Description

用于终端设备的二维码生成方法和装置
本专利申请要求于2018年6月22日提交的、申请号为201810653369.0、申请人为北京京东尚科信息技术有限公司和北京京东世纪贸易有限公司、发明名称为“用于终端设备的二维码生成方法和装置”的中国专利申请的优先权，该申请的全文以引用的方式并入本申请中。
技术领域
本申请实施例涉及计算机技术领域，具体涉及用于终端设备的二维码生成方法和装置。
背景技术
随着信息处理技术的发展，二维码以其编码范围广等特点得到了广泛的应用。二维码通常是在二维平面上按照一定的规律排列的黑白相间的色块，且色块可以为正方形、三角形等几何图形。当然，二维码中的色块还可以为深浅不同的其它颜色，例如彩色。
目前，电子设备上显示的二维码一般为静态的黑白图片或者是中间包含一个静态图标的黑白图片。现有的二维码通常没有背景图像，或者背景图像一成不变。由于二维码在截图后还是有效的，因此用户很难辨认出待扫描的二维码(没有背景图像的二维码或者背景图像一成不变的二维码)是否为截图、拍照等而成的二维码。在某些特殊的场景下，例如支付或身份验证等，截图等形成的二维码会给人留下作弊的空间。
发明内容

图1示出了可以应用本申请的用于终端设备的二维码生成方法或用于终端设备的二维码生成装置的实施例的示例性系统架构100。
如图1所示，系统架构100可以包括终端设备101、102、103，网络104和服务器105。网络104用以在终端设备101、102、103和服务器105之间提供通信链路的介质。网络104可以包括各种连接类型，例如有线、无线通信链路或者光纤电缆等等。

终端设备101、102、103可以是具有显示屏并且支持图像采集和二维码显示的各种电子设备，包括但不限于智能手机、平板电脑、电子书阅读器、膝上型便携计算机和台式计算机等等。
可以理解的是，终端设备101、102、103可以不仅支持图像采集和二维码显示，终端设备101、102、103还可以对得到的摄像头实时拍摄画面和二维码信息等进行分析处理得到二维码。此时，本申请实施例所提供的用于终端设备的二维码生成方法可以由终端设备101、102、103执行。相应地，用于终端设备的二维码生成装置也可以设置于终端设备101、102、103中。此时，系统架构100中可以不需要设置服务器105和网络104。

应该理解，图1中的终端设备、网络和服务器的数目仅仅是示意性的。根据实现需要，可以具有任意数目的终端设备、网络和服务器。
继续参考图2，示出了根据本申请的用于终端设备的二维码生成方法的一个实施例的流程200。该用于终端设备的二维码生成方法，包括以下步骤：
步骤201，接收用户输入的二维码生成指令。
在本实施例中，用户在使用终端设备进行付款或身份验证等的情况下，用户可以通过点击或触控等操作向终端设备输入二维码生成指令。用于终端设备的二维码生成方法的执行主体(例如图1所示的终端设备101、102、103)可以接收用户输入的二维码生成指令。其中，上述二维码生成指令可以包括用于生成二维码的二维码信息。通常，二维码信息可以包括文字、数字、字母、图像、声音等数据信息。
步骤202，启动摄像头，生成摄像头实时拍摄画面。
在本实施例中，终端设备可以配置有摄像头。例如，手机终端的前置摄像头或后置摄像头等。响应于步骤201接收到二维码生成指令，上述执行主体(例如图1所示的终端设备101、102、103)可以启动终端设备上所安装的摄像头。摄像头被启动以后可以实时地对周围环境进行拍摄，从而生成摄像头实时拍摄画面。可以理解的是，所生成的摄像头实时拍摄画面可以显示在终端设备上。作为示例，终端设备可 以为手机，手机上的摄像头启动之后可以在手机的显示屏上实时显示摄像头拍摄到的画面。可以理解的是，对摄像头拍摄到的实时拍摄画面可以不进行存储。
步骤203，基于二维码信息和所生成的摄像头实时拍摄画面，生成显示有二维码的实时画面。
在本实施例中，在接收到二维码生成指令中的二维码信息和摄像头采集生成的摄像头实时拍摄画面之后，上述执行主体可以基于二维码信息和摄像头实时拍摄画面生成显示有二维码的实时画面。作为示例，上述执行主体可以将二维码信息进行一系列的转换，在摄像头实时拍摄画面上将二维码信息转换成存储有二维码信息的二维码图形。可以理解的是，摄像头启动之后可以对周围环境进行实时地拍摄，从而使得终端设备的界面上可以显示摄像头拍摄的当前帧画面，该当前帧画面即为摄像头实时拍摄画面。将二维码信息转换而成的二维码显示在由摄像头拍摄得到的当前帧画面中，从而生成显示有二维码的实时画面。
