Description

圖形碼掃描方法、掃碼支付方法及掃碼設備Graphic code scanning method, scanning code payment method and scanning code device

本說明書一個或多個涉及行動支付領域，尤其涉及一種圖形碼掃描方法、掃碼支付方法及掃碼設備。One or more of this specification relates to the field of mobile payment, in particular to a graphic code scanning method, a scanning code payment method and a scanning device.

目前，隨著行動網際網路技術的快速發展，由於行動支付具有支付簡單、方便、便捷的特點，使得行動支付的應用越來越普及，已經成為人們日常生活中必不可少的一部分。例如，商家使用掃碼槍掃描並識別消費者出示的付款碼，以完成行動支付，因此，掃碼槍已成為在公共場合進行行動支付的主要收款設備。 然而，現有的透過掃碼槍掃描付款碼的過程中，由於消費者和收款人員的身高差、站位距離等原因導致掃碼設備與付款碼之間形成的角度偏差過大，從而出現多次掃碼失敗、支付耗時比較長的情況，在此過程中，需要收款人員不斷調整掃碼槍的掃描角度，或者需要消費者不斷調整收款碼的顯示角度，降低了掃碼支付的效率，還降低了使用者使用體驗。 因此，需要提供一種能夠提高掃碼成功率、掃碼效率的圖形碼掃描方法及掃碼設備。At present, with the rapid development of mobile Internet technology, mobile payment has the characteristics of simple, convenient and convenient payment, making the application of mobile payment more and more popular and has become an indispensable part of people's daily life. For example, merchants use barcode scanners to scan and recognize the payment codes presented by consumers to complete mobile payments. Therefore, barcode scanners have become the main payment collection device for mobile payments in public places. However, in the existing process of scanning the payment code with a scanner, the angle between the scanner and the payment code is too large due to the height difference between the consumer and the payee, and the distance between the stations. When the code scanning fails and the payment takes a long time, during this process, the payee needs to continuously adjust the scanning angle of the code scanner, or the consumer needs to continuously adjust the display angle of the payment code, which reduces the efficiency of scanning code payment , It also reduces the user experience. Therefore, it is necessary to provide a graphic code scanning method and a code scanning device that can improve the success rate and efficiency of scanning codes.

