All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The resource refers to a resource which exists in an electronic account, is subject to electronic commerce and can circulate on the internet, and includes but is not limited to electronic money, electronic coupons and the like. Electronic accounts herein may include, but are not limited to: electronic bank cards, internet banking, internet payment accounts, and the like. Resource transfer refers to the process by which a user (i.e., a consumer) transfers a resource from a first electronic account (colloquially referred to as the consumer's electronic account) to a second electronic account (colloquially referred to as the merchant's electronic account) after purchasing or experiencing a service provided by the merchant. The service may refer to a virtual service or a physical service, and the virtual service includes but is not limited to: gaming equipment, advisory services, housekeeping services, etc., and the physical services include, but are not limited to: clothing, electronic products, and the like. The process of resource transfer generally includes three phases: (1) a resource transfer request stage; (2) a generation stage of resource information; (3) and (4) transferring the resource. The above stages will be described in detail with reference to fig. 1 and 2.
Referring to the resource transfer system shown in fig. 1, the system may include a first terminal, a server, and a second terminal; wherein: the first terminal and the second terminal are both user-oriented terminals, and the first terminal may be a terminal oriented to a user (called a consumer) performing the resource transfer operation, that is, the first terminal is specifically a terminal used by the consumer for performing the resource transfer operation. The second terminal may be a terminal facing a user (called a merchant) performing the resource retrieving operation, that is, the second terminal is specifically a terminal used by the merchant for performing the resource retrieving operation. The first terminal can be smart devices such as a smart phone, a tablet computer, a portable personal computer, a smart watch, a bracelet and a smart television, and the second terminal can be a smart payment terminal, such as a point of sale (POS).
The server may be an independent server, a server cluster composed of several servers, or a cloud computing center. The server can provide resource transfer service for the first terminal and the second terminal. In one implementation, the server may be a backend server of the application, such as: the server can be a background server of the payment application program, and the first terminal and the second terminal can interact with the server through the application program, so that a resource transfer process is realized. In another implementation manner, the server may be a dedicated server with resource transfer capability, and the first terminal and the second terminal may interact with the server in a wired or wireless manner, so as to implement a resource transfer process.
based on the system shown in FIG. 1, please refer to the resource transfer process shown in FIG. 2, which includes the following steps S1-S8:
S1, the first terminal generates a resource transfer request.
S2, the first terminal sends a resource transfer request to the server.
steps S1-S2 belong to the resource transfer request phase. At this stage, after the consumer experiences or purchases the service provided by the merchant, the resource needs to be transferred to the merchant. The first terminal may output the interface for the resource transfer operation in various user interfaces, which may include, but are not limited to: a service page of an application, such as a payment interface of a payment application; or a web interface, such as a forum space, etc. The interface may be a key or an option, the consumer may invoke the parameter configuration interface by operating the interface (e.g., pressing the key or selecting the option), and set a parameter for resource transfer in the parameter configuration interface, and the first terminal may obtain the parameter set by the consumer from the parameter configuration interface. This parameter typically includes: an identifier of the consumer, and the like, wherein the identifier of the consumer is used for finding the electronic account of the consumer; the identification may include user identification (e.g., a user account in instant messaging software, a registered user account in payment software, a user account in a general application, or a user account in a web page), device identification used by a user (e.g., a mobile phone number, a serial number of a mobile phone, etc.), or electronic account identification (e.g., an electronic bank card number, an internet banking account number, an internet payment account number, etc.). After obtaining the parameters configured in the parameter configuration interface by the consumer, the first terminal generates a resource transfer request and sends the resource transfer request to the server, wherein the parameters can be carried in the resource transfer request.
and S3, the server generates resource information according to the resource transfer request.
