Now, an implementation process of a map processing method according to an embodiment of the present invention is described with reference to the accompanying drawings, and referring to fig. 5, fig. 5 is a schematic implementation flow diagram of a map processing method according to an embodiment of the present invention, including:
step 501: and acquiring real object information.
Obtaining real object information is the first step to achieve augmented reality, and only if a real world image is input into a computer, synthesized with a virtual scene generated by a computer graphics system, and output to the display assembly, a user can see a final augmented scene image.
Here, as shown in fig. 2 or fig. 4, the real object information may be obtained by the camera, for example, when the digital light field camera shoots a real object, such as a person or a natural scene, the complete light field information may be obtained, so that the user can realize where the user wants to see and where the user can automatically focus when using the AR device; moreover, the acquired light is a light set acquired in a real light field, and when the light is synthesized with a virtual scene, the light cannot be distinguished from reality when being seen from glasses. As shown in fig. 3, the information of the real object can be obtained directly by an optical principle, for example, the display module is set as a light wave device capable of transmitting light, so that the light of the real object directly enters human eyes after being subjected to dimming processing, thereby obtaining the real object.
Step 502: the real object and the position information are analyzed.
The perfect combination of virtual and real objects is realized by merging the virtual objects into the exact position in the real world, so the position of the observer in the real object and the angle of the observer's head, even the direction of movement, need to be detected in real time for tracking, so as to help the system decide which virtual object to display, and reconstruct the coordinate system according to the observer's field of view. The measured position information may be various, for example, a video detection method of recognizing a predefined mark, object or reference point in a video image according to a pattern recognition technique and then calculating a coordinate transformation matrix according to the offset and rotation angle thereof; alternatively, the angle of rotation of the user's head is measured by a gyroscope to determine how to translate the coordinates and content of the virtual scene in the field of view.
Step 503: a virtual scene is generated.
In order to obtain the immersion of the AR device, the display device must be made to display images with a sense of reality, and to perform simulation and display in a virtual scene. And after the positioning mark in the system scene is identified, reconstructing a coordinate transfer matrix from the predefined mark to the mark in the current scene, drawing the virtual object by the system according to the transfer matrix, and rendering to generate the virtual scenery.
In order to enhance the interaction characteristics of the user (customer) and the merchant when generating the virtual scenery, the promotion information such as an electronic coupon or an electronic red packet about the merchant is rendered according to the requirements of the merchant and displayed when the user (customer) arrives at the area.
Step 504: merging videos or direct display.
The graphic system firstly calculates affine transformation from the virtual object coordinates to the camera view plane according to the position information of the camera and the positioning marks in the real object, then draws an image of the virtual object on the view plane according to an affine transformation matrix, and finally directly displays the image through an S-HMD (S-HMD), as shown in FIG. 3 or FIG. 4; or as shown in fig. 2, the video of the real object is merged and displayed on a common display.
In addition, in AR applications, a user can manipulate a virtual object through a marked board in a digital desktop system, which makes the operator feel a sense of real contact by making a sound when detecting that the board is in contact with the virtual object; alternatively, the interaction with a computer generated virtual object is achieved by using gloves provided with reflective markers to manipulate virtual objects, such as chess pieces.
Now, an implementation process of a map processing method according to an embodiment of the present invention is described with reference to the accompanying drawings, and referring to fig. 6, fig. 6 is a schematic implementation flow diagram of another map processing method according to an embodiment of the present invention, including:
step 601: and detecting the position information of the host equipment of the client to obtain a positioning result.
For the acquisition of the positioning result, the following two scenarios are included according to whether the position information is the actual position of the user:
scenario one: the position information is the actual position of the user
In an optional embodiment, the positioning service is invoked to obtain the position information of the host device of the client in the real three-dimensional space, so as to obtain the real-time position of the user in the real world, and obtain the positioning result about the host device or the user.
