Description

识别图形码的方法及电子设备
本申请要求于2022年06月07日提交国家知识产权局、申请号为202210639518.4、申请名称为“一种拍摄方法及终端”的中国专利申请和2022年09月05日提交国家知识产权局、申请号为202211080988.8、申请名称为“识别图形码的方法及电子设备”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及终端技术领域，尤其涉及一种识别图形码的方法及电子设备。
背景技术
目前，识别图形码，即“扫码”，已经成为生活中一种常见的场景，极大地提高了信息的传播和互换的效率，具有非常重要的社会功能。例如，商户可以发布收款码，包括将印有收款码的纸张张贴在现实世界的任意位置或将收款码图像在任意电子的显示屏上进行显示，顾客通过另一电子设备扫码就可以向商户进行支付，实现跨时空交易。
现有技术中，电子设备包括多种不同的应用，每个应用可以识别一种图形码。用户先根据待识别的图形码，在电子设备上手动打开与该图形码对应的应用，通过该应用识别该图形码，使用起来体验感有限。
发明内容
有鉴于此，本申请提供一种识别图形码的方法及电子设备，能够在较低功耗的情况下，提高识别图形码的效率，并降低识别图形码的成本。
为了实现上述目的，第一方面，本申请实施例提供一种识别图形码的方法，应用于电子设备，所述方法包括：
当所述电子设备处于特定状态时，获取第一图像；
当所述第一图像包括第一图形码时，获取第二图像，所述第二图像包括第二图形码，其中，获取所述第一图像所产生的功耗，小于获取所述第二图像所产生的功耗，所述第一图像的图像质量低于所述第二图像的图像质量，所述第一图形码的图像质量低于所述第二图形码的图像质量；
确定所述第二图形码所承载的第一码信息以及所述第二图形码对应的第一应用；
当接收到确认操作时，通过所述第一应用显示与所述第一码信息对应的显示界面。
在本申请实施例中，电子设备可以在处于特定状态时，先在功耗较低的情况下通过第一摄像头获取图像质量较低的第一图像，并在第一图像包括第一图形码的情况下，在功耗较高的情况下通过第二摄像头获取图像质量较高的第二图像，从第二图像中识别第二图形码所承载的第一码信息以及第一应用，再向用户发出第一提示信息，使得用户感知到识别到第二图形码。在接收到用户的确认操作时，可以基于第一应用显示与第一码信息对应的显示界面。由于不需要用户查找第一应用，也不需要从第一应用 中查找图形码识别功能，因此极大地提高了识别图形码的效率，同时第一应用的开发人员也不要专门针对识别图形码这一功能进行软件布局和用户引导，降低了识别图形码的成本。且由于是先在功耗较低的情况下通过第一摄像头获取图像质量较低的第一图像，并在初步判断第一图像包括第一图形码的情况下，再次在功耗较高的情况下通过第二摄像头获取图像质量较高的第二图像，也能够减少电子设备识别图形码的功耗。
其中，由于电子设备是在确定通过第一摄像头获取的第一图像包括第一图形码时，通过第二摄像头获取第二图像，获取第二图像和第一图像之间的时间间隔很小，比如可以为毫秒级甚至是微秒级，因此，第二图像包括的图像内容和第一图像包括的图像内容可以相同或相似，且第一图像的图像质量可以高于第二图像的图像质量，第一图形码和第二图形码可以相同或相似，且第二图形码的图像质量高于第一图形码的图像质量。在一些实施例中，第二图像的分辨率可以高于第一图像的分辨率，第二图形码的分辨率可以高于第一图形码的分辨率。
在一些实施例中，特定状态可以是由用户或者相关技术人员事先设置的。在一些实施例中，可以是由电子设备通过对用户多次主动识别图形码的行为进行学习得到的。
可以理解是，电子设备可以同时确定第二图形码所承载的第一码信息以及第二图形码对应的第一应用，也可以先确定其中一个，再确定另一个。在一些实施例中，若电子设备先确定第二图形码对应的第一应用，则可以通过第一应用确定第二图形码所承载的第一码信息，从而提高确定第一码信息的准确性。在一些实施例中，若电子设备先确定第二图形码承载的第一码信息，则可以通过第一码信息确定第一应用，从而提高第一应用的准确性。
