Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention.

In general, the stereo geometry is to describe a spatial stereo image in a three-dimensional space using two-dimensional plane images. However, in fact, many users are not strong in spatial imagination, and thus it is difficult to understand the spatial stereo graphic described by the two-dimensional image. Therefore, for the geometric test questions with high difficulty, even though a plurality of tools such as photographing and searching the questions can quickly find the answers of the questions and display the answers to the questions to the user, the user cannot establish the presentation effect of the spatial stereo graph in the mind according to the geometric images described in the two-dimensional plane, so that the user can hardly really understand the entity even if the user obtains the answer analysis.
In view of this, embodiments of the present invention provide a display processing method and apparatus, which draw a spatial stereo graphic in a three-dimensional space based on a geometric image in a two-dimensional plane, so as to achieve a purpose of presenting a stereo geometric image that is difficult to present and analyze on the two-dimensional plane in the three-dimensional space.
Fig. 1 is a schematic operating environment diagram of a display processing method according to an embodiment of the present invention. Referring to fig. 1, an electronic device establishes network connection with a server, and after obtaining a planar graph to be analyzed, the electronic device draws a spatial stereo graph based on the planar graph to be analyzed, and sends a test question corresponding to the planar graph to be analyzed to the server, so that the server retrieves an answer analysis matched with the server, and sends the answer analysis to the electronic device; or the server can also obtain the planar graph to be analyzed, draw the spatial stereo graph based on the planar graph to be analyzed, retrieve the answer analysis matched with the test question corresponding to the planar graph to be analyzed according to the test question, and send the answer analysis to the electronic equipment.
Next, a detailed description will be given of a display processing method according to an embodiment of the present invention, taking the example of generating a spatial stereo image by an electronic device in addition to fig. 1. For example, see fig. 2.
Fig. 2 is a flowchart of a display processing method according to an embodiment of the present invention, which illustrates how to generate a spatial stereo image in detail from the perspective of an electronic device, and the embodiment includes:
101. and acquiring a planar graph to be analyzed, wherein the planar graph to be analyzed is used for describing a spatial stereo graph.
For example, an APP (application) is installed on the electronic device, and the APP may be an APP carried by an operating system of the electronic device or an APP of a third party downloaded by a user. When a user answers the solid geometry test questions, for the test questions which cannot establish the presentation effect of the space solid graph in the mind according to the plane graph presented in the two-dimensional plane, the plane graph to be analyzed is obtained through the APP. For example, the user clicks a shooting button of the APP to input a shooting instruction, the electronic device receives the shooting instruction, and takes a picture of the test question, so that the plane figure to be analyzed is shot. For another example, when a user browses a test question by using an electronic device, for a test question which cannot establish a presentation effect of a spatial three-dimensional graph in the brain according to a geometric image described in a two-dimensional plane, long-press, copy and the like are performed on the test question, so that the geometric image in the test question is stored locally, and a planar graph to be analyzed is obtained. And then, clicking a preview button of the APP by the user, finding the plane graph to be analyzed and uploading the plane graph to be analyzed so as to load the plane graph to be analyzed on the APP.
102. And converting the planar graph to be analyzed into a spatial stereo graph.
After the electronic equipment acquires the planar graph to be analyzed, the planar image to be analyzed is converted into a spatial stereo graph according to the position relation of points, lines, surfaces and the like in the planar graph to be analyzed or in combination with associated characters of test questions and the like.
103. And displaying the spatial stereo graph.
In this step, the electronic device displays a three-dimensional spatial stereo graphic on the screen, so that the user can visually and clearly see the presentation effect of the spatial stereo graphic.
According to the display processing method provided by the embodiment of the invention, after the electronic equipment acquires the planar graph to be analyzed for describing the spatial stereo graph on the two-dimensional plane, the planar graph to be analyzed is converted into the spatial stereo graph and displayed. In the process, the spatial solid figure in the three-dimensional space is drawn based on the geometric image in the two-dimensional plane, so that the purpose of presenting the spatial image which is difficult to present and analyze on the two-dimensional plane in the three-dimensional space is achieved.
