具体实施方式
下面将结合本发明实施例中的附图,对本发明实施例中的技术方案进行清楚、完整地描述,显然,所描述的实施例仅仅是本发明一部分实施例,而不是全部的实施例。基于本发明中的实施例,本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例,都属于本发明保护的范围。
为了简化图形二维码识读过程的用户操作,提高用户体验,本申请实施例提供了一种图形二维码的识读方法及装置。
首先需要说明的是,本申请实施例所提供的一种图形二维码的识读方法及装置可以应用于具有触摸屏幕的电子设备,其中,该电子设备可以为具有触摸屏幕的智能手机、平板电脑、电脑等电子设备。
下面首先对本申请实施例所提供的一种图形二维码的识读方法进行介绍。
如图1所示,一种图形二维码的识读方法,应用于具有触摸屏幕的电子设备,所述方法包括以下步骤:
S101,在所述触摸屏幕上显示识读界面;
一般情况下,当电子设备获得用户发出的关于打开识读界面的指令后,便可以在触摸屏幕上显示识读界面,进而,后续用户则可以在该识读界面上发出操作手势,例如,拖动手势、释放手势、点击手势等,而电子设备则可以通过该识读界面检测用户的操作手势。
可以理解的是,用户可以通过按动电子设备上的某个预设按钮,或者点击电子设备触摸屏幕上的预设应用程序或预设按钮等方式,来发出上述关于打开识读界面的指令。当然,对于一些具有接收语音命令功能电子设备,用户还可以通过语音来发出该关于打开识读界面的指令,在此不做具体限定。
具体的,该识读界面可以包括与界面内容相关的图形二维码及扫描区域。其中,界面内容可以为文字、图片等任意内容;图形二维码可以为QR码、鼎九码等任意二维码;扫描区域则用于扫描该图形二维码。图2为本申请实施例所提供的一种识读界面的示意图,为符合用户的拖动操作习惯,方便后续用户对图形二维码210的拖动操作,图形二维码210可以显示于识读界面上方,扫描区域220可以显示于识读界面下方。
S102,通过所述触摸屏幕检测用户对所述图形二维码的拖动手势,并响应所检测到的拖动手势,移动所述图形二维码;
用户可以通过触摸屏幕对上述图形二维码进行操作,例如,用户可以按住该图形二维码,并拖动该图形二维码。当用户通过触摸屏幕对图形二维码进行拖动时,电子设备便可以通过该触摸屏幕检测到用户的拖动手势。进而,响应所检测到的拖动手势,移动该图形二维码。
作为本申请实施例的一种实施方式,电子设备响应所检测到的拖动手势,移动该图形二维码的方式可以包括以下步骤:
记录所述拖动手势的拖动点;
按照所述拖动点形成的轨迹,移动所述图形二维码。
其中,上述拖动点即为用户对电子设备触摸屏幕的触控点,一般为用户手指与触摸屏幕的接触点。用户在拖动上述图形二维码的过程中,电子设备 记录用户对触摸屏幕的触控点,该触控点会形成一条轨迹,电子设备可以按照该轨迹移动该图形二维码,也就是说,电子设备可以使该图形二维码跟随用户手指的移动而改变位置。这样可以方便用户观察该图形二维码当前所在位置,以便用户确定何时停止拖动该图形二维码,同时视觉效果也比较美观。
S103,当检测到用户对所述图形二维码的释放手势后,判断所述图形二维码是否进入所述扫描区域,如果是,则执行步骤S104;
在用户移动上述图形二维码的过程中,电子设备可以通过触摸屏幕实时检测用户的操作手势,当电子设备检测到用户对该图形二维码的释放手势时,表明用户已经完成对该图形二维码的拖动操作,那么电子设备则可以判断该图形二维码是否进入扫描区域,以便后续对该图形二维码进行扫描。
其中,上述释放手势一般即为用户停止拖动操作,从触摸屏幕上抬起手指,也就是说,用户不与触摸屏幕接触,不再按住上述图形二维码。这与通常的理解是一致的。
作为本申请实施例的一种实施方式,判断图形二维码是否进入扫描区域的方式可以为:
计算所述图形二维码中第一预设点与所述扫描区域中第二预设点的距离,并判断所述距离是否不大于第一预设阈值,如果是,确定所述图形二维码进入所述扫描区域;如果否,确定所述图形二维码未进入所述扫描区域。