在本实施的一些可选的实现方式中，上述执行主体可以将二维码信息直接在生成的摄像头实时拍摄画面中转换成二维码图形，从而生成显示有二维码的实时画面。或者，上述执行主体还可以对摄像头采集生成的摄像头实时拍摄画面进行图像处理，而后将二维码信息在处理后的摄像头实时拍摄画面中转换成二维码图形。
与现有技术中的无背景图像的静态二维码和有背景图像的静态二维码相比，利用本申请实施例提供的方法所生成的二维码，该二维码的背景图像为用户所在终端设备利用摄像头对周围环境拍摄得到的实时画面，从而使得扫码方(对生成的二维码进行扫描的一方)可以从所生成的二维码的背景图像判断出终端设备上所显示的二维码是否为原始生成的二维码，避免了二维码被截图或拍照造成信息泄露，提高了二维码的安全性。
在本实施例的一些可选的实现方式中，上述执行主体在生成显示有二维码的实时画面之后，扫码方可以对生成的二维码进行扫描。当扫码方对生成的二维码扫描完成后，接收用户输入的二维码关闭指令， 以便于上述执行主体可以关闭摄像头。
在本实施例的一些可选的实现方式中，当扫码方对生成的二维码扫描完成后，上述执行主体可以直接生成二维码的关闭指令，关闭已经启动的摄像头。
在本实施例的一些可选的实现方式中，在上述执行主体生成并显示的二维码实时画面中，二维码图形的尺寸可以与摄像头实时拍摄画面的尺寸相同。或者，二维码图形的尺寸可以小于摄像头实时拍摄画面的尺寸，且二维码图像可以位于摄像头实时拍摄画面的中间位置或任意角落位置。
通常，将二维码信息转换为二维码图形可以包括多个步骤。首先，把二维码信息中的原始数据按照一定的模式编码为一系列的字符串，如按照二进制编码将原始数据构成由0和1构成的二进制字符串，而后根据1代表深色块、0代表浅色块这一原则将二进制字符串进一步转化为一个色块列，最后遵循特定的规则将该色块序列填入一个方形矩阵，从而形成二维码。一般情况下，生成的二维码中色块之间是不存在缝隙的，因此现有的二维码生成之后，用户无法透过二维码看到二维码的背景图像。本申请的上述实施例提供的方法，可以预先设置第一预设阈值，上述执行主体可以控制所生成的二维码的相邻色块之间的距离为第一预设阈值。因此，通过设置第一预设阈值，可以使得生成的二维码中相邻色块之间留出一定的缝隙，用户通过缝隙可以更方便地看到二维码的背景，从而更容易地辨别出用户出示的二维码是否为截图等，进一步提高了二维码的安全性。
继续参见图3，图3是根据本实施例的用于终端设备的二维码生成方法的应用场景的一个示意图。在图3的应用场景中，手机可以接收用户输入的二维码生成指令，该二维码生成指令中可以包括二维码信息。而后，启动手机的前置摄像头301(或后置摄像头)，以便于手机的前置摄像头可以实时拍摄周围环境，从而生成摄像头实时拍摄画面，如图3所示的用户头像。可以理解的是，这里可以利用手机中的“相机”应用软件来启动上述摄像头。最后，基于二维码信息和摄像头实时拍摄画面，可以在手机上生成并显示叠加二维码的实时画面 302，如图3所示。该叠加二维码的实时画面可以包括由二维码信息转换而来的二维码图形和作为动态的背景图像的摄像头实时拍摄画面，并且叠加二维码的实时画面可以显示在“相机”应用软件所打开的界面上。
本申请实施例提供的用于终端设备的二维码生成方法和装置，可以接收用户输入的二维码生成指令，而后可以启动摄像头生成摄像头实时拍摄画面，最后基于二维码信息和所生成的摄像头实时拍摄画面可以生成显示有二维码的实时画面，从而使得扫码方可以辨别用户出示的二维码是否为原始生成的二维码，提高了二维码的安全性。
进一步参考图4，其示出了用于终端设备的二维码生成方法的另一个实施例的流程400。该用于终端设备的二维码生成方法的流程400，包括以下步骤：
步骤401，接收用户输入的二维码生成指令。
在本实施例中，用户在使用终端设备进行付款或身份验证等情况下，用户可以通过点击或触控等操作向终端设备输入二维码生成指令。用于终端设备的二维码生成方法的执行主体(例如图1所示的终端设备101、102、103)可以接收用户输入的二维码生成指令。其中，上述二维码生成指令可以包括用于生成二维码的二维码信息。通常，二维码信息可以包括文字、数字、字母、图像、声音等数据信息。
