As used in this disclosure and the appended claims, the singular forms "a," "an," and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise. It should also be understood that the term "and/or" as used herein refers to and encompasses any and all possible combinations of one or more of the associated listed items.
It is to be understood that although the terms first, second, third, etc. may be used herein to describe various information, such information should not be limited to these terms. These terms are only used to distinguish one type of information from another. For example, first information may also be referred to as second information, and similarly, second information may also be referred to as first information, without departing from the scope of the present disclosure. The word "if" as used herein may be interpreted as "at … …" or "when … …" or "in response to a determination", depending on the context.
The graphic code may be a graphic identifier arranged according to a certain rule by using a certain specific graphic to express certain information. For example, the graphic code may be a two-dimensional code, a bar code, or the like. The graphic code can be used for information acquisition, website skip, advertisement push, preferential promotion and the like. The scanning user (also called as a viewer) can scan the graphic code through the scanning terminal, so as to obtain the information corresponding to the graphic code. The graphic code can be applied to various fields and scenes, for example, the graphic code is displayed on a large screen, so that a scanning user can obtain corresponding information by scanning a two-dimensional code through a scanning terminal.
However, the situation that the scanning user is too close to the screen and the two-dimensional code is too large, or the scanning user is too far away from the screen and the two-dimensional code is too small, or the screen is large and the two-dimensional code is at a screen position where the scanning user cannot scan, and the like often occurs, and at this moment, the user is difficult to scan the graphic code on the screen. The user often needs to scan the graphic code by means of being far away from the display screen, being close to the graphic code by means of external force and the like, the efficiency of visible scanning of the graphic code is low, and inconvenience is brought to the user.
As shown in fig. 1, fig. 1 is a scene diagram showing a graphic code according to the present disclosure. Under this scene, because the display screen is great, user's cell-phone can only scan A position area on the display screen, and the two-dimensional code is in the upper left corner of display screen, and the user need adopt modes such as taking the ladder just can scan the two-dimensional code, otherwise can't scan the two-dimensional code through the cell-phone, then can't acquire the information that the two-dimensional code corresponds.
In order to avoid the defect that the two-dimensional code in the display screen cannot be scanned in the related art, the target position area on the display screen which can be scanned by the scanning terminal is determined firstly, the graphic code on the display screen is adjusted according to the target position area, so that the adjusted graphic code is displayed in the target position area, and the target position area is an area which can be scanned by a user, so that the user can quickly scan the two-dimensional code, further information corresponding to the two-dimensional code is acquired, the scanning efficiency is improved, and convenience is brought to the user.
As shown in fig. 2, fig. 2 is a flowchart illustrating a graphic code presentation method according to an exemplary embodiment of the present disclosure, which may include the following steps:
in step 201, a target location area on a display screen that can be scanned by a scanning terminal is determined.
In step 202, the graphic code on the display screen is adjusted according to the target location area, so that the adjusted graphic code is displayed in the target location area.
The embodiment of the present disclosure can be applied to a display screen, which is a display device and has not only a display capability but also an information processing capability. For example, the display screen may be a display screen, a tiled wall, or the like. The display screen the currently displayed picture may comprise text information, image information, video information, etc. The scanning terminal in the embodiments of the present disclosure is an electronic device with a scanning function, for example, the scanning terminal may be a smart phone, a tablet computer, a PDA (Personal Digital Assistant), a smart band, a smart watch, and so on.
In the present disclosure, the target position area is an area of the display screen that the scanning terminal can scan. When the display screen is larger and the scanning user is closer to the display screen, the scanning terminal can scan only a partial area on the display screen, and when the display screen is smaller or the scanning user is farther from the display screen, the scanning terminal can scan the whole area of the display screen.
This disclosure lists several ways of determining the target location area on the display screen that the scanning terminal can scan:
in an optional implementation manner, the determining a target location area on a display screen that can be scanned by a scanning terminal includes:
the image of the person including the scanning user is photographed by a camera device provided on the display screen.
And determining the relative position of the scanning user and the display screen according to the person image.
And determining a target position area on a display screen which can be scanned by a scanning terminal according to the relative position, wherein the scanning terminal is a terminal held by the scanning user.
