Description

一种图形编码展示方法和装置 技术领域
本说明书涉及互联网技术领域，尤其涉及一种图形编码展示方法和装置。
背景技术
在现代日常生活中，通过扫码终端设备对手机展示的图形编码进行扫描，进而完成支付，取票，互加好友等功能的情景十分普遍。一般情况下，需要将手机贴近扫码终端设备，并将手机展示的图形编码对准扫码终端设备的扫码模块来完成信息读取。如手机通过APP购买电影票后，需要在现场将手机上展示的图形编码对准出票终端设备的扫码模块，以完成扫描并领取电影票。
通常情况下，手机展示的图形编码块相对所在手机屏幕的位置是固定的，这就要求使用者必须先确定好手机图形编码所在区域并准确的放置在扫码终端设备的扫码模块内才能成功进行扫码，此外，一些扫码终端设备会设计一些挡板保护扫码模块，使得一些较大的手机不能很好的放置和扫码，用户体验不好。

在现代日常生活中，通过扫码终端设备(参考图1)对手机展示的图形编码进行扫描，进而完成支付，取票，互加好友等功能的情景十分普遍。一般情况下，需要将手机贴近扫码终端设备，并将手机展示的图形编码对准扫码终端设备的扫码模块来完成信息读取。如手机通过APP购买电影票后，需要在现场将手机上展示的图形编码对准出票终端设备的扫码模块，以完成扫描并领取电影票。
通常情况下，手机展示的图形编码块相对所在手机屏幕的位置是固定的，这就要求使用者必须先确定好手机图形编码所在区域并准确的放置在扫码终端设备的扫码模块 内才能成功进行扫码，此外，一些扫码终端设备会设计一些挡板保护扫码模块，使得一些较大的手机不能很好的放置和扫码，用户体验不好。
针对以上问题，本说明书实施例提供一种图形编码展示方法，以及一种用于执行该方法的图形编码展示装置，下面对本实施例涉及的图形编码展示方法进行详细说明，参见图2所示，该方法可以包括以下步骤：
S201，检测到调用图形编码页面后，启动当前设备的前置图像采集模块进行图像采集；
本说明书中的图形编码，指的是包括二维码、条形码、字符码、网络域名在内的数字对象唯一标识符。在现代日常生活中，以二维码应用最为广泛，举例说明其应用场景：在购买电影票后，购票APP会生成一个特定的二维码用于取票，用户只需要在现场的取票设备的扫码模块处进行二维码展示，即可领取电影票。本说明书下文中，也以二维码代表图形编码进行说明。
当用户打开二维码页面进行展示时，即可视为客户端设备调用了二维码页面，此时可启动当前设备的前置图像采集模块，如启动手机的前置摄像头采集手机前方的图像。
考虑到一些设备可能不具备前置摄像采集模块，可以在检测到调用图形编码页面后增加判断步骤，先判断当前设备是否具备前置图形采集模块，若不具备该模块，则停止本实施例流程，或采用其他方式进行二维码展示。
S202，对采集到的图像进行图像识别，若所述采集到的图像中包含预置的扫码模块的特征，则计算所述扫码模块相对于图形编码当前展示位置的偏移距离；
具体地，进行图像识别之前，可在服务器或客户端设备预先存储多种扫码模块的特征信息，并将所述多种特征信息与采集到的图像进行匹配，确定该采集到的图像中是否包含该多种特征信息中的某一种。
进一步地，可确定结束图像采集的时机，一般地，当用户稳定握持设备时不再移动时，可使用此时采集到的图像进行图像识别，并确定采集到扫码模块相对于图形编码当前展示位置的偏移距离，此时的偏移距离是较稳定不会发生变化的。因此，可检测到当前设备是否处于静止状态，当设备处于静止状态且时间超过预设阈值后，可结束图像采集并对采集到的图像进行图像识别。
同样考虑到一些设备可能不具备感应自身状态的传感器，也可采用另一种方式确定结束图像采集的时机。即：持续采集图像，计算不同图像中的扫码模块相对于图形编码 当前展示位置的偏移距离；如果若干次计算的偏移距离的差距在预设阈值内，则结束图像采集并计算目标展示位置。
进一步地，在一些情况下，用户可能将设备的放置位置与扫码终端的扫码模块偏差较大，既没有将二维码对准扫码模块，也没有将扫码模块至于前置摄像模块的视野内，此时可对用户进行提醒。具体地，在判断用户调用二维码页面并稳定握持设备不动后，若二维码并没有被扫描成功且图像识别后的采集图像中并不包含扫码模块的特征，则启动提醒功能，通过播放语音或设备震动等方式提醒用户重新放置设备。
进一步地，也可在扫码终端的扫码模块的周围增加可感应模块，当用户设备偏移到扫码模块周围后，通过检测扫码终端的可感应模块直接语音提醒用户向上/下/左/右方向移动用户设备。
S203，根据所述偏移距离计算目标展示位置，将所述图形编码在所述目标展示位置进行展示。
在一些情况下，设备可能并不具备前置图像采集模块，因此本说明书还提供了一种在当前设备不具备前置摄像采集模块情况下的图形编码展示方式，具体可参考图3，包括如下步骤：
S301，检测到当前设备不具备前置图像采集模块；
S302，设定至少一个展示位置和展示间隔时间；
S303，将图形编码按照设定的展示间隔时间依次在不同展示位置进行展示。
举例说明，可将设备的中轴线设置为展示路线，沿该中轴线设定多个展示位置，按设定好的间隔时间将二维码依次循环在各个位置进行展示。用户只需要将设备大致放在扫码模块处并稍作等待，屏幕中的二维码可以自行移动并最终对准扫码模块。
本说明书实施例还提供一种更为具体的在图形编码展示方法，参见图4所示，该方法可以包括以下步骤：
S401，检测到调用图形编码页面；
S402，判断当前设备是否具备图像采集模块；
S403，将所述图形编码按照预设的展示策略进行展示，所述预设的展示策略至少包括将图形编码按照预设的不同展示位置进行展示的策略；
S404，启动当前设备的前置图像采集模块进行图像采集；
S405，检测到当前设备处于静止状态且时间超过预设阈值后，结束图像采集并对采集到的图像进行图像识别；
S406，对采集到的图像进行图像识别，若所述采集到的图像中包含预置的扫码模块的特征，则计算所述扫码模块相对于图形编码当前展示位置的偏移距离；
S407，根据所述偏移距离计算目标展示位置，将所述图形编码在所述目标展示位置进行展示。
相应于上述方法实施例，本说明书实施例还提供一种图形编码展示方法装置，参见图5所示，所述装置可以包括：图像采集模块510，偏移计算模块520和计算展示模块530。

计算展示模块530：用于根据所述偏移距离计算目标展示位置，将所述图形编码在所述目标展示位置进行展示。
本说明书实施例还提供一种计算机设备，其至少包括存储器、处理器及存储在存储器上并可在处理器上运行的计算机程序，其中，处理器执行所述程序时实现前述图形编码展示方法，所述方法至少包括：
检测到调用图形编码页面后，启动当前设备的前置图像采集模块进行图像采集；