為了使本技術領域的人員更好地理解本說明書一個或多個中的技術方案，下面將結合本說明書一個或多個實施例中的附圖，對本說明書一個或多個實施例中的技術方案進行清楚、完整地描述，顯然，所描述的實施例僅僅是本說明書一個或多個一部分實施例，而不是全部的實施例。基於本說明書一個或多個中的實施例，本領域普通技術人員在沒有作出進步性勞動前提下所獲得的所有其他實施例，都應當屬本說明書一個或多個保護的範圍。 本說明書一個或多個實施例提供了一種圖形碼掃描方法、掃碼支付方法及掃碼設備，在利用掃碼設備掃描圖形碼時，自動確定該掃碼設備中影像採集模組掃描待識別圖形碼的相對掃描角度，基於該相對掃描角度控制影像採集模組進行旋轉，達到將該相對掃描角度縮小到預設範圍內，再利用旋轉後的影像採集模組對待識別圖形碼進行掃描，這樣能夠提高影像採集模組獲取到的圖形碼成像的可識別度，進而提高圖形碼掃描的效率和成功率。 圖1為本說明書一個或多個實施例提供的圖形碼掃描方法的第一種流程示意圖，圖1中的方法應用於掃碼設備執行，如圖1所示，該方法至少包括以下步驟： S101，確定掃碼設備中影像採集模組掃描待識別圖形碼的相對掃描角度，其中，該相對掃描角度為影像採集模組的掃描方向與待識別圖形碼的垂線方向的夾角； 具體的，待識別圖形碼可以是條碼、二維條碼或其他圖形碼，影像採集模組可以是可旋轉的攝影鏡頭，在使用掃碼設備對圖形碼進行掃描時，由掃碼設備中控制模組自動確定影像採集模組的相對掃描角度。 S102，根據確定出的相對掃描角度，旋轉影像採集模組，以使旋轉後的影像採集模組的相對掃描角度小於預設臨限值； 具體的，在確定出相對掃描角度後，由控制模組判斷該相對掃描角度是否大於預設臨限值，若判斷結果為是，則說明掃碼設備與待識別圖形碼之間形成的角度偏差比較大，可能導致多次掃碼失敗、支付耗時比較長，因此，需要透過旋轉影像採集模組來調節影像採集模組的掃描方向，從而減小相對掃描角度，將該相對掃描角度縮小到預設範圍內，使得掃碼設備以近似垂直角度掃描待識別圖形碼； S103，利用旋轉後的影像採集模組，對待識別圖形碼進行掃描，具體的，透過旋轉影像採集模組使得影像採集模組的基準面(即影像採集平面)與待識別圖形碼所在平面近似平行後，由影像採集模組對待識別圖形碼進行掃描，並得到相應的掃描結果，將該掃描結果傳輸至掃碼設備中通信模組，由通信模組將該掃描結果傳輸至對應的終端設備，以觸發該終端設備進行相應的處理操作； 在一個具體實施例中，以掃碼支付的應用場景為例，終端設備在接收到掃碼設備傳輸的掃描結果後，根據該掃描結果執行支付處理操作，進而完成本次掃碼支付，這樣能夠縮短掃碼支付時間。 本說明書一個或多個實施例中，在利用掃碼設備掃描圖形碼時，自動確定該掃碼設備中影像採集模組掃描待識別圖形碼的相對掃描角度，基於該相對掃描角度控制影像採集模組進行旋轉，達到將該相對掃描角度縮小到預設範圍內，再利用旋轉後的影像採集模組對待識別圖形碼進行掃描，這樣能夠提高影像採集模組獲取到的圖形碼成像的可識別度，進而提高圖形碼掃描的效率和成功率。 進一步的，針對確定相對掃描角度的過程，結合三點確定一個平面的原理，可以透過在掃碼設備中設置至少三個發光光源，基於發光光源照射到待識別圖形碼上的至少三個光斑，來確定待識別圖形碼所在平面，進而確定相對掃描角度，基於此，如圖2所示，上述S101確定掃碼設備中影像採集模組掃描待識別圖形碼的相對掃描角度，具體包括： S1011，確定照射到待識別圖形碼的至少三個光斑的座標資訊； 具體的，掃碼設備中設置的至少三個發光光源分別向待識別圖形碼發射預設方向的光束，得到照射到待識別圖形碼的至少三個光斑，針對每個發光光源而言，該發光光源發射的光束的方向保持不變，在具體實施時，為了提高確定出的圖形碼所在平面的準確度，各發光光源的預設方向各不相同，這樣能夠增加至少三個光斑的分佈離散度，進而適當增大至少三個光斑所構成的平面圖形的實際面積； 以發光光源的數量等於3為例，每個發光光源的發射光束落到圖形碼上將形成一個光斑，這樣在圖形碼上形成三個光斑，可以預先以掃碼設備中的影像採集模組為參考物件建立三維座標系，確定影像採集模組的基準面，且影像採集模組的掃描方向垂直於該基準面，對應的，三個光斑的座標分別為

Figure 02_image021
，因此，可以確定出掃碼設備中影像採集模組掃描待識別圖形碼的相對掃描角度； 其中，參考線段垂直於影像採集模組的基準面，參考垂線垂直於圖形碼所在平面(即目標平面)，當時夾角θ =0時，參考垂線與參考線段重合，此時影像採集模組的基準面與圖形碼所在平面平行。 具體的，針對參考垂線的函數關係式的確定過程，上述S10131確定目標平面的參考垂線的函數關係式，具體包括： 步驟一，在圖形碼所在的目標平面上，確定至少三個光斑所構成的平面圖形，其中，當發光光源的數量等於3時，所構成的平面圖形為三邊形，當發光光源的數量等於4時，所構成的平面圖形為四邊形，依次類推，仍以發光光源的數量等於3為例，若三個光斑分別為點S1