其中,上述第一预设点可以为图形二维码中的任意一点,在此不做具体限定。一般情况下,如果该图形二维码为矩形,则可以将矩形的两条对角线的交点作为该第一预设点;如果该图形二维码为圆形,则可以将圆形的圆心作为该第一预设点。
同样的,上述第二预设点也可以为扫描区域中的任意一点,在此不做具体限定。例如,如果该扫描区域为矩形,则可以将矩形的两条对角线的交点作为该第二预设点;如果该扫描区域为圆形,则可以将圆形的圆心作为该第二预设点。
上述第一预设阈值可以由本领域技术人员根据图形二维码和扫描区域的大小等因素确定,在此不做具体限定,例如,可以为0.5厘米、1厘米、1.5厘 米等。
可以理解的是,当图形二维码中第一预设点与扫描区域中第二预设点的距离不大于第一预设阈值时,说明该图形二维码大部分已经进入该扫描区域中,此时用户很可能需要识读该图形二维码,查看识读结果,那么便可以认为该图形二维码进入该扫描区域。
而当图形二维码中第一预设点与扫描区域中第二预设点的距离大于第一预设阈值时,说明该图形二维码只有小部分进入了该扫描区域,或者完全没有进入该扫描区域,那么说明用户对该图形二维码的拖动操作可能是一个误操作,用户并不需要识读该图形二维码,所以,此时便可以确定该图形二维码未进入该扫描区域,当然后续也就不需要对该图形二维码进行识读操作。
作为本申请实施例的另一种实施方式,判断图形二维码是否进入描区域的方式还可以为:
计算所述图形二维码与所述扫描区域的重合部分的面积,并判断所述面积是否大于第二预设阈值,如果是,确定所述图形二维码进入所述扫描区域;如果否,确定所述图形二维码未进入所述扫描区域。
需要说明的是,上述第二预设阈值可以由本领域技术人员根据图形二维码和扫描区域的大小等因素确定,在此不做具体限定,例如,可以为3平方厘米、4平方厘米、5平方厘米等。
由于图形二维码与扫描区域的重合部分的面积大小可以说明二者的重合程度,所以还可以通过该面积的大小来确定图形二维码是否进入了扫描区域。具体的,当图形二维码与扫描区域重合部分的面积大于第二预设阈值时,说明该图形二维码大部分已经进入该扫描区域中,此时用户很可能需要识读该图形二维码,查看识读结果,那么便可以认为该图形二维码进入该扫描区域。
而当图形二维码与扫描区域重合部分的面积小于第二预设阈值时,说明该图形二维码只有小部分进入了该扫描区域,或者完全没有进入该扫描区域,那么此时用户对该图形二维码的拖动操作可能是一个误操作,用户并不需要识读该图形二维码,所以,此时便可以确定该图形二维码未进入该扫描区域,当然后续也就不需要对该图形二维码进行识读操作。
S104,识读所述图形二维码并在所述触摸屏幕上显示所识读出的内容。
在确定图形二维码进入扫描区域后,电子设备便可以对该图形二维码进行识读,然后将识读出的内容显示在触摸屏幕上,以供用户观看,或进行进一步操作。
一般情况下,上述所识读出的内容与界面内容是相关的,如图2和图3所示,所识读出的内容一般是与界面内容即“张碧晨《时光笔墨》MV”等相关的内容,例如,可能是关于《时光笔墨》MV的图片、《时光笔墨》MV视频等内容。进而,用户则可以通过点击、滑动等操作观看该识读出的内容。当然,电子设备也可以直接将该识读出的内容展示给用户观看,例如,可以直接播放《时光笔墨》MV视频等。
作为本申请实施例的一种实施方式,识读图形二维码并在触摸屏幕上显示所识读出的内容的方式可以包括以下步骤:
在所述扫描区域的预设位置显示所述图形二维码,以使所述图形二维码完全显示在所述扫描区域中;
扫描所述图形二维码,并根据预先设置的解码数据库对扫描到的图形二维码进行解码,得到解码结果,并在所述触摸屏幕上显示所述解码结果对应的内容。
为了避免出现无法识读图形二维码的问题,同时确保识读结果的准确,当判断出图形二维码已经进入扫描区域后,一般可以将该图形二维码显示在扫描区域的预设位置,以使该图形二维码完全显示在该扫描区域中。可以理解的是,该预设位置一般可以为扫描区域的中心位置(如图3所示),当然也可以是扫描区域的其他位置,只要能够使该图形二维码完全显示在该扫描区域中,可以对该图形二维码进行扫描,不影响扫描结果即可,在此不做具体限定。