Fig. 3 is a flowchart of another display processing method according to an embodiment of the present invention, which is used for explaining how to generate a spatial stereo image in detail from the perspective of an electronic device, and the embodiment includes:
201. and acquiring a planar graph to be analyzed, wherein the planar graph to be analyzed is used for describing a spatial stereo graph.
Specifically, refer to the description of step 101 above, and are not described herein again.
202. And determining the spatial position of each vertex of the spatial three-dimensional graph according to the planar graph to be analyzed.
For example, since the planar graph to be analyzed is substantially an image on a two-dimensional plane for describing the spatial stereo graph, and when the spatial stereo graph is drawn, the spatial position of each vertex of the spatial stereo graph needs to be determined, in this step, the spatial position of each vertex of the corresponding spatial stereo graph needs to be determined according to the planar graph to be analyzed.
203. And determining the connection line relation among different vertexes in each vertex.
For example, when the spatial stereo image is drawn after the vertices of the spatial stereo image are determined, it is necessary to determine the connection line relationship between the vertices and whether the connection line is a broken line or a solid line, and therefore, in this step, it is necessary to identify the connection line relationship between different vertices according to an image recognition technique or the like.
204. And drawing the space three-dimensional graph according to the space position of each vertex and the connection line relation.
Illustratively, after the spatial position of each vertex of the spatial stereo graph, the connection relation of different vertices in each vertex, and the like are determined, the vertices may be connected in a canvas, so as to draw the spatial stereo graph. For example, in the Web page (Web) technology, it is necessary to draw a 3D solid geometry image in a Web page by using an Application Program Interface (API) of a Web graphics library (Web GL) through coordinate information of a set point, connection information, and the like in a canvas. The Web GL is a 3D drawing protocol and comprises Web GL1.0 and Web GL2.0, wherein the Web GL1.0 is based on OpenGL ES 2.0, provides an API of 3D graphics, uses HTML5 canvas (canvas) and allows a document object model interface to be utilized; the Web GL2.0 is based on OpenGL ES3.0, is an extension of the Web GL1.0, introduces a new API, and can realize automatic memory management by using part of JavaScript.
205. And displaying the spatial stereo graph.
206. And identifying the operation of the user on the space three-dimensional graph, and transforming the space three-dimensional graph according to the operation.
The operation comprises moving a vertex of the spatial stereo graph, zooming any one edge of the spatial stereo graph, rotating the spatial stereo graph, and moving the vertex or the edge of the spatial stereo graph. For example, the user presses a vertex and drags, thereby triggering the spatial stereo graphic to deform. Assuming that the spatial stereo image is displayed according to the first geometric rule before the operation, and the spatial stereo image is a cube under the first geometric rule, the user can press and drag the vertex a during the interaction process, so that the cube is transformed into a diamond shape, and the like. Wherein the first geometric rule is used for indicating the relation of different elements constituting the space solid figure, and the elements comprise points, lines or planes.
In addition, in the interaction process, besides that the user operates the spatial solid figure on the screen of the electronic device in a pressing, dragging and other modes to enable the spatial solid figure to generate shape transformation, a user-defined geometric rule, which is hereinafter referred to as a second geometric rule, can be input through the screen of the electronic device. And after receiving a second geometric rule input by the user, the electronic equipment transforms the spatial solid graph according to the second geometric rule, wherein the transformation comprises at least one of zooming, moving and rotating.
For example, the user may input the second geometric rule in the electronic device by handwriting, voice, or the like, so that the electronic device recalculates the coordinates of each vertex of the spatial stereo graphic according to the second geometric rule, thereby performing operations such as enlarging, reducing, rotating, or deforming the spatial stereo graphic. Assuming that before the operation, the spatial solid pattern is displayed according to a first geometric rule, the spatial solid pattern includes two edges perpendicular to each other, which are AB and BC, respectively, and AB is equal to BC under the first geometric rule, then in the interaction process, the user may input a second geometric rule, such as AB is equal to 2BC, so that the spatial solid pattern changes.