在一些实施例中，确认操作可以包括对电子设备某一表面(比如背面或显示屏)的敲击操作。在一些实施例中，确认操作可以包括对特定按键(包括实体按键或虚拟按键)的按键操作。
在一些实施例中，所述获取第一图像，包括：
通过第一摄像头，在第一拍摄模式下获取所述第一图像；
所述获取第二图像，包括：
通过所述第一摄像头，在第二拍摄模式下获取所述第一图像；
其中，所述第一拍摄模式为低分辨率模式，所述第二拍摄模式为高分辨率模式。
也即是，电子设备可以通过切换同一摄像头的低分辨率模式和高分辨模式，从而实现在低功耗情况下获取第一图像，在高功耗情况下获取第二图像，减少了对电子设备包括的摄像头数目的需求。
在一些实施例中，所述获取第一图像，包括：
通过第一摄像头获取所述第一图像；
所述获取第二图像，包括：
通过第二摄像头获取所述第一图像；
其中，所述第一摄像头为低功耗摄像头，所述第二摄像头为高功耗摄像头。
也即是，电子设备可以通过切换低功耗摄像头和高功耗摄像头，从而实现在低功耗情况下获取第一图像，在高功耗情况下获取第二图像，减少了对单一摄像头性能的需求。
在一些实施例中，当通过第一摄像头获取第一图像时，第一摄像头可以处于开启状态，第二摄像头等其他摄像头可以处于关闭状态；在一些实施例中，当通过第二摄像头获取第二图像时，第二摄像头可以处于开启状态，第一摄像头等其他摄像头可以处于关闭状态。
在一些实施例中，所述方法包括：
若所述第二图像中包括与所述第二图形码对应的场景特征，则确定所述第一图像中包括所述第二图形码；或，
若所述第二图像中包括与所述第二图形码对应的编码特征，则确定所述第一图像中包括所述第二图形码；或，

在一些实施例中，本申请所提供的识别图形码的方法，可以由应用程序中的应用程序(包括第三方应用程序或者系统应用程序)实现，或者可以由应用程序框架层或系统库中的系统服务实现。
为了便于理解本申请实施例中的技术方案，下面首先对本申请实施例的应用场景予以介绍。
应用程序层包括的某些应用可以识别与该应用对应的图形码。其中，图形码可以包括条形码、二维码等。比如，钱包等用于支付的应用可以识别收款码，从而向收款码所指示的收款方收款；电子码应用可以识别设置在各场所的场所码，从而记录用户到达该场所的场所名称以及到达时间等信息。
在一些实施例中，应用的开发人员需要在该应用中设置“扫一扫”功能，向用户说明该应用以及该“扫一扫”的功能、该“扫一扫”功能在该应用中的具体位置，使得用户知道通过该应用识别哪些图形码，在遇到这些图形码并打开该应用时，从该应用的哪个位置查找到该“扫一扫”功能，进而通过该“扫一扫”功能识别该图形码。在一些实施例中，用户可以将该应用的“扫一扫”功能的快捷方式添加到电子设备的桌面上，从而省去用户打开该应用并在该应用中查找“扫一扫”功能的操作，但用户仍然需要在确定待识别的图形码是与该应用对应的图形码，再通过该快捷方式，打开该“扫一扫”功能对该图形码进行识别。可以看出，在上述方式中，需要用户根据待识别的图形码，手动选择对应的应用，再从应用中选择相应的识别功能，才能够识别图形码。一方面，操作比较繁琐，识别图形码的效率低下；另一方面，用户需要熟悉图形码以及相关的应用，该应用的开发人员也需要专门对识别图形码这一功能进行布局和引导，提高了识别图形码的成本。
为解决上述至少部分技术问题，本申请实施例提供了一种识别图形码的方法。在本申请实施例中，电子设备可以在处于特定状态时，就可以通过第二摄像头获取第二图像，从第二图像中识别第二图形码所承载的第一码信息以及第一应用，再向用户发出第一提示信息，使得用户感知到识别到第二图形码。在接收到用户的确认操作时，可以基于第一应用显示与第一码信息对应的显示界面。由于不需要用户查找第一应用，也不需要从第一应用中查找图形码识别功能，因此极大地提高了识别图形码的效率，同时第一应用的开发人员也不要专门针对识别图形码这一功能进行软件布局和用户引导，降低了识别图形码的成本。由于不需要用户查找第一应用，也不需要从第一应用 中查找图形码识别功能，因此极大地提高了识别图形码的效率，同时第一应用的开发人员也不要专门针对识别图形码这一功能进行软件布局和用户引导，降低了识别图形码的成本。