在扫描区域的预设位置显示图形二维码后,便可以对该图形二维码进行扫描,具体的,电子设备可以根据预先设置的解码数据库对扫描到的图形二维码进行解码,得到解码结果,并在触摸屏幕上显示解码结果对应的内容即所识读出的内容。另外,需要强调的是,本申请实施例中,扫描区域的生成 方式可以采用现有技术中任一种扫描框的生成方式,并且,扫描位于扫描区域内的图形二维码的过程也可以为现有技术。
需要说明的是,上述预先设置的解码数据库可以为与图形二维码类型对应的解码数据库。举例而言,如果该图形二维码为鼎九码,那么该预先设置的解码数据库便为能够对鼎九码进行解码的数据库;如果该图形二维码为QR码,那么该预先设置的解码数据库便为能够对QR码进行解码的数据库。进一步的,为了使电子设备可以对任意类型的图形二维码进行识读,该预先设置的解码数据库也可以包括各种类型的图形二维码对应的解码数据,在此不做具体限定。
进一步需要说明的是,该预先设置的解码数据库可以设置在电子设备中,为了减少对电子设备内存的占用,提高电子设备运行速度,也可以将该预先设置的解码数据库设置在与电子设备建立通信连接的服务器中。可以理解的是,电子设备与该服务器可以为有线连接或无线连接等连接方式,其中,无线连接可以为WIFI连接或蓝牙连接等,在此不做具体限定。
在识读过程中,如果预先设置的解码数据库设置在电子设备本地,电子设备则可以调用该预先设置的解码数据库对该图形二维码进行解码,得到相应的解码结果,并在触摸屏幕上显示解码结果对应的内容即所识读出的内容。
如果预先设置的解码数据库设置在与电子设备建立通信连接的服务器中,电子设备则可以将扫描到的图形二维码发送至该预先设置的解码数据库,该预先设置的解码数据库对接收到的该图形二维码解码进行解码,进而得到解码结果,并将该解码结果发送至电子设备,电子设备接收到该解码结果后,便可以在触摸屏幕上显示解码结果对应的内容即所识读出的内容。
上述预先设置的解码数据库对图形二维码解码进行解码的方式,可以采用现有任意一种解码方式,只要可以对图形二维码解码进行解码,获得准确的解码结果即可,在此不做具体说明及限定。
可见,本实施例所提供的方案中,电子设备首先在触摸屏幕上显示识读界面,通过该触摸屏幕检测用户对图形二维码的拖动手势,并响应所检测到的拖动手势,移动图形二维码,当检测到对图形二维码的释放手势后,判断 图形二维码是否进入扫描区域,如果是,则识读图形二维码并在触摸屏幕上显示所识读出的内容。由于在图形二维码识读过程中,电子设备可以识读本身触摸屏幕上显示的图形二维码,用户不需要使用另一台设备对该图形二维码进行扫描,操作非常简单方便,用户体验舒适。
作为本申请实施例的一种实施方式,上述方法还可以包括:
当所述图形二维码未进入所述扫描区域时,将所述图形二维码显示于初始位置。其中,初始位置为图形二维码被移动之前所显示的位置。
如果在步骤S103中,确定上述图形二维码未进入扫描区域,说明此时用户不需要识读该图形二维码,那么为了方便用户下一次的拖动操作,可以将该图形二维码显示于初始位置,也就是步骤S101中该图形二维码所显示的位置,而不是将该二维码显示在检测到用户释放手势时的拖动点位置,这样可以避免界面发生混乱,影响界面美观及用户观看界面。
举例而言,如图3所示,如果在步骤S103中确定上述图形二维码未进入扫描区域,就可以将该图形二维码显示在初始位置230。
需要说明的是,图2和图3中虽然出现了图形二维码和扫描区域的形状、类型、位置,但是图2和图3中所示的图形二维码和扫描区域的形状、类型、位置只是本申请实施例的一种可行方案,并不能构成对本申请实施例所提供的图形二维码和扫描区域的限定。
相应于上述方法实施例,本申请实施例还提供了一种图形二维码的识读装置,下面对本申请实施例所提供的一种图形二维码的识读装置进行介绍。