S4, the server sends the resource information to the first terminal.
steps S3-S4 belong to the generation phase of resource information. At this stage, when the server receives the resource transfer request, it generates resource information and returns the resource information to the first terminal. The resource information may include a resource transfer code, an effective time period of the resource transfer, and the like, where the resource transfer code may refer to a number of the current resource transfer, and the resource transfer code is associated with an electronic account of the consumer; the effective time period of resource transfer refers to a time period in which the resource transfer code is in an effective state, that is, in the effective time period of resource transfer, the resource transfer code is effective, that is, the resource transfer code can be used for transferring resources; outside the resource transfer valid period, the resource transfer code is invalid, i.e., the resource code cannot be used to transfer the resource.
And S5, the first terminal generates a graphic code according to the resource information.
s6, the second terminal identifies the graphic code in the first terminal to obtain the resource information.
and S7, the second terminal generates a resource getting request according to the resource information and the resource getting parameters.
And S8, the second terminal sends the resource getting request to the server.
s9, the server executes response processing to the resource retrieval request.
Steps S5-S9 belong to a resource transfer phase, in which the first terminal may generate a graphic code according to the resource information, i.e. the graphic code may include a resource transfer code. The graphic code is a geometric figure of black and white graphic recording data distributed on a plane (such as a two-dimensional direction) according to a certain rule. And the second terminal identifies the graphic code in the first terminal to obtain the resource information. Meanwhile, the second terminal may output an interface for resource pickup operation in various user interfaces, where the user interfaces may include but are not limited to: a service page of an application, such as a payment interface of a payment application; or a web interface, such as a forum space, etc. The interface may be a key or an option, the merchant may invoke the parameter configuration interface by operating the interface (e.g., pressing the key or selecting the option), and set a parameter for resource pickup in the parameter configuration interface, and the second terminal may obtain the resource pickup parameter set by the merchant from the parameter configuration interface. This resource procurement parameter typically includes: the electronic account management system comprises an identification of a merchant, a target resource amount, a resource transfer reason and the like, wherein the identification of the merchant is used for finding the electronic account of the merchant; the identification may include user identification (e.g., a user account in instant messaging software, a registered user account in payment software, a user account in a general application, or a user account in a web page), device identification used by a user (e.g., a mobile phone number, a serial number of a mobile phone, etc.), or electronic account identification (e.g., an electronic bank card number, an internet banking account number, an internet payment account number, etc.). The target resource amount in the resource pickup parameter refers to the total amount of resources that the server needs to deduct from the electronic account of the consumer, for example: the target resource amount in the resource pickup parameter is 10 dollars in electronic money, and the server needs to deduct 10 dollars in electronic money from the consumer's electronic account. The resource transfer reason is to explain why the resource needs to be transferred from the electronic account of the consumer, such as buying XX clothes and the like. Further, the second terminal may generate a resource getting request, where the resource getting request carries resource information and resource getting parameters, and send the resource getting request to the server; the server responds to the resource getting request and executes the following processing: (1) judging whether the resource transfer condition is met according to the resource getting request specifically includes: and judging whether the current time is within the effective time period of resource transfer, if not, sending prompt information to the first terminal and the second terminal by the server, wherein the prompt information is used for prompting the failure of resource transfer. If the target resource amount contained in the resource pickup parameter is greater than the preset threshold value within the effective time period, the service can judge whether the target resource amount contained in the resource pickup parameter is greater than the preset threshold value, wherein the preset threshold value can be the remaining total amount of the resources in the electronic account of the consumer or the maximum amount of the resources allowed to be transferred by one resource transfer operation set by the server; if the resource transfer condition is greater than the preset value, determining that the resource transfer condition is not met, and sending prompt information to the first terminal and the second terminal by the server, wherein the prompt information is used for prompting the failure of resource transfer; if not, determining that the resource transfer condition is met; entering (2) the server to determine the electronic account of the consumer according to the resource transfer code, and deducting the resource equivalent to the target resource amount contained in the resource drawing parameter from the electronic account of the consumer; and adding the deducted resources into the electronic account corresponding to the merchant identifier to complete resource transfer. After completing the resource transfer, the server may return a transfer result to the first terminal and the second terminal.