For example, in real life, when a user uses a conventional intelligent electronic device (such as a mobile phone, a vehicle-mounted positioning system, a tablet computer, an intelligent bracelet, and the like), an AR device, or a VR device to perform positioning or navigation, the client may obtain location information of the user according to the above devices, such as a longitude and a latitude of the user.
Scenario two: the location information being a user-specified location
In another alternative embodiment, the location service is invoked to obtain the location information specified by the user, so as to obtain the location result of the location specified by the user.
For example, when the user uses the map service, a location is designated on the display screen of the host device according to actual requirements, such as a certain market supermarket or a leisure fitness place, so as to obtain a positioning result of the designated location.
Step 602: and the client determines candidate interest points which are matched with the positioning result in the interest points of the map according to the positioning result detected in the map.
In an alternative embodiment, in order to accurately obtain the user's preferences, the user preferences may be calculated according to historical behaviors for the points of interest; and then, selecting the interest points with the distance from the positioning result smaller than a distance threshold value in the map, and selecting the interest points matched with the user preference as candidate interest points according to the types of the selected interest points.
For example, firstly, the client records and counts the behavior habits of the user, and evaluates the behavior habits according to the counted behavior habits to obtain the preference of the user, where the counted behavior habits of the user are: the frequency of purchasing cosmetics, shopping or fitness is relatively high, indicating that the user prefers to purchase cosmetics, shopping or fitness, etc. Secondly, after the user preference is counted, the interest points with the distance from the positioning result smaller than the distance threshold value are selected from the map, wherein for the distance threshold value, a certain fixed value can be adopted in the map, and the interest points can also be adaptively selected according to the densities of the summarized interest points in different areas of the map, for example, the distance threshold value used by the area with high density is smaller than that used by the area with low density, so that enough candidate interest points in the area with low density are ensured. Finally, according to the type of the selected interest points, selecting the interest points which are adapted to the user preference as candidate interest points, for example, the type of the interest points can be restaurants, swimming pools, gymnasiums, shopping malls and the like, the user preference can be preference of gourmet food, preference of swimming, preference of fitness and preference of shopping, and the matching of the type and the preference is as follows: a favorite food matching restaurant, a favorite swimming matching natatorium, a favorite fitness matching gym, and a favorite shopping matching mall supermarket.
Step 603: and the client determines the target interest points meeting timeliness conditions according to the service time of the candidate interest points.
In an optional embodiment, a target area including a positioning result is determined, and the interest points included in the target area are sorted in a descending order of the use time according to the sequence of the last use time; and selecting a preset number of interest points with the previous use time in descending order as target interest points.
For example, after the client obtains the positioning result of the user, the client determines a target area surrounding the positioning result according to the positioning result, and obtains information of a target building in the target area, such as a supermarket, a restaurant, a gymnasium, a natatorium and the like around the user; then, according to the frequency of the user frequently visiting places such as shopping malls, supermarkets, restaurants, gymnasiums, natatoriums and the like recently or the time sequence of last visiting, the places are ranked, for example, the place with the highest frequency of last visiting is ranked in the front, and the place with the lowest frequency is ranked at the last; or the place visited last is arranged in front, the place visited first is arranged in back, and then when the target interest point is determined, a preset number of interest points with the use time in the descending order are selected as the target interest points. In actual development, the sorting described above may be implemented using a Least Recently Used (LRU) algorithm.
Here, the application scenario of the LRU algorithm in the embodiment of the present invention is continuously described, for example, when a browser browses a web page, a downloaded picture is temporarily stored in a local temporary folder, and when the browser accesses the web page again, the downloaded picture is directly read from the local temporary folder. However, the temporary folder for storing pictures has a certain capacity limitation, if too many webpages are browsed, some least frequently used pictures are deleted, and only some most recently used pictures are reserved, so that the LRU algorithm is needed.
In an optional embodiment, in order to quickly find target interest points around a user and improve the calculation rate of the intelligent electronic device, the map is divided into a plurality of candidate areas according to a predetermined size, and an area corresponding to a positioning result is determined as a target area.