步骤402，启动摄像头，生成摄像头实时拍摄画面。
在本实施例中，终端设备可以配置有摄像头。例如，手机终端的前置摄像头或后置摄像头等。基于步骤201接收到的二维码生成指令，上述执行主体(例如图1所示的终端设备101、102、103)可以启动终端设备上所安装的摄像头。摄像头启动以后可以实时地对周围环境进行拍摄，从而得到生成的摄像头实时拍摄画面。可以理解的是，所生成的摄像头实时拍摄画面可以显示在终端设备上。作为示例，终端设备可以为手机，手机上的摄像头启动之后可以在手机的显示屏上实时显示摄像头拍摄到的画面。可以理解的是，对摄像头拍摄到的实时拍摄画面可以不进行存储，例如，该摄像头实时拍摄画面可以为手机中打开“相机”应用的界面所展示的画面，而不需要对界面中所展示的 画面进行拍照存储。
步骤403，对摄像头实时拍摄画面进行模糊处理。
在本实施例中，基于步骤402生成的摄像头实时拍摄画面，上述执行主体可以利用直接卷积法、基于卷积定理的FFT(fast Fourier transform，快速傅立叶变换)方法和积分图方法等各种方式对所生成的摄像头实时拍摄画面进行模糊处理。
作为示例，可以采用对摄像头实时拍摄画面进行缩小后再进行卷积运算的方式得到模糊处理后的图片。具体地，首先可以选择合适的缩放因子来将生成的摄像头实时拍摄画面缩小；而后将滤波模板和缩小后的摄像头实时拍摄画面进行卷积运算以使缩小后的摄像头实时拍摄画面模糊；最后可以对缩小的模糊图像通过线性插值运算进行放大，从而可以得到一张和原图大小相同的模糊的摄像头实时拍摄画面。
步骤404，将二维码信息转换成二维码，在模糊处理后的摄像头实时拍摄画面中显示生成的二维码。
在本实施中，基于步骤403得到的模糊处理后的摄像头实时拍摄画面，上述执行主体可以将二维码信息转换成二维码图形，并在模糊处理后的摄像头实时拍摄画面中显示转换成的二维码。将摄像头实时拍摄画面模糊化处理后再在其上生成二维码图形，可以提高所生成的二维码的扫码成功率。
作为示例，所生成的二维码图像可以为黑色块和白色块组成，摄像头实时拍摄画面中也有可能会存在与二维码中的黑色块和白色块形状相同或相似的黑色块或白色块，这种色块的存在可能会导致在未经处理的摄像头实时拍摄画面中生成的二维码被扫码失败。但是，将摄像头实时拍摄画面进行模糊化处理后，可以降低将其中的、与二维码中的黑色块和白色块形状相同或相似的黑色块或白色块判断成生成的二维码中的一部分的概率，从而提高了所生成的二维码被扫码成功的概率。
在本实施的一些可选的实现方式中，基于二维码信息，生成显示有二维码的实时画面还可以包括：设置二维码的目标容错率，其中，目标容错率大于第二预设阈值；以目标容错率将二维码信息转变换成 二维码，在所生成的摄像头实时拍摄画面中显示生成的二维码。具体地，上述执行主体在启动摄像头生成摄像头实时拍摄画面之后，可以为待生成的二维码设置目标容错率，并通过限定该目标容错率大于第二预设阈值来保证该目标容错率可以为一个较大的值；而后，上述执行主体可以基于上述目标容错率将二维码信息转换成二维码，并在所生成的摄像头实时拍摄画面中显示所生成的二维码。该方法同样地可以提高所生成的二维码的扫码成功率。二维码的容错率，也可以称为二维码的纠错率，通常可以表征二维码被遮挡后仍可以被扫描出来的能力。一般情况下，容错率越高，二维码图形中可被遮挡的部分可以越多。
在本实施的一些可选的实现方式中，基于二维码信息，生成显示有二维码的实时画面还可以包括：设置二维码的目标容错率，其中，目标容错率大于第二预设阈值；基于目标容错率将二维码信息转变换成二维码，在模糊处理后的摄像头实时拍摄画面中显示生成的二维码。
从图4中可以看出，与图2对应的实施例相比，本实施例中的用于终端设备的二维码生成方法的流程400突出了基于二维码信息和所生成的摄像头实时拍摄画面，生成显示有二维码的实时画面的步骤。由此，本实施例描述的方案在提高了二维码的安全性的同时，可以提高二维码被扫描成功的概率。
进一步参考图5，作为对上述各图所示方法的实现，本申请提供了一种用于终端设备的二维码生成装置的一个实施例，该装置实施例与图2所示的方法实施例相对应，该装置具体可以应用于各种电子设备中。