In order to improve the efficiency of resource transfer, an embodiment of the present invention provides a new resource transfer method, which improves the basic processing flows shown in S1-S9 as follows: and introducing a verification operation on whether the graphic code is positioned in the identification range of the identification operation in the resource transfer stage, and outputting prompt information when the graphic code exceeds the identification range so as to prompt the adjustment of the graphic code to the identification range. Through the improvement, the embodiment of the invention can quickly finish the resource transfer and improve the efficiency of the resource transfer. And the consumer can complete the resource transfer independently through the guidance of the prompt message. The communication time between the merchant and the consumer is reduced, and the resource transfer experience is improved.
please refer to fig. 3, which is a flowchart illustrating a resource transfer method according to an embodiment of the present disclosure, where the resource transfer method may be applied to an electronic device. The electronic device may refer to a second terminal in fig. 1, and the method may include the following steps S101 to S104.
s101, when a target object is detected in an area with a distance between the target object and the image pickup device being smaller than a preset distance threshold, the image pickup device is called to shoot the target object to obtain a preview image. When a consumer needs to transfer resources to a merchant, the consumer can display a target graphic code through a first terminal, the target graphic code comprises resource information, the resource information can comprise a resource transfer code and an effective time period for resource transfer, and the target graphic code is allowed to be identified so as to acquire the resource information contained in the target identification code. Correspondingly, the electronic equipment can comprise a camera device, the camera device can be used for monitoring the front, namely the camera device can detect the distance between a front object and the camera device, so that whether an object is close to the camera device or not is judged. Generally, when the distance between the target object and the camera device is greater than or equal to the preset distance threshold, the camera device cannot shoot a clear target object, and meanwhile, when the distance between the target object and the camera device is smaller than the preset distance threshold, it generally indicates that the consumer wants to complete resource transfer by adopting a code scanning mode. Therefore, when the target object is detected in the area with the distance between the electronic equipment and the camera device being smaller than the preset distance threshold, the electronic equipment can call the camera device to shoot the target object to obtain the preview image, and therefore resources of the camera device can be saved. The target object may refer to any object whose distance from the image capturing device is less than a preset distance threshold, or the target object may refer to an object carrying a target graphic code, such as the first terminal, and the image capturing device may include, but is not limited to: multispectral imager, hyperspectral imager, visible light camera and infrared camera, 3D camera etc.. Optionally, the electronic device may use multiple resource transfer modes, such as a face recognition mode and a graphic code recognition mode, where the face recognition mode is to obtain the identifier of the consumer according to a face recognition mode, so as to complete resource transfer according to the identifier of the consumer. The pattern code identification mode is to acquire resource information in a pattern code identification mode and finish resource transfer according to the resource information. Optionally, when the electronic device is in the face recognition mode, the face is photographed to obtain a face image, and whether the face in the face image has integrity is determined. If the integrity indicates that the consumer wants to adopt the face recognition mode to perform resource transfer, the face is recognized, and the face characteristic information is obtained. And determining a user identifier associated with the face feature information, and executing resource transfer operation according to the associated user identifier. If the integrity is not present, which indicates that the face is blocked by an article (such as a smart phone), that is, the consumer wishes to perform resource transfer in the pattern code recognition mode, the method may switch to the pattern code recognition mode, and perform step S101. The flexible switching between the resource transfer modes can be realized, manual switching by a user is not needed, and the convenience of resource transfer is improved.
and S102, if the preview image comprises the target graphic code, determining whether the target graphic code is located in the identification range of the identification operation according to the preview image.