In the embodiment, a camera device may be disposed on the display screen, and the image of the person including the scanned user is captured by the camera device. The timing when the image pickup device picks up the person image may be that a preset shooting condition is satisfied. Specifically, when the preset shooting condition is met, the image of the person including the scanning user is shot through the image pickup device arranged on the display screen.
The preset shooting condition may be that a preset time interval is reached, that a person is scanned, or that a scanning request sent by a scanning terminal is received. For example, the scanning terminal may log in a preset application program, send a scanning request to the display screen through the preset application program, and shoot a person image including a scanning user through the camera device arranged on the display screen only when the display screen receives the scanning request, so that resource waste caused by real-time shooting by the camera device is avoided.
The scanning user is a user who scans the graphic code by using the scanning terminal. The photographing device photographs a person image including a scanning user in order to determine a relative position of the scanning user and a display screen, that is, to determine the relative position of the scanning user and the display screen based on the person image.
The relative position may include scanning a distance between the user and the display screen, and may further include scanning a forward projection area of the user on the display screen or scanning a corresponding position of the user on the display screen. Several methods of determining the relative position of the scanning user and the display screen are listed below.
In one example, a contrast object may be provided in the right opposite and lateral directions of the display screen, the relative position of the contrast object to the display screen being known. By comparing the person with the contrast object, the relative position of the scanning user and the display screen can be determined according to the relation between the person in the person image and the contrast object.
In another example, the distance measuring device can be formed by combining a camera and a laser pen, so that the distance between the scanning user and the display screen can be detected.
In another example, the distance between the scanning user and the display screen may also be measured by passive ranging methods such as stereo vision, motion ranging, monocular ranging, and the like. The stereoscopic vision is a stereoscopic perception analysis method simulating human beings, a binocular or multi-view camera observes the same scene at different viewpoints, and two-dimensional images of an object shot by target images at different viewing angles are acquired. The three-dimensional information of the scenery is obtained by calculating the position deviation, namely parallax, among the pixels of the image through the principle of triangulation. The motion distance measurement method can acquire continuous target images at different times or different spatial positions by using a monocular camera, and calculate the distance and other parameters of a scanning user through the time and spatial change of the scanning user in a two-dimensional image sequence. The distance measurement method based on image processing in monocular distance measurement includes a Depth From Focus (DFF) method and a Defocus From Defocus (DFD) method, and the specific test method is not described herein again.
It can be understood that other manners may also be adopted to determine the relative position between the scanning user and the display screen according to the person image, and details are not repeated herein.
After determining the relative position between the scanning user and the display screen, the target position area on the display screen that can be scanned by the scanning terminal can be determined according to the relative position.
In one example, if the relative position includes scanning a forward projection area of the user on the display screen, the forward projection area may be directly determined as a target position area that the scanning terminal can scan onto the display screen.
In another example, the correspondence of the relative position to the position area may be stored in advance. For example, when the relative position includes a distance of the scanning user from the display screen and a forward projection area of the scanning user on the display screen, the positional relationship of the distance, the forward projection area, and the position area is stored in advance. Based on the position area, the position area corresponding to the determined relative position can be determined as a target position area on the display screen which can be scanned by the scanning terminal according to the corresponding relation between the pre-stored relative position and the position area. Therefore, the target position area on the display screen which can be scanned by the scanning terminal is determined according to the corresponding relation and the determined relative position, the method is easy to realize, and the efficiency of determining the position area is improved.
As can be seen from the foregoing embodiments, in the present embodiment, the person image including the scanning user is captured, the relative position between the scanning user and the display screen is determined by analyzing the person image, and the target position area on the display screen that can be scanned by the scanning terminal is determined according to the relative position, so as to achieve positioning of the position area.
In another alternative implementation manner, the determining a target location area on a display screen that can be scanned by a scanning terminal includes:
identification information for identifying the display screen is broadcast.
And receiving the target position area sent by the server.
Wherein the target location area is: and after determining the current display picture of the display screen according to the identification information, the server determines a target position area on the display screen which can be scanned by the scanning terminal according to the relation between the shot image and the current display picture, wherein the identification information and the shot image are sent to the server by the scanning terminal, and the shot image is an image obtained by shooting the picture on the display screen by the scanning terminal.
The display screen may broadcast identification information for identifying the display screen. The identification information may be the name, number, and geographical location information of the display screen, or may be any combination of numbers, character strings, symbols, and the like, as long as the display screen can be uniquely identified.