For a clear and complete description, it is obvious that the described embodiments are only a part of one or more embodiments in this specification, rather than all the embodiments. Based on one or more embodiments in this specification, all other embodiments obtained by a person of ordinary skill in the art without making progressive work shall fall within the scope of one or more protections of this specification. One or more embodiments of this specification provide a graphic code scanning method, a code scanning payment method, and a code scanning device. When the graphic code is scanned by the code scanning device, it is automatically determined that the image acquisition module in the scanning device scans the image to be recognized. The relative scanning angle of the code, based on the relative scanning angle, the image acquisition module is controlled to rotate, so as to reduce the relative scanning angle to a preset range, and then use the rotated image acquisition module to scan the pattern code to be identified. Improve the recognizability of the graphic code imaging obtained by the image acquisition module, thereby improving the efficiency and success rate of graphic code scanning. Fig. 1 is a schematic diagram of the first flow chart of a graphic code scanning method provided by one or more embodiments of this specification. The method in Fig. 1 is applied to a code scanning device. As shown in Fig. 1, the method includes at least the following steps: S101 , Determine the relative scan angle of the image capture module in the code scanning device to scan the graphic code to be recognized, where the relative scan angle is the angle between the scan direction of the image capture module and the vertical direction of the graphic code to be recognized; specifically, to be recognized The graphic code can be a bar code, a two-dimensional bar code or other graphic codes. The image capture module can be a rotatable camera lens. When the graphic code is scanned by a code scanning device, the control module in the code scanning device automatically determines the image capture The relative scanning angle of the module. S102: Rotate the image acquisition module according to the determined relative scan angle, so that the relative scan angle of the rotated image acquisition module is smaller than a preset threshold; specifically, after the relative scan angle is determined, the control module The group judges whether the relative scanning angle is greater than the preset threshold. If the judgment result is yes, it means that the angle deviation between the scanning device and the graphic code to be recognized is relatively large, which may cause multiple scanning failures and time-consuming payment It is relatively long, so it is necessary to adjust the scanning direction of the image acquisition module by rotating the image acquisition module, thereby reducing the relative scanning angle, and reducing the relative scanning angle to a preset range, so that the scanning device scans at an approximate vertical angle Graphic code to be recognized; S103, using the rotated image capture module to scan the graphic code to be recognized. Specifically, the reference plane (ie image capture plane) of the image capture module and the graphic to be recognized are made by rotating the image capture module After the plane of the code is approximately parallel, the image acquisition module scans the pattern code to be identified, and obtains the corresponding scan result. The scan result is transmitted to the communication module of the code scanning device, and the communication module transmits the scan result to The corresponding terminal device triggers the terminal device to perform the corresponding processing operation; In a specific embodiment, taking the application scenario of scanning code payment as an example, the terminal device receives the scanning result transmitted by the scanning device according to the scanning As a result, the payment processing operation is executed, and then this scan code payment is completed, which can shorten the scan code payment time. In one or more embodiments of this specification, when a code scanning device is used to scan a graphic code, the relative scanning angle of the image capture module in the scanning device to scan the graphic code to be recognized is automatically determined, and the image capture module is controlled based on the relative scanning angle. The group rotates to reduce the relative scanning angle to the preset range, and then use the rotated image acquisition module to scan the pattern code to be identified, which can improve the recognizability of the pattern code imaging obtained by the image acquisition module , Thereby improving the efficiency and success rate of graphic code scanning. Further, for the process of determining the relative scanning angle, combining the principle of determining a plane with three points, at least three light-emitting light sources can be arranged in the code scanning device, based on the light-emitting light source irradiating at least three light spots on the pattern code to be recognized, To determine the plane of the graphic code to be recognized, and then determine the relative scanning angle. Based on this, as shown in Figure 2, the above S101 determines the relative scanning angle of the image acquisition module in the code scanning device to scan the graphic code to be recognized, which specifically includes: S1011, Determine the coordinate information of at least three light spots irradiated to the pattern code to be identified; specifically, the at least three light-emitting light sources provided in the code scanning device respectively emit light beams in a preset direction to the pattern code to be identified to obtain the pattern code to be identified For each light-emitting light source, the direction of the light beam emitted by the light-emitting source remains unchanged. In specific implementation, in order to improve the accuracy of the plane where the determined graphic code is located, the preset The directions are different, which can increase the dispersion of at least three light spots, thereby appropriately increasing the actual area of the plane figure formed by the at least three light spots; Taking the number of light-emitting sources equal to 3 as an example, the emission of each light-emitting source When the light beam falls on the graphic code, a light spot will be formed. In this way, three light spots are formed on the graphic code. The image acquisition module in the code scanning device can be used as a reference object to establish a three-dimensional coordinate system to determine the reference plane of the image acquisition module. And the scanning direction of the image acquisition module is perpendicular to the reference plane. Correspondingly, the coordinates of the three light spots are

At this time, the reference plane of the image acquisition module is parallel to the plane where the graphic code is located. For the determination process of the coordinate information of at least three light spots, as shown in FIG. 3, the above S1011 determines the coordinate information of at least three light spots irradiated to the pattern code to be identified, specifically including: S10111, determining that the pattern code to be identified is irradiated Specifically, when the code scanning device is assembled, the emission angles of the luminous beams of the at least three luminous light sources set in the code scanning device are recorded, and each luminous light source is correspondingly emitted The angle is stored in the control module. Under the preset reference coordinate system, the emission angles of the three light-emitting light sources are respectively θ 1 , θ 2 , and θ 3 ; S10112, determine the line segment lengths of at least three light spots from the image acquisition module; Specifically, because the laser has good directivity and needs to obtain the distance between the light-emitting point and the graphic code, the at least three light-emitting light sources provided in the code scanning device may be laser rangefinders through which the laser The rangefinder can obtain the distance between the luminous point of the laser emitted by itself and the graphic code, and then the distance from the image acquisition module to the light spot of each luminous light source falling on the graphic code. The luminous light source corresponds to each luminous light source obtained The distance data is transmitted to the control module, and the control module can obtain the line segment lengths of at least three light spots from the image acquisition module. Taking the number of light-emitting light sources equal to 3 as an example, the line segments corresponding to the light spots of the three light-emitting light sources The lengths are l 1 , l 2 , and l 3 respectively ; S10113, determine the coordinate information of at least three light spots according to the determined emission angle and line segment length of each light-emitting source; specifically, combine the polar coordinate system and the three-dimensional coordinate system According to the corresponding emission angle and line length of each light-emitting light source, the coordinate information of the light spot corresponding to each light-emitting light source can be obtained.