In order to improve the resource transfer efficiency, the electronic device may determine whether the preview image includes the target graphic code according to feature information of the target graphic code, where the feature information includes information such as a shape and a color of the target graphic code. If the preview image does not include the target graphic code, the electronic equipment can end the process; if the preview image includes the target graphic code, it may be determined whether the target graphic code is located within the identification range of the identification operation according to the preview image, and if the target graphic code is located within the identification range, which indicates that the probability that the identification operation of the electronic device on the target graphic code is successful is relatively high, step S104 is executed. If the target graphic code is beyond the identification range, which indicates that the probability of successful operation of the electronic device on the target graphic code is relatively low or the electronic device cannot successfully operate on the target graphic code, step S103 may be executed. The target graphic code located in the recognition range may mean that the image information of the graphic code satisfies the recognition condition, and the image information includes, but is not limited to, at least one of the following: the size and the position of the target graphic code in the preview image and the distance between the target graphic code and the camera device; the fact that the target graphic code exceeds the identification range means that the image information of the target graphic code does not meet the identification condition. The successful identification operation means that the target graphic code can be identified and complete resource information in the target graphic code is obtained; the failure of the identification operation means that the target graphic code cannot be identified, or the target graphic code can be identified, but only part of the resource information in the target graphic code can be acquired.
and S103, if the target graphic code exceeds the identification range, outputting prompt information, wherein the prompt information is used for prompting the target graphic code to be adjusted to the identification range.
If the target graphic code is beyond the identification range, the electronic device may output a prompt message for prompting the target graphic code to be adjusted within the identification range, where the prompt message may include, but is not limited to: speech, text, images. The adjustment of the target graphic code may refer to adjusting a position, a size, and the like of the target graphic code.
and S104, identifying the target graphic code in the identification range to obtain resource information to be transferred, and executing transfer operation according to the resource information.
after the target graphic code is adjusted to be within the identification range, the electronic device can identify the target graphic code within the identification range to obtain resource information, and perform a transfer operation according to the resource information.
in the embodiment of the invention, when the identification operation of the target graphic code is detected, a camera device is called to shoot the target graphic code to obtain a preview image, and whether the target graphic code is located in the identification range of the identification operation can be determined according to the preview image; when the target graphic code exceeds the identification range, the prompt information is output and can prompt a user to quickly adjust the target graphic code to the identification range, so that the identification efficiency of the target graphic code is improved, and the success probability of the identification operation of the target graphic code is improved. Further, when the target pattern code is adjusted to be within the identification range, the resource information is obtained by identifying the target pattern code within the identification range, and the resource transfer operation is executed according to the resource information, so that the resource transfer efficiency can be improved, and the success probability of the resource transfer can be improved. Through the guidance of the prompt message, the independent resource transfer of the consumer can be achieved, the communication time between the merchant and the consumer is shortened, and the resource transfer experience is improved.
in one embodiment, step S102 includes steps S11 and S12 as follows.

s12, determining whether the target graphic code is within the recognition range according to the image information.
in steps s11 and s12, when the distance between the target graphic code and the image capture device is too large or too small, or the target graphic code deviates from the image capture device, or the size of the target graphic code in the preview image is too large or too small, the electronic device has a relatively small probability of successful recognition operation of the target graphic code. That is, the recognition range is related to the image information of the object graphic code, so the electronic equipment can acquire the image information of the object graphic code according to the preview image and determine whether the object graphic code is located in the recognition range according to the image information.
In this embodiment, the image information includes a distance between the target graphic code and the image capturing device, and the preview image includes a first image and a second image; step s11 includes the following steps s21-s 23.
and s21, acquiring the two-dimensional coordinate information of the first characteristic point of the target graphic code from the first image.

in steps s21-s22, the first image may refer to a color image, the second image may refer to a depth image, the color image may include an image of two-dimensional pixel coordinate information of the target graphic code, and the depth image may refer to an image including depth information of the target graphic code, that is, the depth image may be used to reflect a distance between the target graphic code and the image capture apparatus. The electronic device may acquire two-dimensional coordinate information of a first feature point of the target graphic code from the first image, where the two-dimensional coordinate information may refer to two-dimensional pixel coordinate information, and the first feature point may refer to any feature point of the target graphic code, or the first feature point may refer to a feature point at a center position of the target graphic code. Further, the electronic device may acquire depth information of a second feature point of the target graphic code from the second image. The second feature point is matched with the first feature point, that is, the second feature point and the first feature point have the same position in the target graphic code, and the depth information may include a distance between the target graphic code and the image capturing device in the camera coordinate system.
s23, determining the distance between the target image code and the camera device according to the two-dimensional coordinate information of the first feature point and the depth information of the second feature point.