For example, the display area is first divided into a plurality of candidate areas according to a certain size, for example, in the displayed map, the displayed map is divided into six areas, such as area a, area B, area C, area D, area E, area F, and the like, as shown in fig. 7A, wherein the candidate areas may be rectangles, circles, ellipses, or the like; and then, after the area division is finished, determining a target area according to the positioning result, and if the positioning result is in the range of the area A, taking the area A as the target area. Here, there may be a case where the positioning result is between two, or three, or four regions, such as between the region a and the region B, or between the region a, the region B, and the region C, or between the region a, the region B, the region C, and the region D therebetween, and then two regions, or three regions, or four regions closest to the positioning result are taken as the target regions.
In another optional embodiment, in order to quickly acquire the target interest point closest to the user, the client determines, according to the positioning result, the interest point whose distance from the positioning result is smaller than the distance threshold as the target interest point. The distance threshold here may be a length or a width of a predetermined size, or may be set according to actual conditions.
For example, assuming that the displayed map is divided into six areas, i.e., an area a, an area B, an area C, an area D, an area E, and an area E, as shown in fig. 7B, after the positioning result of the user is obtained, it is first determined to which area the positioning result of the user belongs in the map, and when the positioning result is within the area a and another one or more areas are smaller than the distance threshold, then the area smaller than the distance threshold is also a target area in addition to the area a being one of the target areas.
Step 604: the client presents the service information of the target interest point in the map.
Before presenting the service information of the target interest point, the service information needs to be rendered, and the rendering mode can be used for rendering the service information of the interest point according to actual requirements, which specifically includes the following steps:
the first method is as follows: rendering service information for all candidate points of interest
In an alternative embodiment, the service information of each candidate interest point can be rendered according to the actual requirement of the user, so that an image representing the service information is presented in the map, and the user can see the service information of enough interest points in the map.
For example, service information of all candidate interest points around the positioning result of the user is rendered, in other words, the candidate interest points around the user are assumed to be places such as a market supermarket, a restaurant, a gymnasium, a swimming pool and the like, and then the client renders introduction videos and promotion information of the places to obtain corresponding AR service information, wherein the AR service information includes multi-service information, AR electronic tickets and the like, and the AR electronic tickets include AR discount tickets, AR red envelope tickets and the like. Thus, the user can see the introduction videos and the AR electronic coupons of all the surrounding candidate interest points in the map picture.
The second method comprises the following steps: rendering service information for accessed points of interest
In an alternative embodiment, for more targeted display, the accessed target interest point is determined first, and then the service information of the corresponding target interest point is rendered according to the accessed target interest point, so that an image representing the service information is presented in the map.
For example, the target point of interest visited by the user is determined according to the dwell time of the user and/or whether the distance to the point of interest is less than a distance threshold. For example, assuming that there are A, B and C for the places closer to the user, where the location result of the place A is closest to the user, then the place A is used as the target interest point visited by the user, and the promotion information, such as the promotion red envelope, is rendered; alternatively, the length of time that the user stays at the locations A, B and C is recorded, and when the length of time of stay is greater than a certain threshold, it indicates that the user performs corresponding activities at the location, such as shopping, fitness or swimming, and assuming that the time of stay at the location a meets the requirement, service information of the location a, such as an AR e-coupon, is rendered.
The third method comprises the following steps: rendering historically accessed points of interest
In an optional embodiment, the service information may be rendered and displayed according to the historical behavior habits of the user, and the service information of the corresponding target interest point is rendered according to the target interest point recorded as being accessed, so that an image representing the service information is presented in the map.
For example, points of interest around the user positioning result and visited historically are displayed, and service information of the points of interest is rendered, for example, the user visits places such as shopping malls, supermarkets, restaurants, gymnasiums and natatoriums, when the user arrives near the places, the client renders introduction videos and promotion information of the places to obtain corresponding AR service information, wherein the AR service information comprises multi-service information, AR electronic tickets and the like, and the AR electronic tickets comprise AR discount tickets, AR red envelope tickets and the like. Thus, the user can see the introduction video and the AR electronic ticket of the accessed interest points in the surrounding in the map picture.