Therefore, it is possible to determine the relative scan angle of the image capture module in the code scanning device for scanning the graphic code to be recognized; where the reference line segment is perpendicular to the reference plane of the image capture module, and the reference vertical line is perpendicular to the plane where the graphic code is located (ie the target plane). ), when the included angle θ = 0, the reference vertical line coincides with the reference line segment, and the reference plane of the image acquisition module is parallel to the plane where the graphic code is located. Specifically, for the process of determining the function relational expression of the reference vertical line, the above S10131 determines the function relational expression of the reference vertical line of the target plane, which specifically includes: Step 1. On the target plane where the graphic code is located, determine at least three light spots. Plane graphics, where, when the number of light-emitting sources is equal to 3, the formed plane figure is a triangle; when the number of light-emitting sources is equal to 4, the formed plane figure is a quadrilateral, and so on, the number of light sources is still It is equal to 3 as an example, if the three light spots are point S1

Correspondingly, the intersection point of the reference vertical line and the target plane is The center point of the plane figure, that is, the intersection point O of the above plane perpendiculars is the center point of the plane figure; among them, after the reference perpendicular of the target plane is selected, according to the function expression of the target plane, the reference perpendicular in the same three-dimensional coordinate system can be determined Functional relation

. Specifically, for the process of determining the relative scan angle based on the functional relationship of the reference perpendicular and the intersection of the plane perpendicular, the above S10133 determines the image acquisition mode in the code scanning device according to the determined functional relationship of the reference perpendicular and the coordinate information of the intersection of the plane perpendicular. The relative scanning angles of the pattern code to be identified for group scanning include: Step 1. Determine the length of the first line segment between the image acquisition module and the reference perpendicular according to the determined function relationship of the reference vertical. Specifically, determine the image acquisition mode The length of the first line segment between the vertical point on the base plane of the group and the reference vertical; Step 2, according to the determined coordinate information of the intersection point of the plane vertical line, determine the second line segment length between the image acquisition module and the intersection point of the plane vertical line, specifically, Determine the length of the second line segment between the vertical point on the reference plane of the image capture module and the intersection of the vertical line of the plane; Step 3: Determine the scan of the image capture module in the code scanning device according to the determined length of the first line segment and the second line segment The relative scanning angle of the pattern code to be recognized. In specific implementation, as shown in Figure 5, the coordinate point P represents the coordinate of the vertical point on the reference plane of the image acquisition module, which is
Figure 02_image015

Figure 02_image018
, The length of the first line segment is the distance from the coordinate point P to the coordinate point M, that is, the length of the line segment PM is c , and the length of the second line segment is the distance from the coordinate point P to the coordinate point O, that is, the length of the line segment PO is a , corresponding , The angle θ between the line segment OP and the line segment OM is the relative scanning angle at which the image acquisition module in the code scanning device scans the graphic code to be recognized. Specifically, as shown in Fig. 6a, a side view of the code scanner when scanning the graphic code before rotating the image capture module is shown. In Fig. 6a, the scanning direction of the image capture module and the image code to be identified are shown. The angle between the vertical direction (that is, the plane normal direction) is θ . Taking the number of light-emitting light sources equal to 3 as an example, the code scanning device includes an image acquisition module, and the code scanning device is also provided with three light-emitting light sources. The emission angles of the luminous beams of the luminous light sources are different. The luminous beam emitted by each luminous source will fall on a spot on the pattern code, and the plane information of the pattern code can be determined according to the three spots irradiated on the pattern code. Furthermore, in combination with the above-mentioned process of determining the included angle between the reference vertical line and the reference line segment, the relative scanning angle of the image collection module scanning the graphic code to be recognized is determined. As shown in Figure 6b, after rotating the image acquisition module, the side view of the code scanner when scanning the graphic code is given. After determining the relative scanning angle of the image acquisition module scanning the graphic code to be recognized, the scanning The control module in the code device controls the rotation angle θ of the drive module to the image acquisition module. In Figure 6b, the angle between the scanning direction of the image acquisition module and the vertical direction of the pattern code to be identified (ie, the plane normal direction) is θ = 0, making the reference plane of the image acquisition module parallel to the plane where the graphic code to be identified is located.
