to the formula to be recognized as follows:

方式1)将用户输入的待识别算式发送给服务器，接收所述服务器发送的对所述待识别算式进行识别得到的标准算式；Mode 1) sending the to-be-recognized formula input by the user to the server, and receiving the standard formula obtained by identifying the to-be-recognized formula sent by the server;

实施中，服务器接收到用户输入的待识别算式后，会对所述待识别算式进行识别，将识别得到的标准算式发送给智能交互平板如电子白板。In implementation, after receiving the unrecognized formula input by the user, the server will identify the unrecognized formula, and send the recognized standard formula to an intelligent interactive tablet such as an electronic whiteboard.

在一些实施例中，对待识别算式进行识别的方式基于用户输入的数据类型的不同而不同，具体实施中，如下所示：In some embodiments, the way to identify the formula to be identified is different based on the type of data input by the user. In specific implementation, it is as follows:

1a)接收用户手写输入的待识别算式，对所述待识别算式进行轨迹识别，得到对应的标准算式。1a) Receive the unrecognized formula input by the user's handwriting, perform trajectory recognition on the unrecognized formula, and obtain the corresponding standard formula.

如果用户手写输入的待识别算式是触摸指令形成的轨迹数据，则对轨迹数据进行轨迹识别，确定轨迹数据对应的标准算式，可选的，本实施例中的轨迹识别的算法包括但不限于自动分格算法、联机手写识别算法(Bi-LSTM)中的至少一种。其中，自动分格算法用于按照轨迹点的坐标，将算式拆分成一个一个规律排列的小格子，联机手写识别算法用于将每个小格子里面的轨迹数据进行识别。If the formula to be recognized by the user's handwriting input is the trajectory data formed by the touch command, then perform trajectory recognition on the trajectory data to determine the standard formula corresponding to the trajectory data. Optionally, the algorithm for trajectory recognition in this embodiment includes but is not limited to automatic At least one of lattice algorithm and online handwriting recognition algorithm (Bi-LSTM). Among them, the automatic grid division algorithm is used to split the formula into small grids arranged regularly according to the coordinates of the track points, and the online handwriting recognition algorithm is used to recognize the track data in each small grid.

1b)接收用户语音输入的待识别算式，对所述待识别算式进行语音识别，得到对应的标准算式。1b) Receiving the unrecognized formula input by the user's voice, performing speech recognition on the unrecognized formula, and obtaining the corresponding standard formula.

如果用户语音输入的待识别算式是语音数据，则对语音数据进行语音识别，从而将语音数据转换为对应的算式。If the to-be-recognized formula input by the user's voice is voice data, voice recognition is performed on the voice data, so as to convert the voice data into a corresponding formula.

方式2)对用户输入的待识别算式进行识别，得到对应的标准算式。Mode 2) Recognize the unrecognized formula input by the user to obtain the corresponding standard formula.

该方式下，智能交互平板接收到用户输入的待识别算式后，会对用户输入的待识别算式进行识别，从而利用自身的识别能力确定该待识别算式对应的标准算式。In this way, after receiving the unrecognized formula input by the user, the intelligent interactive tablet will recognize the unrecognized formula input by the user, so as to use its own recognition ability to determine the standard formula corresponding to the unrecognized formula.

2a)接收用户手写输入的待识别算式，对所述待识别算式进行轨迹识别，得到对应的标准算式。2a) Receive the unrecognized formula input by the user's handwriting, perform track recognition on the unrecognized formula, and obtain the corresponding standard formula.

如果用户手写输入的待识别算式是触摸指令形成的轨迹数据，则对轨迹数据进行轨迹识别，确定轨迹数据对应的标准算式；If the formula to be recognized input by the user is the trajectory data formed by the touch command, the trajectory recognition is performed on the trajectory data, and the standard formula corresponding to the trajectory data is determined;

2b)接收用户语音输入的待识别算式，对所述待识别算式进行语音识别，得到对应的标准算式。2b) Receiving the to-be-recognized formula input by the user's voice, performing speech recognition on the to-be-recognized formula, and obtaining the corresponding standard formula.