In an optional embodiment, a graphics processor of a host is called in the process of a browser to render service information of a target interest point in a page of the browser, and an interaction effect of the service information is realized by executing a script in the page.
For example, before rendering the service information, a Web Graphics Library (WebGL) or an Embedded system Open Graphics Library (OpenGL ES) version 2.0 is called to render the service information of the target interest point, and the interaction effects such as acquiring a promotion red envelope or opening an introduction video are realized by executing a script in a page.
Therefore, in the traditional intelligent electronic device or the AR device, the map, the corresponding interest points and the introduction videos of the interest points are displayed, and the corresponding AR red packages with enhanced display, such as electronic coupons and the like, are promoted to facilitate the understanding of the corresponding interest of the customer and the corresponding service for obtaining the interest points.
Here, OpenGL ES and WebGL in the embodiments of the present invention are further described, where OpenGL ES is a subset of an OpenGL three-dimensional graphics API, and is designed for an intelligent electronic device and an AR device, such as an embedded device like a mobile phone, a PDA, a game host, and the like; WebGL is a 3D graphics standard that allows the combination of interpreted scripting language (JavaScript) and OpenGL ES 2.0 versions, as shown in FIG. 13, by adding a JavaScript binding of OpenGL ES 2.0, WebGL can provide hardware 3D-accelerated rendering of the hypertext markup language version 5 Canvas (HTML 5 Canvas), which allows 3D scenes and models to be more smoothly presented in a browser with the help of a system graphics card, and also creates complex navigation and data visualization. The WebGL technical standard eliminates the trouble of developing web page-specific rendering plug-ins, can be used to create web site pages with complex 3D structures, and can even be used to design 3D web games, and the like.
Step 605: the client responds to the request for using the target point of interest using the service information.
Here, according to different types of service information, step 605 can be divided into the following two cases:
scenario one: the service information being multimedia information
In an alternative embodiment, the service information may include multimedia information associated with the target point of interest; presenting a location of a target point of interest in a map; and presenting the multimedia information associated with the target interest point in the map in response to the operation aiming at the position of the target interest point.
For example, after the geographic position of the user is determined according to the positioning result, or after the user selects a geographic position containing an interest point, the interest points around the geographic position are presented in the map, and when an operation aiming at the position of the target interest point is received, corresponding multimedia information is presented at the adjacent position of the target interest point in the map display interface; or, in order to facilitate the user to click and play, check introduction for multimedia information, and check other interest points while playing multimedia, the display interface may be divided into a map display area and a media wave playing interface to display a map and multimedia respectively, wherein the map display area displays the map and corresponding interest points, and the media playing interface displays multimedia information. Therefore, when the user wants to view service information of a nearby target interest point, such as business or commodity introduction of a merchant, in order to better show the characteristics of the merchant, in this case, the introduction information can be presented in a multimedia manner. In addition, the user can search for a point of interest in a certain area, such as a gymnasium, and can conveniently view the introduction video of the gymnasium.
Scenario two: service information is electronic ticket
In another optional embodiment, the service information comprises an electronic ticket corresponding to the target interest point; presenting a corresponding electronic ticket at the position of the target interest point in the map; acquiring the electronic ticket in response to the operation on the electronic ticket; the service is requested using the acquired electronic ticket in response to the operation of the service using the target point of interest.
For example, after the geographic position of the user is determined according to the positioning result, or after the user selects a geographic position containing an interest point, a corresponding electronic ticket is presented at the position of the target interest point in the map, and the user can click the electronic ticket to collect or use the electronic ticket, wherein the electronic ticket can be independently displayed in the map, and the multimedia information can also be simultaneously displayed near the electronic ticket; and when receiving a service operation of the user for using the interest point, using the obtained electronic ticket to perform corresponding payment service.