如图5所示，本实施例的用于终端设备的二维码生成装置500包括：接收单元501、拍摄画面生成单元502和二维码画面生成单元503。该终端设备可以包括摄像头。其中，接收单元501被配置成接收用户输入的二维码生成指令，其中，二维码生成指令包括二维码信息；拍摄画面生成单元502被配置成启动摄像头，生成摄像头实时拍摄画面；二维码画面生成单元503被配置成基于二维码信息和所生成的摄像头实时拍摄画面，生成显示有二维码的实时画面。
本申请的上述实施例提供的用于终端设备的二维码生成装置500，接收单元501可以接收用户输入的二维码生成指令，而后拍摄画面生成单元502可以启动摄像头生成摄像头实时拍摄画面，最后二维码画面生成单元503基于二维码信息和所生成的摄像头实时拍摄画面可与生成显示有二维码的实时画面，从而使得用户可以辨别生成的二维码是否为二维码截图，提高了二维码信息的安全性。
在本实施例的一些可选的实现方式中，二维码画面生成单元503进一步被配置成：对摄像头实时拍摄画面进行模糊处理；将二维码信息转换成二维码，在模糊处理后的摄像头实时拍摄画面中显示生成的二维码。
在本实施例的一些可选的实现方式中，二维码画面生成单元503进一步被还配置成：将二维码信息转换成二维码，在所生成的摄像头实时拍摄画面中显示生成的二维码。
在本实施例的一些可选的实现方式中，装置500还包括：设置单元，被配置成将二维码中相邻的色块之间的距离值设置为第一预设阈值。

可以以一种或多种程序设计语言或其组合来编写用于执行本申请的操作的计算机程序代码，所述程序设计语言包括面向对象的程序设计语言—诸如Java、Smalltalk、C++，还包括常规的过程式程序设计语言—诸如“C”语言或类似的程序设计语言。程序代码可以完全地在用户计算机上执行、部分地在用户计算机上执行、作为一个独立的软件包执行、部分在用户计算机上部分在远程计算机上执行、或者完全在远程计算机或服务器上执行。在涉及远程计算机的情形中，远程计算机可以通过任意种类的网络——包括局域网(LAN)或广域网(WAN)—连接到用户计算机，或者，可以连接到外部计算机(例如利用因特网服务提供商来通过因特网连接)。
附图中的流程图和框图，图示了按照本申请各种实施例的系统、方法和计算机程序产品的可能实现的体系架构、功能和操作。在这点上，流程图或框图中的每个方框可以代表一个模块、程序段、或代码的一部分，该模块、程序段、或代码的一部分包含一个或多个用于实现规定的逻辑功能的可执行指令。也应当注意，在有些作为替换的实现中，方框中所标注的功能也可以以不同于附图中所标注的顺序发生。例如，两个接连地表示的方框实际上可以基本并行地执行，它们有时也可以按相反的顺序执行，这依所涉及的功能而定。也要注意的是，框图和/或流程图中的每个方框、以及框图和/或流程图中的方框的组合，可以用执行规定的功能或操作的专用的基于硬件的系统来实现，或者可以用专用硬件与计算机指令的组合来实现。
描述于本申请实施例中所涉及到的单元可以通过软件的方式实 现，也可以通过硬件的方式来实现。所描述的单元也可以设置在处理器中，例如，可以描述为：一种处理器包括接收单元、拍摄画面生成单元、二维码画面生成单元。其中，这些单元的名称在某种情况下并不构成对该单元本身的限定，例如，接收单元还可以被描述为“接收用户输入的二维码生成指令的单元”。
作为另一方面，本申请还提供了一种计算机可读介质，该计算机可读介质可以是上述实施例中描述的装置中所包含的；也可以是单独存在，而未装配入该装置中。上述计算机可读介质承载有一个或者多个程序，当上述一个或者多个程序被该装置执行时，使得该装置：接收用户输入的二维码生成指令，其中，二维码生成指令包括二维码信息；启动摄像头，生成摄像头实时拍摄画面；基于二维码信息和所生成的摄像头实时拍摄画面，生成显示有二维码的实时画面。
以上描述仅为本申请的较佳实施例以及对所运用技术原理的说明。本领域技术人员应当理解，本申请中所涉及的发明范围，并不限于上述技术特征的特定组合而成的技术方案，同时也应涵盖在不脱离上述发明构思的情况下，由上述技术特征或其等同特征进行任意组合而形成的其它技术方案。例如上述特征与本申请中公开的(但不限于)具有类似功能的技术特征进行互相替换而形成的技术方案。