如果用户输入的待识别算式是语音数据，则对语音数据进行语音识别，从而将语音数据转换为对应的标准算式。If the formula to be recognized input by the user is voice data, perform voice recognition on the voice data, so as to convert the voice data into a corresponding standard formula.

在一些实施例中，如果用户手写输入待识别算式，则还可以提供书写辅助线，从而辅助用户在该辅助线对应的位置书写，从而提高轨迹识别的准确率，还可以控制书写的排版，提高用户的使用体验。需要说明的是，由于目前对用户书写的轨迹信息进行识别时，通常都是通过自动分格算法、联机手写识别算法等，该算法需要按照轨迹点的坐标将用户书写的待识别算式划分成规律排列的小格子，如果没有辅助线用于提示用户下一个字符的书写位置，那么由于大尺寸的智能交互平板，用户在书写过程中不能保证书写的待识别算式都基本处于同一水平线，导致对用户手写输入的待识别算式进行识别时，对待识别算式中属于同一个字符的轨迹信息无法准确地进行分格，进而无法准确地识别出每个分格中的内容，导致最终无法准确地识别出用户手写输入的待识别算式。In some embodiments, if the user enters the formula to be recognized by handwriting, a writing auxiliary line can also be provided to assist the user to write at the position corresponding to the auxiliary line, thereby improving the accuracy of trajectory recognition, and can also control the typesetting of writing to improve User experience. It should be noted that since the current recognition of the trajectory information written by the user is usually through an automatic grid division algorithm, an online handwriting recognition algorithm, etc., the algorithm needs to divide the recognition formula written by the user into regular patterns according to the coordinates of the trajectory points If there is no auxiliary line to remind the user of the writing position of the next character in the arranged small grid, then due to the large-sized intelligent interactive tablet, the user cannot guarantee that the written formulas to be recognized are basically on the same horizontal line during the writing process, resulting in a lot of confusion for the user. When the handwritten input formula to be recognized is recognized, the trajectory information belonging to the same character in the formula to be recognized cannot be accurately divided into grids, and the content in each grid cannot be accurately recognized, resulting in the inability to accurately identify the user in the end.

步骤101、根据预定义的字符类型，对所述标准算式中的字符进行转换，得到转换算式； Step 101. Convert the characters in the standard formula according to the predefined character type to obtain the conversion formula;

在一些实施例中，本实施例提供基于Android平台的电子白板，并利用WebView内核(WebView内核包括多种类型，通常为WebKit引擎)进行智能计算，通过此设计可以实现用户手写数学算式，自动计算出数学算式的结果，保留用户的原始轨迹，并在显示面板显示计算结果。其中，WebView是Android***的原生控件，主要作用是能够与前端界面(网页)响应交互，相当于一个简易的浏览器。由于使用WebView内核进行算式计算，响应效率高，方案实现成本低。In some embodiments, the present embodiment provides an electronic whiteboard based on the Android platform, and uses the WebView kernel (the WebView kernel includes multiple types, usually a WebKit engine) to perform intelligent calculations. Through this design, users can handwrite mathematical formulas and automatically calculate The results of mathematical calculations are obtained, the original track of the user is retained, and the calculation results are displayed on the display panel. Among them, WebView is a native control of the Android system, and its main function is to be able to respond and interact with the front-end interface (web page), which is equivalent to a simple browser. Since the WebView kernel is used for calculation, the response efficiency is high and the cost of solution implementation is low.

Replaced by Math.sqrt() and ÷ by /.