In an alternative embodiment, the method of using the payment service of the electronic ticket is: determining an offer amount in the electronic ticket; responding to a payment request for a service using the target point of interest using the coupon amount in the electronic ticket. The electronic ticket may be an AR red envelope ticket, an AR discount ticket, an AR membership ticket, or the like.
For example, in the process of closing a check-out after consumption in a shopping mall, a rest place or a restaurant, after a user clicks promotion information (such as an electronic ticket or a red envelope ticket) in an electronic map or a browser, a payment client is automatically called out, and exemption is automatically realized according to the discount amount or discount of the electronic ticket.
In an alternative embodiment, for a merchant, corresponding graphics and video advertisements may be uploaded, and the implementation method is as follows: receiving service information to be uploaded to a map database, determining interest points corresponding to the received service information according to positioning results of the received service information, and uploading identifiers of the determined interest points and the corresponding received service information to the map database, wherein the identifiers can be names or other identification modes of the interest points.
For example, a merchant opens a corresponding website or other application program by using an intelligent electronic device, such as a mobile phone, a notebook computer, a tablet computer, and the like, starts to take pictures and/or record videos, and then identifies the coordinates of the merchant according to the positioning result of the client or the information related to the position in the client; and finally, uploading the recorded video and/or picture and the information of the electronic ticket or the electronic red packet to a server for storage together with the coordinates of the merchant. It should be noted that the coordinate of the merchant and the information of the video, the picture, the electronic ticket, and the electronic red packet establish an association relationship, so that when the user arrives at the area, the corresponding display is performed according to the positioning result.
When a user browses a webpage by using a mobile phone to look at a map, the user hopes to carry out some prompts according to the longitude and latitude of coordinates on the map, such as popping up food in a certain area according to the coordinates and some video introductions of a shopping center, and presents a red envelope provided by a shop on a screen by combining with an AR technology to attract customers, so that the activity of the shop is increased. However, for some specific scenes, such as shopping malls, restaurants and leisure and entertainment venues, the currently used electronic maps and street view maps are usually introduced by pictures and characters, and the pictures and the characters are difficult to express their features visually, so that it is difficult to find out a bright spot that can attract the eyes of a customer by searching for a specific scene in a certain area according to such a manner, in view of this, an effective solution is provided in the embodiment of the present invention, as shown in fig. 8 and 9, where fig. 8 is an implementation schematic diagram of uploading video information at a merchant end provided by the embodiment of the present invention, and the map processing method may include the following steps:

Step 803: and uploading the video.
And after the merchant successfully records the video, clicking a corresponding uploading button, and uploading the recorded video to the server.
Step 804: the coordinates of the merchant end are identified.
When the video is recorded, the video contains position information, so that the coordinate identification of the merchant terminal can be determined according to the position information in the video; in addition, during uploading, a Positioning Service may be called to determine the Location of the merchant, where the Positioning Service may be a Global Positioning System (GPS) or a base station Positioning Service (LBS).
Step 805: and storing the information of the video and the coordinates to a server.
Here, the recorded video is uploaded to a server through a website, and at this time, the latitude and longitude coordinates of a merchant are inquired through a positioning service, such as a map open API provided by various internet service providers; then, the server establishes a database table with the name of the merchant as a main Key (Key), and stores the longitude and latitude and video data corresponding to the Key as a Value (Value).
Referring to fig. 10, fig. 10 is a schematic flow chart illustrating an implementation of another map processing method provided in the embodiment of the present invention, where the map processing method may include the following steps:
step 1001: and logging in the client.
Here, the client refers to a client used by a general user; it should be noted that the client may be the same client as the merchant, that is, the client provides the functions and modules required by the merchant and the general user; or may be two different versions of the client.
Step 1002: and browsing the Web map.
The method comprises the steps that a user browses a Web map, position information of the user is detected in the map, and interest points around the user are obtained according to the detected position information; or, the user browses the Web map, specifies a map position, and acquires the interest point of the position according to the specified map position.
Step 1003: a map location is selected.
Here, the selection map location may be location information of the user, or location information specified in the map by the user.
