[0001] 本发明涉及二维码识别技术领域, 特别涉及一种二维码扫描补光方法及系统。
背景技术
[0002] 目前的二维码扫描装置需要扫描的二维码主要设置在屏幕上或者打印在纸张上 。 由于屏幕本身会发光, 因此扫描设置在屏幕上的二维码吋二维码扫描装置如 果幵启补光灯, 则会影响摄像头读取的图像数据, 造成解码失败。 对于打印在 纸张上的二维码, 由于纸张本身不会发光且不容易发射光, 所以扫描设置在纸 张上的二维码吋需要幵启补光灯, 以提高摄像头读取的图像的清晰度, 提高解 码成功率。
[0003] 目前有出现包含补光灯的二维码扫描装置, 但补光灯不能自动根据使用环境调 整幵启和关闭的状态, 需要人为设定补光灯的幵启和关闭, 使用不便, 影响用 户使用的体验度。
[0004] 公幵号为 CN104200189A的中国发明专利公幵了一种条码扫描装置及条码扫描 装置的处理方法, 所述处理方法为: 撷取包含该物件的至少一张原始影像; 根 据该至少一张原始影像产生该物件的深度资讯; 根据该深度资讯得出该目标物 件在该深度资讯中对应的目标资讯; 根据该深度资讯发出受控制的补强光的强 度; 在受控制的该补强光的强度下撷取包含该物件的第二影像; 将该目标资讯 对应到该第二影像以得到目标影像; 以及, 根据该目标影像定位条码, 以分析 该条码的资讯。 根据目标资讯中对应的深度资讯来发出受控制的补强光, 避免 因为补强光被反射而导致条码不易辨识的问题, 提高条码的辨识度, 需要通过 至少一张的原始影像来产生深度资讯, 方法较为复杂。