在一些实施例中，本实施例具体通过如下步骤进行计算：In some embodiments, this embodiment specifically calculates through the following steps:

根据显示网页的控件WebView(网页视图)内核支持的字符类型，对所述标准算式中的字符进行转换，得到转换算式；基于所述WebView内核，对所述转换算式进行计算，得到计算结果。According to the character type supported by the webpage control WebView (web view) kernel, the characters in the standard formula are converted to obtain a conversion formula; based on the WebView kernel, the conversion formula is calculated to obtain a calculation result.

需要说明的是，WebView是安卓内置的高性能、嵌入式的浏览器，在Android平台上是一个特殊的View，可以用来显示网页，是一个用于显示网页的控件，WebView类可以被用来在app中仅显示一张在线的网页，还可以用来开发浏览器。WebView内部实现是采用渲染引擎(WebKit引擎)来展示view的内容，提供网页前进后退、网页放大、缩小、搜索等功能。WebView是一个基于WebKit引擎、展现Web页面的控件，Android的WebView在低版本和高版本采用了不同的WebKit内核版本。目前的WebView内核主要用于处理页面的显示问题，而本公开利用WebView内核自身的处理能力来实现计算器功能，从而提高响应效率，降低实现成本。It should be noted that WebView is a built-in high-performance and embedded browser in Android. It is a special View on the Android platform and can be used to display web pages. It is a control for displaying web pages. The WebView class can be used to Only one online webpage is displayed in the app, and it can also be used to develop a browser. The internal implementation of WebView uses a rendering engine (WebKit engine) to display the content of the view, and provides functions such as web page forward and backward, web page zoom in, zoom out, and search. WebView is a control based on the WebKit engine that displays Web pages. Android's WebView uses different WebKit kernel versions in low and high versions. The current WebView kernel is mainly used to deal with page display issues, and the present disclosure uses the processing capability of the WebView kernel itself to realize the calculator function, thereby improving response efficiency and reducing implementation costs.

如图2所示，本实施例提供了一种WebView的调用关系示意图，具体调用的实施流程如下所示：As shown in FIG. 2 , this embodiment provides a schematic diagram of a calling relationship of WebView, and the implementation process of the specific calling is as follows:

实施中，当对用户输入的待识别算式进行识别后，如果确定用户输入的待识别算式中包含等号“＝”，则可以将该计算结果显示在等号后面固定距离处。例如，可以确定该等号的坐标(x1,y1)，将坐标(x1+c,y1)作为显示位置，在该坐标(x1+c,y1)处显示计算结果。其中c为固定值，本实施例中的坐标都是指显示屏上的坐标。In practice, after the recognition of the formula to be recognized input by the user is performed, if it is determined that the formula to be recognized entered by the user contains an equal sign "=", the calculation result may be displayed at a fixed distance behind the equal sign. For example, the coordinate (x1, y1) of the equal sign may be determined, the coordinate (x1+c, y1) is used as the display position, and the calculation result is displayed at the coordinate (x1+c, y1). Wherein c is a fixed value, and the coordinates in this embodiment all refer to the coordinates on the display screen.

在一些实施例中，如果对用户在同一行中输入的待识别算式进行识别后，得到的标准算式中包含了2个或2个以上的等号，说明用户在同一行中书写了多个待识别算式，为了准确计算每一个待识别算式的计算结果，本实施例可以先对包含多个等号的标准算式进行划分，得到多个子算式，从而利用本实施例中的方法对每一个子算式都确定计算结果并显示。具体实施步骤如下：In some embodiments, if the obtained standard formula contains 2 or more equal signs after identifying the formula to be recognized input by the user in the same line, it means that the user has written multiple waiting formulas in the same line. To identify the formula, in order to accurately calculate the calculation result of each formula to be recognized, this embodiment can first divide the standard formula that contains multiple equal signs to obtain multiple sub-calculations, so that each sub-calculation can be calculated using the method in this embodiment.