Step 1004: a store is selected.
After the map position is determined, corresponding interest points and service information of the interest points are displayed in the map, wherein the interest points comprise various shops such as shopping malls, supermarkets, restaurants and leisure and entertainment places; the service information may be an introduction video and an electronic ticket or a red pack ticket corresponding to the shop.
And selecting the corresponding shop according to the selection instruction of the user, and highlighting the corresponding video and the electronic ticket icon.
Step 1005: the video is pulled from the server and popped up.
Here, when the user clicks the icon of the video, and then pulls the video from the server to play, here, the video may be displayed in full screen or non-full screen.
Step 1006: the ok to play button is selected.
When the user selects the confirm play button, the video starts to be played.
Step 1007: the AR coupon is popped up.
When the user clicks the AR red packet icon, corresponding red packet information, such as a discount coupon, a discount coupon or a red packet coupon, is popped up.
Step 1008: a coupon is obtained.
To further introduce the client in the embodiment of the present invention, the client sets up a stack according to the location, stores points of interest (e.g., shops) accessed, attended to, and purchased by the user(s) at the location in the stack, and displays the points of interest through the LRU algorithm. For example, when a user browses a Web map through an application program (APP), after selecting a location, the client may pop up some interest points such as store categories, such as food, shopping mall, and fitness, according to the user's selection habits.
In addition, the client may also use the stack to save the number of points of interest (e.g., shops) that the user visits, pays attention to, and purchases. When a user accesses, concerns and/or purchases the interest points, if the interest points are not stored in the stack, the number of the interest points is pressed to the top of the stack; if the interest points are saved in the stack, the interest points are lifted to the top of the stack; and when the memory is insufficient, removing the interest points at the bottom of the stack. Thus, the stack top is always the number of the latest visited interest point, and the stack bottom is the latest and oldest visited interest point, as shown in fig. 11, fig. 11 is a schematic diagram of stack and stack data processing provided by the embodiment of the present invention.
Here, the processing of data in the stack in fig. 12 is described with reference to fig. 11, where fig. 12 is a schematic flowchart of stack data processing according to an embodiment of the present invention, and therefore, the processing of data in the stack may include the following steps:
step 1201: new data is inserted at the head of the linked list.
Step 1202: whenever a cache hits (i.e., the cache data is accessed), the data is moved to the head of the linked list.
Step 1203: when the linked list is full, the data at the tail of the linked list is discarded.
In this manner, data for points of interest that have been accessed most recently will be retained, while data for points of interest that have been accessed least frequently will be discarded.
Here, the rendering tool in the embodiment of the present invention is further introduced, and the client renders the coupon through WebGL, where the rendering is performed using WebGL, which perfectly solves two problems of the existing Web interactive three-dimensional animation: firstly, the Web interactive three-dimensional animation is manufactured through an HTML script without the support of any browser plug-in; second, it utilizes underlying graphics hardware acceleration functions for graphics rendering, which is implemented via a unified, standard, and cross-platform OpenGL interface.

The WebGL technical standard eliminates the trouble of developing web page-specific rendering plug-ins, can be used to create web site pages with complex 3D structures, and can even be used to design 3D web games, and the like.
Referring to fig. 14, fig. 14 is a schematic diagram of the programmable pipeline of WebGL in accordance with an embodiment of the present invention, which illustrates specific locations of a vertex shader and a fragment shader in the programmable pipeline and a call sequence of an entire API, and this schematic diagram illustrates a flow processing essence of the programmable pipeline: the data stream goes from the application to the vertex processor, then to the fragment processor, and finally to the frame buffer.
After the WebGL rendering is completed, the rendered picture needs to be inverted and then output, and if the rendered picture is not inverted, the pasted picture is found to be inverted like pasting a 'good' word, because the t axis in the WebGL texture coordinate system and the y axis in the image coordinate system are opposite in direction. The image coordinate system is the 4 th coordinate system encountered, with the coordinate axis/origin being the same as the Canvas coordinate system.