The above-described enlargement, reduction, rotation, and the like of the spatial stereo graphic may be triggered by using an API of the web GL. Wherein,
according to the display processing method provided by the embodiment of the invention, after the planar image to be analyzed for describing the spatial stereo image on the two-dimensional plane is obtained, the spatial position of each vertex of the spatial stereo image and the connection relation of different vertices are determined according to the planar image to be analyzed, and then the spatial stereo image is drawn according to the spatial position and the connection relation of each vertex. In the process, the space solid graph in the three-dimensional space is drawn based on the geometric image in the two-dimensional plane, so that the purpose of presenting the space solid graph which is difficult to present and analyze on the two-dimensional plane in the three-dimensional space is achieved.
In general, a solid geometry test question has, in addition to a planar figure to be analyzed on a two-dimensional plane, corresponding associated text describing the spatial solid figure. For example, referring to fig. 4, fig. 4 is a schematic diagram illustrating a planar graph to be analyzed and associated text in a display processing method according to an embodiment of the present invention.
Referring to fig. 4, the planar graph to be analyzed on the two-dimensional plane is a graph for characterizing a cube, and the spatial solid graph is a graph, i.e. 8 vertexes of the cube are A, B, C, D, A1, B1, C1, and D1, respectively, and AB ═ BC, BC ═ CD, CD ═ DA, AD ═ CD. The dotted box represents text.
When drawing the spatial stereo graph, the spatial position and the connection relation of each vertex are considered, and associated characters are also required to be considered. At this time, when the electronic device draws the spatial three-dimensional graph according to the spatial position of each vertex and the connection relation, acquiring associated characters of the planar graph to be analyzed, wherein the associated characters are used for describing the spatial three-dimensional graph, converting the associated characters into texts, and generating a first geometric rule according to the texts, wherein the first geometric rule is used for indicating the relation of different elements forming the spatial three-dimensional graph, and the elements comprise points, lines or planes; and determining the spatial position of each vertex of the spatial solid figure according to the first geometric rule.
For example, when a planar graph to be analyzed is obtained by a photographing mode, after the geometric image and the associated characters are displayed in a viewing frame, photographing is performed, so that an original image containing the geometric image and the associated characters is obtained, the geometric image and the associated characters are respectively extracted from the original image, and an image is separately generated for the geometric image part, so that the image to be analyzed is obtained; for the associated text portion, the associated text is converted into text by Optical Character Recognition (OCR) technology or the like, and then the text is represented as a first geometric rule by using a geometric rule library. And finally, when the space three-dimensional graph is drawn, drawing the space three-dimensional graph based on the first geometric rule, the space position of each vertex and the connection line relation.
Generally, an image for describing a spatial stereo graphic on a two-dimensional plane has two situations, one is that a coordinate system is established on the two-dimensional plane, and at this time, the electronic device determines the spatial position of each vertex of the spatial stereo graphic according to the coordinate system; in another case, no spatial coordinate system is established on the two-dimensional plane, and at this time, the electronic device determines the spatial position of each vertex of the spatial stereo graph according to the image characteristics of the planar graph to be analyzed, such as the relative position of each vertex. Next, how to determine the positions of the respective vertices of the spatial stereo image will be described in detail.
First, a coordinate system is established on a two-dimensional plane.
In this case, when the electronic device determines the spatial position of each vertex of the spatial stereo graphic according to the planar graphic to be analyzed, the electronic device determines the spatial coordinate of each vertex of the spatial stereo graphic according to the spatial coordinate system in the planar graphic to be analyzed, and determines the spatial position of each vertex of the spatial stereo graphic according to the spatial coordinate of each vertex of the spatial stereo graphic.