需要说明的是，显示的标准算式和用户输入的待识别算式是不同的，用户输入的待识别算式是根据用户的触摸指令生成的轨迹数据，显示的形式是基于用户的轨迹数据确定的，而标准算式是对用户输入的数据进行识别得到的，如果识别正确，那么标准算式便是用户输入的手写待识别算式的标准化形式，如果识别错误，那么标准算式是用户输入的手写待识别算式的错误显示。标准算式显示的形式可以由用户自行定义。It should be noted that the displayed standard formula is different from the unrecognized formula input by the user. The unrecognized formula input by the user is the trajectory data generated according to the user's touch command, and the displayed form is determined based on the user's trajectory data. The standard formula is obtained by identifying the data input by the user. If the recognition is correct, the standard formula is the standardized form of the handwritten formula to be recognized entered by the user. If the recognition is wrong, the standard formula is the error of the handwritten formula to be recognized entered by the user. show. The display form of the standard calculation formula can be defined by the user.

如果在用户书写的过程中，会将用户书写的数据识别后显示在该数据的上方，在得到计算结果后，由于此时不需要再提示用户识别的标准算式是否正确，因此可以删除标准算式。If the data written by the user is recognized and displayed above the data during the writing process of the user, after the calculation result is obtained, there is no need to prompt the user whether the recognized standard formula is correct, so the standard formula can be deleted.

(2)若在标准算式对应的第一显示位置显示所述计算结果，则将所述计算结果在显示屏上进行显示之后删除显示的所述计算结果；(2) If the calculation result is displayed at the first display position corresponding to the standard formula, then delete the displayed calculation result after displaying the calculation result on the display screen;

如果在用户书写的过程中，不仅将识别得到的标准算式进行显示，而且在显示的标准算式的后面还显示计算结果，那么在得到计算结果后，可以删除该标准算式以及计算结果。If the user not only displays the recognized standard formula but also displays the calculation result after the displayed standard formula while the user is writing, then the standard formula and the calculation result can be deleted after the calculation result is obtained.

(3)若在所述显示屏上显示所述辅助线，则将所述计算结果在显示屏上进行显示之后删除显示的所述辅助线。(3) If the auxiliary line is displayed on the display screen, the calculation result is displayed on the display screen and then the displayed auxiliary line is deleted.

如果在用户书写的过程中，已经得到并显示计算结果，不需要用户继续书写，此时可以删除辅助线。If the calculation result has been obtained and displayed during the writing process of the user, and the user does not need to continue writing, the auxiliary line can be deleted at this time.

在一些实施例中，本实施例中的转换算式可计算的范围包括但不限于：加、减、乘、除、开根号、平方、立方、指数、三角函数、log计算中的至少一种。本实施例对此不作过多限定。In some embodiments, the calculable range of the conversion formula in this embodiment includes but is not limited to: at least one of addition, subtraction, multiplication, division, square root, square, cube, exponential, trigonometric functions, and log calculations . This embodiment does not make too many limitations on this.

步骤400、对用户输入的待识别算式进行轨迹识别，确定所述待识别算式对应的标准算式； Step 400, perform trajectory recognition on the unrecognized formula input by the user, and determine the standard formula corresponding to the unrecognized formula;

步骤401、根据所述用户输入的待识别算式中的第1个字符在所述显示屏上的字符位置，确定起始坐标，以所述起始坐标为起点，沿预设方向绘制并显示辅助线。Step 401: Determine the starting coordinates according to the character position on the display screen of the first character in the formula to be recognized input by the user, draw and display the auxiliary character along the preset direction with the starting coordinates as the starting point Wire.

步骤402、根据所述用户输入的待识别算式在所述显示屏上显示的第一位置，确定在所述第一位置的上方，按预设标准字符格式，在所述显示屏上显示标准算式。 Step 402, according to the first position of the to-be-recognized formula input by the user displayed on the display screen, determine that it is above the first position, and display the standard formula on the display screen according to the preset standard character format .