The display screen may broadcast the identification information via short-range wireless communication techniques such as bluetooth. The purpose of broadcasting the identification information is to allow the service end to identify the display screen by scanning the terminal. Specifically, the scanning terminal can receive the identification information broadcasted by the display screen, shoot the picture on the display screen, send the shot image and the identification information to the server, and the server determines the target position area on the display screen which can be scanned by the scanning terminal according to the shot image and the identification information.
When the scanning terminal needs to scan, a preset application program can be logged in, the camera is called by the preset application program to shoot a picture on the display screen, one shot image can be shot, and multiple shot images can also be shot. The user can photograph at an arbitrary position of the picture on the display screen. The area that can be photographed by the scanning terminal can be considered as an area that can be scanned by the scanning terminal. After the shot image and the identification information are obtained, the scanning terminal can send the shot image and the identification information to the server through a preset application program, for example, a scanning request carrying the shot image and the identification information can be sent to the server, so that when the server receives the scanning request, a target position area on a display screen which can be scanned by the scanning terminal is determined according to the shot image and the identification information.
As to how the server determines the target location area on the display screen that can be scanned by the scanning terminal according to the shot image and the identification information, the present disclosure also provides a location area determining method, as shown in fig. 3, where fig. 3 is a flowchart of a location area determining method shown in the present disclosure according to an exemplary embodiment, and the method may be applied to the server and includes the following steps 301 to 304:
in step 301, a shot image and identification information for identifying a display screen, which are sent by a scanning terminal, are received, wherein the shot image is obtained by shooting a picture on the display screen by the scanning terminal.
In step 302, a currently displayed picture of the display screen is determined according to the identification information.
The server can identify the display screen according to the identification information, and the server can determine the current display picture of the display screen due to the fact that the server is in network connection with the display screen.
In step 303, a target position area on the display screen that can be scanned by the scanning terminal is determined according to the relationship between the shot image and the current display frame.
The shot image is an image obtained by shooting a picture on the display screen, so that a target position area on the display screen which can be scanned by the scanning terminal can be determined according to an overlapped picture of the shot image and the current display picture.
In one example, if the shot image includes the current display frame, the target position area on the display screen that can be scanned by the scanning terminal is a full-screen area of the display screen.
The position area is a full screen area of the display screen, the position of a scanning user far away from the display screen can be estimated, or the size of the display screen is small, and when the graphic code is adjusted subsequently, the graphic code can be amplified so that the scanning user can scan through the scanning terminal.
In one example, if the current display picture includes a shot image, the shot image is compared with the current display picture to determine a position area of the shot image in the current display picture, and a target position area on a display screen which can be scanned by a scanning terminal is determined according to the determined position area.
The current display picture contains the shot image, the shot image is a part of the current display picture, and the position area of the shot image in the current display picture can be determined by comparing the shot image with the current display picture. In one aspect, the determined location area may be directly determined as a target location area that the scanning terminal can scan onto the display screen. On the other hand, the zoom adjustment may be performed according to the determined position region, and the adjustment result may be determined as a target position region on the display screen that can be scanned by the scanning terminal.
For example, when the captured image is an image, after the position area of the captured image in the current display frame is determined, it is estimated that the position area of the captured image that can be scanned on the display screen by the scanning terminal is larger than the position area of the captured image in the current display frame, the position area of the captured image in the current display frame may be enlarged in proportion, and the enlarged area may be determined as a target position area that can be scanned on the display screen by the scanning terminal.
For another example, when the captured image is a plurality of images, after the position area of the captured image in the current display frame is determined, it may be estimated that the position area that the scanning terminal can scan on the display screen is close to the determined position area, so that the determined position area is directly determined as the target position area that the scanning terminal can scan on the display screen.
When the current display picture contains the shot image, the distance from the scanning user to the display screen can be estimated to be short, or the screen is large, and when the graphic code is adjusted subsequently, the graphic code can be moved to the determined position area, so that the scanning user can scan through the scanning terminal.
In step 304, the target location area is sent to the display screen, so that the display screen adjusts the graphic code on the display screen according to the target location area, and the adjusted graphic code is displayed in the target location area.
As can be seen from the above embodiments, in the present embodiment, the server receives the shot image and the identification information, determines the target location area on the display screen that can be scanned by the scanning terminal according to the shot image and the identification information, and implements determination of the location area through the server instead of the display screen, thereby reducing the hardware requirement on the display screen.