Illustratively, for a planar graph to be analyzed with a coordinate system, after a user obtains the planar graph to be analyzed by photographing or other methods, the OCR technology is utilized to identify the coordinate position of each vertex in the space, i.e. the spatial position, according to the coordinate information labeled by each vertex in the planar graph to be analyzed. Then, the electronic device restores the spatial stereo graphic described on the two-dimensional plane to the spatial stereo graphic in the three-dimensional space according to the spatial coordinate system and the information of each vertex, the solid line, the dotted line and the like on the two-dimensional plane, and the user can change the presentation effect again through an interactive mode of rotating, zooming in, zooming out, moving each vertex and the like.
In this embodiment, the purpose of restoring a planar graph to be analyzed, which is used for describing a spatial stereo graph on a two-dimensional plane, to a three-dimensional space is achieved.
Secondly, no coordinate system is established on the two-dimensional plane.
In this case, when the electronic device determines the spatial position of each vertex of the spatial three-dimensional graph according to the planar graph to be analyzed, a spatial coordinate system is determined according to the relative position of elements in the planar graph to be analyzed, where the elements include points, lines, or planes; and determining the spatial position of each vertex of the spatial three-dimensional graph according to the spatial coordinate system.
For example, for a planar graph to be analyzed without a coordinate system, after a user obtains the planar graph to be analyzed by photographing or other methods, a spatial coordinate system is identified according to the relative position of each vertex, and then the position space of each vertex is determined based on the spatial coordinate system. For example, a scale is drawn for each coordinate axis in the spatial coordinate system; and determining the distance of each vertex in the vertexes relative to each coordinate axis in the space coordinate system, so as to obtain the space position of the corresponding vertex in the space stereo graph.
When the position space of each vertex is determined based on the space coordinate system, all coordinate axes of the space coordinate system are subjected to scale subdivision in an equidistant mode, the distance between the vertex and the coordinate axes is determined, the scale of the vertex on the coordinate axes can be obtained, and then the scales of the three coordinate axes are combined, and the space position of the vertex can be obtained. For example, the vertex a { x1, y1, z1}, where x1, y1, z1 are the lengths of the unit scale values in the subdivision process with equidistant scales, respectively.
In this embodiment, the purpose of restoring a planar graph to be analyzed, which is used for describing a spatial stereo graph on a two-dimensional plane, to a three-dimensional space is achieved.
In the foregoing embodiment, after determining the connection relationship between different vertices in each vertex, the electronic device identifies, for any two first vertices and second vertices having the connection relationship among the vertices, a type of the connection relationship between the first vertex and the second vertex, where the type includes a solid line connection relationship or a dotted line connection relationship, and then stores the type of the connection relationship between the first vertex and the second vertex.
For example, after determining the connection line relationship between different vertices in the vertices, the electronic device may identify vertices implementing connection and vertices implementing dotted connection according to an image recognition technique, and then store the identified results, such as { a, B, solid line }, { A, C, dotted line }, where A, B, C are the vertices of the spatial solid pattern, respectively, and vertex a and vertex B are connected by a solid line, and vertex a and vertex C are connected by a dotted line.
In the above embodiment, after the spatial stereo graphic is drawn, the spatial stereo graphic may be transformed according to the input of the user. That is, the spatial stereo graphic is an interactive spatial stereo graphic. The interaction process is explained in detail below.
In a feasible implementation manner, after the electronic device draws the spatial solid graph according to the spatial position of each vertex and the connection relation, a second geometric rule input by a user is received, where the second geometric rule is a rule defined by the user, and the spatial solid graph is transformed according to the second geometric rule.
For example, the user may input the second geometric rule in the electronic device by handwriting, voice, or the like, so that the electronic device recalculates the coordinates of each vertex of the spatial stereo graphic according to the second geometric rule, thereby performing operations such as enlarging, reducing, rotating, or deforming the spatial stereo graphic. Continuing with the example in fig. 3, under the first geometric rule, AB is BC, the user may input AB is 2BC, etc. during the interaction process, so that the spatial stereo image changes.