When the first feature point is a feature point at the center position of the target graphic code, the electronic device may determine the distance between the target graphic code and the camera device according to the two-dimensional coordinate information of the first feature point and the depth information of the second feature point. When the first feature point is any feature point of the target graphic code, the electronic device may calculate an average two-dimensional pixel coordinate of the feature point of the target graphic code in the first image, calculate an average depth of the feature point of the target graphic code in the second image, and determine a distance between the target graphic code and the image capturing device according to the average two-dimensional pixel coordinate and the average depth.

Further, the three-dimensional coordinate information of the target graphic code in the world coordinate system is determined according to the shooting parameters and the three-dimensional coordinate information of the target graphic code in the camera coordinate system. Then, the distance between the target graphic code and the camera is determined by using the position information of the camera and the three-dimensional coordinate information of the target graphic code in the world coordinate system.
In this embodiment, the image information includes a distance between the target graphic code and the image capturing device, S102, which includes: the recognition range can be [ a first distance threshold value and a second distance threshold value ], that is, if the distance between the target graphic code and the camera device is greater than or equal to the first distance threshold value and is less than or equal to the second distance threshold value, the target graphic code is considered to be in the recognition range; this indicates that the distance comparison between the target graphic code and the image capturing device is suitable for the identification operation of the target graphic code, i.e., the success probability of the identification operation of the target graphic code is relatively high. If the distance between the target graphic code and the camera device is smaller than a first distance threshold value, the target graphic code is too close to the camera device; if the distance between the target graphic code and the camera device is larger than a second distance threshold value, the target graphic code is far away from the camera device; the situation of being too close or too far exceeds the identification range of the identification operation, which reduces the success probability of the identification operation on the target graphic code, and then the target graphic code is considered to be beyond the identification range. The first distance threshold is smaller than the second distance threshold, and the first distance threshold and the second distance threshold may be manually set by a user, or may be default values in the electronic device, for example, the first distance threshold may be 5cm, and the second distance threshold may be 20 cm.

Step S102 includes: the recognition range may be [ a first size threshold, a second size threshold ], that is, if the size of the target graphic code in the preview image is greater than or equal to the first size threshold and less than or equal to the second size threshold, the target graphic code is considered to be within the recognition range; this indicates that the distance comparison between the target graphic code and the image capturing device is suitable for the identification operation of the target graphic code, i.e., the success probability of the identification operation of the target graphic code is relatively high. If the size of the target graphic code in the preview image is smaller than a first size threshold, the target graphic code is far away from the camera device; if the size of the target graphic code in the preview image is larger than a second size threshold, indicating that the distance between the target graphic code and the camera device is too close; the situation of being too close or too far exceeds the identification range of the identification operation, which causes the success probability of the identification operation of the target graphic code to be reduced, and then the target graphic code is considered to be in the identification range. The image information is considered to be within the recognition range; if the size of the target graphic code in the preview image is larger than the first size threshold or smaller than the second size threshold, it indicates that the distance between the target graphic code and the image pickup device is too close or too far, and at this time, the success probability of the identification operation on the target graphic code is relatively low, and therefore, the target graphic code is determined to be beyond the identification range of the identification operation. Wherein the first size threshold is less than the second size threshold.

In this embodiment, the position of the target graphic code in the preview image; step S102 includes: the recognition range may be a preset image area, and the preset image area may refer to an area where the electronic device scans the graphic code. And if the position of the target graphic code in the preview image is not located in the preset area, indicating that the target graphic code is deviated from the identification range, namely determining that the target graphic code is beyond the identification range of the identification operation. And if the position of the target graphic code in the preview image is located in the preset area, indicating that the target graphic code is not deviated from the identification range, namely determining that the target graphic code is beyond the identification range of the operation.

Further, the preview graph is displayed in a preview frame to prompt a user to quickly adjust the target graph code to be within the identification range according to the preview frame. Here, adjusting the target graphic code may include moving the target graphic code left or right or back and forth.
