在本申请的描述中，“多个”的含义是两个或者更多，除非另有明确具体的限 定。
图1示出根据本申请一个实施例的一种应用于第一用户设备的识别二维码的方法流程图，该方法包括步骤S11和步骤S12。在步骤S11中，第一用户设备在第一用户与第二用户的视频通话过程中，响应于所述第一用户针对所述第二用户的视频流的轨迹绘制操作，获得所述第一用户绘制的轨迹，根据所述轨迹确定截取区域，并对所述视频流中的所述截取区域执行二维码识别操作；在步骤S12中，若识别成功，第一用户设备对识别得到的二维码信息进行处理。
在步骤S11中，第一用户设备在第一用户与第二用户的视频通话过程中，响应于所述第一用户针对所述第二用户的视频流的轨迹绘制操作，获得所述第一用户绘制的轨迹，根据所述轨迹确定截取区域，并对所述视频流中的所述截取区域执行二维码识别操作。在一些实施例中，在第一用户与第二用户的视频通话过程中，第二用户将其所使用的第二用户设备的摄像头对准需要展示给第一用户的二维码，将该二维码通过视频流的方式发送给第一用户设备，从而在第一用户设备上呈现的第二用户的视频画面上展示该二维码，而完全无需第二用户退出视频通话，也无需第二用户通过拍照或截图的方式将需要展示给第一用户的二维码提供给第一用户，优选地，第二用户需要将第二用户设备当前使用的前置摄像头切换为后置摄像头，将后置摄像头对准需要展示给第一用户的二维码。在一些实施例中，当第一用户看到第二用户的视频画面上展示了二维码时，第一用户可以通过其手指在该视频画面上执行轨迹绘制操作(例如，第一用户的手指在第一用户设备屏幕上的某个位置处按下，在保持手指按下的状态下移动手指)，此时第一用户设备会获得第一用户绘制的轨迹，响应于该轨迹绘制操作对应的轨迹绘制结束事件(例如，第一用户的手指从第一用户设备屏幕上抬起)，根据第一用户当前绘制的轨迹，确定对应的截取区域。在一些实施例中，可以将第一用户绘制的轨迹显示在第一用户设备屏幕上，或者，也可以不在第一用户设备屏幕上显示第一用户绘制的轨迹。在一些实施例中，若第一用户当前绘制的轨迹闭合，将该闭合轨迹所围成的区域确定为截取区域。在一些实施例中，若第一用户当前绘制的轨迹不闭合，则可以通过一条虚拟直线将绘制起始点(例如，手指按下位置处)及绘制终止点(例如，手指抬起位置处)连接起来，得到该绘制轨迹对应的虚拟闭合轨迹，并将该虚拟闭合轨迹所围成的区域确定为截取区域。在一些实施例中，若第一用户当前绘制的轨迹不闭合，还可以在绘制起始 点及绘制终止点分别绘制一条虚拟切线延长线，根据所绘制的两条虚拟切换延长线及第一用户设备的屏幕边界，得到该绘制轨迹对应的虚拟闭合轨迹，并将该虚拟闭合轨迹所围成的区域确定为截取区域。在一些实施例中，对第二用户的视频画面中的该截取区域对应的视频帧图像区域执行二维码识别操作，识别得到该视频帧图像区域上所展示的二维码中包含的二维码信息。在一些实施例中，对第二用户的视频画面中的该截取区域对应的视频帧图像区域执行二维码识别操作，而不是对第二用户的视频画面中的全部显示区域执行二维码识别操作，可以加快二维码的识别速度，提高二维码的识别精度和识别效率。
在步骤S12中，若识别成功，第一用户设备对识别得到的二维码信息进行处理。在一些实施例中，若识别成功，可以直接对识别得到的二维码信息进行处理，或者，还可以根据第一用户的用户授权信息或用户标识信息(例如，token、uuid(Universally Unique Identifier，通用唯一识别码)等)，对识别得到的二维码信息进行处理，或者，还可以根据该视频通话应用已绑定的第一用户的个人真实身份信息，对识别得到的二维码信息进行处理。
本申请能够在第一用户与第二用户的视频通话过程中，响应于所述第一用户针对所述第二用户的视频流的轨迹绘制操作，获得所述第一用户绘制的轨迹，根据所述轨迹确定截取区域，并对所述视频流中的所述截取区域执行二维码识别操作，从而使得第二用户仅需将其摄像头对准需要展示给第一用户的二维码，而完全无需退出视频，也无需通过拍照或截图将二维码提供给第一用户，而第一用户仅需在屏幕上针对第二用户所展示的二维码执行轨迹绘制操作，便能使得第一用户设备快速且方便地识别出该二维码，这使得视频通话过程中针对二维码的识别极为简便且准确，能够为参与视频通话的用户提供极大的便利，并且仅对视频流中的该截取区域对应的视频帧图像区域执行二维码识别操作，而不是对视频流的全部显示区域执行二维码识别操作，可以加快二维码的识别速度，提高二维码的识别精度和识别效率。