步骤403、若确定标准算式包含等号，则根据预定义的字符类型，对标准算式中的字符进行转换；对转换后的转换算式的合法性进行校验，得到校验后的转换算式；对校验后的转换算式进行计算，确定计算结果。 Step 403, if it is determined that the standard formula contains an equal sign, then convert the characters in the standard formula according to the predefined character type; check the legality of the converted conversion formula to obtain the verified conversion formula; The verified conversion formula is calculated to determine the calculation result.

步骤404、对所述计算结果进行数据格式化，得到数据格式化后的计算结果； Step 404, performing data formatting on the calculation result to obtain the calculation result after data formatting;

记录当前轨迹数据中的X轴的最小值Xmin1的目的，是为了确定辅助线起点的X轴的坐标，以用户书写的首个字符的位置对应的X轴坐标为起点的X轴坐标。The purpose of recording the minimum value Xmin1 of the X-axis in the current trajectory data is to determine the X-axis coordinate of the starting point of the auxiliary line, and the X-axis coordinate corresponding to the position of the first character written by the user is the starting X-axis coordinate.

实施中，如果Xmax2＞Xmax1+预设偏移量，说明此时用户书写的是新轨迹数据和之前的轨迹数据不属于同一个字符，因此可以依据之前的轨迹数据中X轴的最小值和Y轴的最大值确定辅助线的起点。In the implementation, if Xmax2>Xmax1+preset offset, it means that the user is writing the new trajectory data and the previous trajectory data do not belong to the same character at this time, so it can be based on the minimum value of the X axis and the Y axis in the previous trajectory data The maximum value of determines the starting point of the auxiliary line.

步骤504、从Ymax1和Ymax2中确定较大值作为辅助线起点的Y轴坐标，将Xmin1作为辅助线起点的X轴坐标，沿X轴方向绘制并显示辅助线。Step 504: Determine the larger value from Ymax1 and Ymax2 as the Y-axis coordinate of the starting point of the auxiliary line, use Xmin1 as the X-axis coordinate of the starting point of the auxiliary line, draw and display the auxiliary line along the X-axis direction.

需要说明的是，本实施例中的坐标轴的原点位于显示屏的左上角，因此，本实施例中确定的辅助线位于轨迹数据的下方。It should be noted that the origin of the coordinate axes in this embodiment is located at the upper left corner of the display screen, therefore, the auxiliary line determined in this embodiment is located below the trajectory data.

在一些示例中，可以设定固定值C，第二显示位置的X轴坐标值＝Xmax+C；In some examples, a fixed value C can be set, and the X-axis coordinate value of the second display position=Xmax+C;

第二显示位置的Y轴坐标值＝(Ymax+Ymin)/2。The Y-axis coordinate value of the second display position=(Ymax+Ymin)/2.

在一些示例中，还可以根据记录的最大值、最小值以及标准算式中字符的个数确定计算结果的大小。In some examples, the size of the calculation result can also be determined according to the recorded maximum value, minimum value and the number of characters in the standard calculation formula.

在一些示例中，可以根据Xmax、Xmin、Ymax、Ymin以及当前字符的个数，确定计算结果的大小。在一些示例中，计算结果显示的大小也可以是固定的。In some examples, the size of the calculation result can be determined according to Xmax, Xmin, Ymax, Ymin and the number of current characters. In some examples, the displayed size of the calculation result may also be fixed.

例如，计算结果的宽度＝(Xmax-Xmin)/(算式中字符的个数)，计算结果的高度＝Ymax-Ymin，从而根据宽度、高度确定计算结果的大小。For example, the width of the calculation result=(Xmax-Xmin)/(the number of characters in the formula), the height of the calculation result=Ymax-Ymin, so the size of the calculation result is determined according to the width and height.

步骤1005、在显示屏的X轴坐标值、Y轴坐标值的位置上显示计算结果。 Step 1005, displaying the calculation results at the positions of the X-axis coordinate value and the Y-axis coordinate value of the display screen.