For ease of understanding, the present disclosure is described in connection with a server and a scanning terminal. As shown in fig. 4A and 4B, fig. 4A is a diagram of an application scenario of a graphic code presentation method according to an exemplary embodiment of the present disclosure, where the scenario includes a scanning terminal, a server, and a display screen. It is to be understood that only one scanning terminal and display screen are shown in fig. 4A, and are not limited to one in nature, and only one is illustrated here. Fig. 4B is a timing diagram illustrating a graphical code presentation method according to an exemplary embodiment of the present disclosure, which may include the steps of:
1. the display screen broadcasts identification information for identifying the display screen.
2. The scanning terminal receives the identification information broadcast by the display screen and shoots the picture on the display screen.
3. And the scanning terminal sends the shot image and the identification information to the server.
4. And the server determines the current display picture of the display screen according to the identification information, and determines a target position area on the display screen which can be scanned by the scanning terminal according to the relationship between the received shot image and the determined current display picture.
5. And the server side sends the target position area to a display screen.
6. And the display screen adjusts the graphic code on the display screen according to the target position area so as to display the adjusted graphic code in the target position area.
It can be seen from the above embodiments that, the identification information is broadcasted through the display screen, the scanning terminal receives the identification information and sends the shot image and the identification information to the server, and the server can determine the display screen according to the identification information and further determine whether the display screen to be scanned by the scanning user is the display screen identified by the identification information according to the shot image and the current display picture in the display screen, so as to implement double determination and to implement accurate adjustment of the graphic code, so as to display the adjusted graphic code in the location area. Meanwhile, the determination of the position area is realized through a server instead of a display screen, so that the hardware requirement on the display screen is reduced.
In another alternative implementation, the present disclosure also provides another method for determining a target location area on a display screen that can be scanned by a scanning terminal, where the determining the target location area on the display screen that can be scanned by the scanning terminal includes:
and receiving a shot image sent by the scanning terminal, wherein the shot image is an image obtained by shooting a picture on a display screen by the scanning terminal.
And determining the current display picture of the display screen.
And determining a target position area on the display screen which can be scanned by the scanning terminal according to the relation between the shot image and the current display picture.
When a scanning user scans the graphic code on the display screen by using the scanning terminal, the scanning terminal can shoot the picture on the display screen to obtain a shot image, and the shot image is sent to the display screen. As one of the sending modes, the scanning terminal may send a scanning request carrying a shot image to the display screen, so that when the display screen receives the scanning request, the current display frame of the display screen is determined, and the target position area on the display screen that can be scanned by the scanning terminal is determined according to a relationship between the shot image and the current display frame in the scanning request.
Since the shot image is an image obtained by shooting a picture on the display screen, the target position area on the display screen that can be scanned by the scanning terminal can be determined according to the overlapped picture of the shot image and the currently displayed picture.
In one example, if the shot image includes the current display frame, the target position area on the display screen that can be scanned by the scanning terminal is a full-screen area of the display screen.
The position area is a full screen area of the display screen, the position of a scanning user far away from the display screen can be estimated, or the size of the display screen is small, and when the graphic code is adjusted subsequently, the graphic code can be amplified so that the scanning user can scan through the scanning terminal.
In one example, if the current display picture includes a shot image, the shot image is compared with the current display picture to determine a position area of the shot image in the current display picture, and a target position area on a display screen which can be scanned by a scanning terminal is determined according to the determined position area.
The current display picture contains the shot image, the shot image is a part of the current display picture, and the position area of the shot image in the current display picture can be determined by comparing the shot image with the current display picture. On one hand, the determined position area can be directly determined as a target position area which can be scanned on a display screen by the scanning terminal; on the other hand, the zoom adjustment may be performed according to the determined position region, and the adjustment result may be determined as a target position region on the display screen that can be scanned by the scanning terminal.
It can be seen from the above embodiments that, in the present embodiment, the target location area is determined through the display screen, so that the real-time property of determining the target location area can be realized, and the defect that the determination of the target location area is not timely due to network reasons, and further the graphic code is not timely adjusted is avoided.
After the target position area is determined, the graphic code on the display screen can be adjusted according to the target position area, and the purpose of the adjustment is to enable the adjusted graphic code to be displayed in the target position area.
