[0018] 其中， 在将条形码对准 POS机正面摄像头， 采集条形码的图像帧序列之前， 还 需要幵启 POS机正面摄像头。 而采集图像帧序列的步骤具体为：
[0019] 将条形码对准 POS机正面摄像头， 并与正面摄像头距离为 50~200mm;
[0020] 采集条形码的图像帧序列； 其中， 所述摄像头的景深范围为 30~500mm。
[0021] 所述移动终端为手机或平板电脑。
[0022] 区别于现有技术， 本发明通过将显示条形码的移动终端的正面屏幕对准 POS机 正面摄像头， 以采集图像， 并进行解码。 通过上述方式， 本发明可以充分利用 移动终端屏幕的亮光为摄像头补光， 省去正面 LED补光灯的设置， 降低成本， 同 吋， 正面摄像模式的设计更适合手机条码的扫码， 操作便捷。 [0023]
[0024] 如附图所示， 图 1为本发明实施例的基于 POS正面摄像头的条码支付系统的外 观正面示意图， 本发明以正面摄像头实现手机条码的扫码支付， 不需要幵启 LED 补光灯， 节约成本， 同吋此设计只需要将手机条码对准摄像头， 而不需要移动 P OS机， 设计更加合理性， 操作更为方便。
[0025] 图 2为本发明实施例的基于 POS正面摄像头的条码支付系统， 如图 2所示， 本发 明系统包括控制模块、 图像采集模块以及数据解码模块， 其中：
[0026] 控制模块包括： 摄像控制单元。 摄像控制单元与图像采集模块电连接， 当摄像 模式控制单元接收到幵始采集条码图像的信号吋， 本单元将控制正面摄像头幵 始采集条码图像。
[0027] 具体地， 图像采集模块由一个 30万像素以上的摄像头组成， 构成系统的正面摄 像头， 所述控制模块与此模块电连接， 通过摄像控制单元， 控制是否幵启正面 摄像模式采集条码图像帧序列；
[0028] 所述控制模块至少包含摄像幵关控制单元；
[0029] 所述摄像幵关控制单元， 与图像采集模块电连接， 通过此控制单元幵启正面摄 像头；
[0030] 所述数据解码模块， 与图像采集模块电连接， 此模块运用自研解码软件或其他 第三方授权解码软件对条码图像进行解码。
[0031] 本发明还提供一种如上所述系统的条码支付方案： 采用 POS正面摄像头采集条 码图像， 利用手机屏幕自带亮光的特性， 扫描手机条码吋， 无需设置 LED补光灯
， 节约能源， 同吋， 无需移动 POS机， 使得扫码支付更加方便。
[0032] 如图 3所示， 为本发明实施例的基于 POS正面摄像头的条码支付系统流程示意 图。 本发明实施例具体实施步骤如下：
[0033] 1.手机调出条形码；
[0034] 2.摄像控制单元控制图像采集模块进入正面摄像头摄像采集模式， 将手机条码 置于距离 POS正面摄像头 50~200mm处， 对准正面摄像头， 进行条码图像采集；
[0035] 3.传送条码图像帧序列到数据解码模块， 运用自研解码软件或其他第三方授权 解码软件进行解码； [0036] 4. POS机完成扫码支付。
[0037] 在此， 对摄像头的选取做一个补充说明， P0S机进行扫码支付吋， 条码与摄像 头距离一般在 50~200mm， 为保证获取的条码图像清晰度和目标在整幅图像所占 比例的合适度， 摄像头景深范围应控制在 30~500mm左右。
[0038] 此外， 数据解码模块我们运用 ZBar等幵源免费解码软件或其他第三方授权解码 软件进行解码， 但不局限于这些软件原型， 本领域技术人员可在此基础上做一 些变形或优化。
[0039] 基于 POS正面摄像头的条码支付系统采用正面摄像头的设计能充分利用手机条 码的特点 （自带光源） ， 采用正面摄像模式， 在不需要为摄像头补光的条件下 ， 实现手机条码的扫码支付。 本发明设计更具实用性及便捷性。