在一些实施例中，第二提示信息可以包括第二图像、每个图形码对应的标记以及 每个图形码对应的应用图标。例如，如图24所示，第二提示信息包括图像B 1900、与二维码A 1901对应的标记1905、与二维码B 1902对应的标记1906、与二维码A 1901对应的应用标识1501以及与二维码B 1902对应的应用标识1904。用户可以通过点击与二维码A 1901对应的标记1905或者与二维码A 1901对应的应用标识1501，从而将二维码A 1901确定为第二图形码。或者用户可以点击与二维码B 1902对应的标记1906或者与二维码B 1902对应的应用标识1904，将二维码B 1902确定为第二图形码。
当然，在实际应用中，电子设备也可以通过其他方式来发出第二提示信息，第二提示信息也可以包括更多或更少的信息。
S1805，电子设备通过第一应用显示与第一码信息对应的显示界面。
其中，电子设备执行S1805的方式，可以参见前述S305中的相关描述。
在本申请实施例中，电子设备可以识别第二图像中包括的多个图形码以及各图形码对应的应用，并在其中确定第二图形码和第一应用，进一步提高了识别图形码的效率。另外，电子设备可以通过显示第二提示信息，接收用户在多个图形码以及应用中确定第二图形码和第一应用，进一步提高了第二图形码和第一应用的准确性。
请参照图25，为本申请实施例所提供的一种识别图形码的方法的流程图。其中，本申请是对图3所示的方法的具体描述，在第二图形码承载的第一码信息的信息类型包括URL时，电子设备可以提前基于第一码信息获取与第一码信息对应的数据。需要说明的是，该方法并不以图25以及以下所述的具体顺序为限制，应当理解，在其它实施例中，该方法其中部分步骤的顺序可以根据实际需要相互交换，或者其中的部分步骤也可以省略或删除。该方法包括如下步骤：
S301，当电子设备处于特定状态时，通过第二摄像头获取第二图像。
在一些实施例中，当通过第二摄像头获取第二图像时，第二摄像头可以处于开启状态，第一摄像头等其他摄像头可以处于关闭状态。
S302，电子设备确定第二图像中包括第二图形码。
S303，电子设备基于第二图像，确定第二图形码所承载的第一码信息以及第二图形码对应的第一应用。
其中，第一码信息的信息类型包括URL。
S306，电子设备从服务器获取第一码信息对应的数据。
当第一码信息的信息类型包括URL时，电子设备可以基于第一码信息从服务器获取与第一码信息对应的数据，以提前获取第一码信息对应的数据的时机。
在一些实施例中，电子设备可以基于第一码信息，从与第一应用对应的服务器，获取与第一码信息对应的数据。
S304，电子设备发出第一提示信息，第一提示信息用于提示检测到第二图形码。
S305，当电子设备接收到确认操作时，电子设备通过第一应用显示与第一码信息对应的显示界面。
电子设备可以通过第一应用加载第一码信息对应的数据，从而显示与第一码信息对应的显示界面。
需要说明的是，电子设备执行上述S301-S305的方式，也可以参照前述图3中的相关描述。
在本申请实施例中，电子设备在对用户进行提示之前，已经获取到了第一码信息对应的数据，因此当电子设备接收到确认操作时，可以不必再次获取该数据，而是可以快速地基于已经获取到数据，显示该显示界面，从而提高显示该显示界面的效率。
需要说明的是，电子设备也可以在确定第一码信息之后、显示与第一码信息对应的显示界面之前的其他时机，提前从服务器获取第一码信息对应的数据。
在一些实施例中，作为对图10所示的方法的具体描述，电子设备可以执行S1001-S1003来确定第二图形码所承载的第一码信息，并在第一码信息的信息类型包括URL时，提前从服务器获取第一码信息对应的数据，再执行S1004和S1005，并在S1005中通过第一应用加载该数据，以显示第一码信息对应的显示界面。
请参照图26，为本申请实施例所提供的一种对识别图形码的配置界面的示意图。以下将结合该配置界面，以通过系统应用实现识别图形码为例，对本申请实施例提供的配置识别图形码的方式进行说明。