As one of the adjusting means, the adjusting may include moving and zooming, that is, acquiring a location area of the graphic code on the display screen, comparing the target location area with the location area of the graphic code, zooming the graphic code according to the comparison result, and moving the zoomed graphic code to the target location area for displaying. Specifically, the graphic code is zoomed according to the size of the target position area and the size of the graphic code, so that the zoomed size of the graphic code is the size of the graphic code which is suitable for a scanning user to scan by using a scanning terminal; and moving the graphic code according to the position of the position area and the position of the graphic code, and moving the graphic code to the target position area. When the graphic code is moved, the graphic code can be moved to any position in the target position area, or can be fixedly moved to the center in the target position area, and the setting is specifically carried out according to requirements.
It can be seen that the purpose of the movement is to enable the scanning user to scan the graphic code, and the purpose of the scaling is to make the scanning user more convenient to scan the graphic code.
In an optional implementation manner, the target position area is a target coordinate area; the adjusting the graphic code on the display screen according to the target position area so that the adjusted graphic code is displayed in the target position area includes: acquiring a coordinate area of the graphic code on the display screen; and comparing the target coordinate area with the coordinate area of the graphic code, zooming the graphic code according to the comparison result, and moving the zoomed graphic code to the target coordinate area for display.
A specific application example is shown below for explanation. As shown in fig. 4C, fig. 4C is an application scenario diagram of another graphic code presentation method according to an exemplary embodiment of the present disclosure. In the application scenario, the four corner coordinates of the target coordinate area (Camera frame) are: a (X)a，Ya)、b(Xb，Yb)、c(Xc，Yc)、d(Xd，Yd) (ii) a The four angular coordinates of the graphic code (QR frame) on the display screen are: a (X)A，YA)、B(XB，YB)、C(XC，YC)、D(XD，YD)。
Camera frame region width: w1＝Yb-Yc
QR frame region width: w2＝YB-YC
K＝W1/W2
When K is greater than 1, the graphic code needs to be amplified, the amplification factor can be K, or other values close to K, and the amplified graphic code is moved to a target position area; when K is less than 1, the graphic code needs to be reduced, the reduction multiple can be K, or other values close to K, and the reduced graphic code is moved to a target position area; when K is 1, the size of the graphic code may be moved to the target location area without processing.

It can be seen from the above embodiments that the location area is represented by the coordinate area, which improves the efficiency of moving and scaling the graphic code.
In an optional implementation manner, in order to avoid that when the graphic code is moved to the position area, the original image in the position area is used as the background of the graphic code to affect the scanning of the graphic code, the present disclosure may hide the picture on the display screen when the graphic code is moved to the position area, thereby improving the scanning effect. It is understood that other moving manners may be used in practical application, as long as the graphic code can be scanned after being moved.
Further, after the adjustment of the graphic code is completed and the preset time interval is set, the graphic code is restored and displayed. The recovery is to restore the graphic code and inversely adjust the adjusted graphic code. For example, the graphic code is scaled to the original size and moved back to the original position, and the picture on the display screen is displayed, so that the situation that the content of the display screen cannot be viewed by the audience due to long-term hidden picture is avoided, and economic loss is brought to the provider.

Therefore, the two-dimensional code scanning device is convenient for a user to scan the two-dimensional code, and meanwhile, the picture displayed on the display screen is not influenced.
In another alternative implementation, the same image code as the original image code may be displayed directly in the target position area without moving the image code. For example, the graphic code may be displayed on the newly established layer and in the target location area, and the originally displayed layer of the display screen may be covered by the layer. As shown in fig. 4E, fig. 4E is an application scenario diagram of another graphic code presentation method according to an exemplary embodiment of the present disclosure. In the schematic diagram, the scanning terminal can scan a certain target position area below the display screen, and the two-dimensional code is in the upper right corner of the screen which can not be scanned by a scanning user. After the target position area is determined, the two-dimensional code is amplified by the display screen, the amplified two-dimensional code is displayed at the target position area of the new image layer, meanwhile, the original display image layer of the display screen is covered by the new image layer, and the original display image layer is displayed again after a preset time interval. Therefore, the two-dimensional code scanning method is convenient for a user to scan the two-dimensional code, and meanwhile, the picture displayed on the display screen is not influenced.