用户可以从电子设备的系统设置中查找到智能扫码选项，用户点击该智能扫码选项，电子设备显示如图26所示的配置界面。
该配置界面包括智能扫码的场景示意图2601以及场景说明信息2602，用户可以通过场景示意图2601以及场景说明信息2602，了解智能扫码功能的使用方式和使用场景。
该配置界面包括智能扫码开关2603，用户可以通过点击智能扫码开关2603，选择启用或关闭智能扫码功能。比如当前该智能扫码开关2603为开状态，即表示打开了智能扫码功能。
该配置界面包括支付选项2604，该支付选项2604可以用于配置优先用于支付款项的应用。该配置界面还包括与支付选项2604对应的支付介绍信息2605，该支付介绍信息2605包括“当识别到收款码时，将优先使用默认支付方式进行支付”。用户通过该支付介绍信息2605即可确定，可以通过支付选项2604设置优先用于支付款项的应用，电子设备在识别到收款码时，将优先通过该应用(比如当前显示的钱包应用)，进行支付。
在一些实施例中，电子设备可以在确定一个用于支付的图形码对应多个用于快支付应用时，优先通过支付选项2604所配置的应用进行支付。例如，图形码A为用于支付的图形码，电子设备识别到与图形码A对应的应用包括快支付应用、信用卡应用和钱包应用等三个应用，支付选项2604所配置的应用为钱包应用，因此，电子设备可以通过钱包应用加载图形码A所承载的码信息来进入支付界面。
在一些实施例中，电子设备可以在识别到多个用于支付的图形码，每个图形码对应一个用于支付的应用时，优先通过支付选项2604所配置的应用以及该应用对应的图形码进行支付。例如，电子设备识别到图形码B和图形码C，图形码B和图形码C均为用于支付的图形码，与图形码B对应的应用为快支付应用，与图形码C对应的应用为钱包应用，且支付选项2604所配置的应用为钱包应用，因此，电子设备可以通过钱包应用加载图形码C所承载的码信息来进入支付界面。
需要说明的是，图26并不对配置界面构成限定，在实际应用中，该配置界面也可以包括更多或更少的配置选项。比如，该配制界面还可以包括触发方式配置项，用户 可以通过该触发方式配置项，对触发智能扫码的特定状态进行配置。又比如，该配置界面还可以包括针对码信息与应用之间的对应关系、信息类型与应用之间的对应关系、场景特征与应用之间的对应关系等至少一种对应关系进行配置的选项。
请参照图27，为本申请实施例所提供的一种识别图形码的方法的流程图。需要说明的是，该方法并不以图27以及以下所述的具体顺序为限制，应当理解，在其它实施例中，该方法其中部分步骤的顺序可以根据实际需要相互交换，或者其中的部分步骤也可以省略或删除。该方法包括如下步骤：
S2701，当电子设备处于特定状态时，获取第一图像。
S2702，当第一图像包括第一图形码时，获取第二图像，第二图像包括第二图形码，其中，获取第一图像所产生的功耗，小于获取第二图像所产生的功耗，第一图像的图像质量低于第二图像的图像质量，第一图形码的图像质量低于第二图形码的图像质量。
S2703，确定第二图形码所承载的第一码信息以及第二图形码对应的第一应用。
S2704，当接收到确认操作时，通过第一应用显示与第一码信息对应的显示界面。
在本申请实施例中，电子设备可以在处于特定状态时，先在功耗较低的情况下通过第一摄像头获取图像质量较低的第一图像，并在第一图像包括第一图形码的情况下，在功耗较高的情况下通过第二摄像头获取图像质量较高的第二图像，从第二图像中识别第二图形码所承载的第一码信息以及第一应用，再向用户发出第一提示信息，使得用户感知到识别到第二图形码。在接收到用户的确认操作时，可以基于第一应用显示与第一码信息对应的显示界面。由于不需要用户查找第一应用，也不需要从第一应用中查找图形码识别功能，因此极大地提高了识别图形码的效率，同时第一应用的开发人员也不要专门针对识别图形码这一功能进行软件布局和用户引导，降低了识别图形码的成本。且由于是先在功耗较低的情况下通过第一摄像头获取图像质量较低的第一图像，并在初步判断第一图像包括第一图形码的情况下，再次在功耗较高的情况下通过第二摄像头获取图像质量较高的第二图像，也能够减少电子设备识别图形码的功耗。
