特定条形码及其形成方法
本申请要求申请号(CN201410193210.7)的中国专利申请的本国优先权。该中国专利申请CN201410193210.7的全部内容被以引用方式包含于此。
技术领域
本发明涉及条形码，更具体地，涉及特定条形码及其形成方法。
背景技术
目前各个领域都普遍采用一维条形码和二维条形码作为物品的流通、仓储等过程中的识别标识，大量传统领域还是以一维条形码为主，比如香烟，食品以及各种日用品的消费领域。
条形码技术是在计算机应用发展过程中，为消除数据录入的“瓶颈”问题而产生的，可以说是最“古老”的自动识别技术。1973年，美国统一代码委员会选定IBM公司的条形码系统，作为北美的通用产品代码，即UPC码，应用于食品零售业，利用条形码技术进行自动销售，大大加快了食品的流通。现在已经是广泛应用于商业、邮政、图书管理、仓储、交通、工业生产过程控制等领域的一种自动识别技术，具有输入速度快、准确度高、成本低、可靠性强等优点，在当今的自动识别技术中占有重要的地位。
如图1所示，条形码是由一组规则排列的条、空以及对应的字符组成的标记，“条”指对光线反射率较低的部分，“空”指对光线反射率较高的部分，这些条和空组成的数据表达一定的信息，并能够用特定的设备识读，转换成与计算机兼容的二进制和十进制信息。通常对于每一种物品，它的编码是唯一的，对于普通的一维条形码来说，还要通过数据库建立条形码与商品信息的对应关系，当条形码的数据传到计算机上时，由计算机上的应用程序对数据进行操作和处理。因此，普通的一维条形码在使用过程中仅作为识别信息，它的意义是通 过在计算机系统的数据库中提取相应的信息而实现的。常用的一维码的码制包括：EAN码、39码、交叉25码、UPC码、128码、93码，ISBN码，及Codabar(库德巴码)等。
不同的码制有它们各自的应用领域：
EAN码：是国际通用的符号体系，是一种长度固定、无含意的条形码，所表达的信息全部为数字，主要应用于商品标识；
39码和128码：为目前国内企业内部自定义码制，可以根据需要确定条形码的长度和信息，它编码的信息可以是数字，也可以包含字母，主要应用于工业生产线领域、图书管理等；
93码：是一种类似于39码的条形码，它的密度较高，能够替代39码；
25码：主要应用于包装、运输以及国际航空系统的机票顺序编号等；
Codabar码：应用于血库、图书馆、包裹等的跟踪管理；
ISBN：用于图书管理。
一维条形码的编码是唯一的。例如EAN-13，由前缀码、厂商识别码、商品项目代码和校验码组成。前缀码是国际EAN组织标识各会员组织的代码，我国为690-695；厂商代码是EAN编码组织在EAN分配的前缀码的基础上分配给厂商的代码；商品项目代码由厂商自行编码；校验码为了校验代码的正确性。在编制商品项目代码时，厂商必须遵守商品编码的基本原则：对同一商品项目的商品必须编制相同的商品项目代码；对不同的商品项目必须编制不同的商品项目代码。一维条形码只是在一个方向(一般是水平方向)表达信息，而在垂直方向则不表达任何信息，其一定的高度通常是为了便于阅读器的对准。一维条形码的应用可以提高信息录入的速度，减少差错率，但是一维条形码也存在一些不足之处：数据容量较小：30个字符左右；只能包含字母和数字；条形码尺寸相对较大(空间利用率较低)；条形码遭到损坏后便不能阅读。现在商品的溯源等应用都要求是一件一码，就是每个商品都具有唯一的标识。但是由于一维条形码编码容量的关系， 一维条形码的每个编码表示的是一种商品，即一品一码，不能标识单个商品的唯一性。所以在继承原有一维条形码的所有性质不变的前提下，并且提高目前一维条形码的容量的方法来实现一件一码标识，能够给商家实现一件一码所具有的溯源等所有应用带来附加价值。
发明内容
根据上述对背景技术以及存在的技术问题的理解，在继承原有一维条形码所有性质不变的前提下，并且提高目前一维条形码的容量的方法将是非常有益的。

根据本发明的一个实施例，在对所述特定条形码进行识别时，通过所述设备，识别所述一维条形码信息与所述彩色信息和/或灰度信息，识别后的所述一维条形码信息结合识别后的所述彩色信息和/或灰度信息使得所述特定条形码具有一物一码的特征。

图1示出了一维条形码的示意图；
图2示出了彩色二维条形码的示意图；
图3示出了色度饱和度以及明度示意图；以及
图4示出了彩色二维条形码的又一个示意图。
在图中，贯穿不同的示图，相同或类似的附图标记表示相同或相似的装置(模块)或步骤。
具体实施方式
在以下优选的实施例的具体描述中，将参考构成本发明一部分的所附的附图。所附的附图通过示例的方式示出了能够实现本发明的特定的实施例。示例的实施例并不旨在穷尽根据本发明的所有实施例。可以理解，在不偏离本发明的范围的前提下，可以利用其他实施例，也可以进行结构性或者逻辑性的修改。因此，以下的具体描述并非限制性的，且本发明的范围由所附的权利要求所限定。
图1示出了传统的一维条形码的示意图，关于该图的描述已经 在背景技术中给出，在此不再赘述。
商品一维条形码的标准尺寸是37.29mm×26.26mm，放大倍率是0.9～2.0。当印刷面积允许时，可以选择1.0倍率以上的一维条形码，以满足识读要求。例如，可以在本来的惯用白色底色上，先印刷3*10色块矩阵，即采用3种不同的颜色填充于3*10的色块矩阵上。该色块矩阵不超过标准尺寸要求，为了减少识读设备的要求，可以让色块矩阵中的色块尽量大一些，例如优先考虑3mm*3mm的大小。当然，根据实际条形码大小和需求，色块矩阵中的色块并不一定要使用方块，矩形、正方形、圆形或任何其他形状都可以，其大小也可以根据需要而改变。
由于条形码的识读是通过条和空的颜色对比为实现的，一般情况下，只要能够满足对比度(pcs值)的要求的颜色即可使用。通常采用浅色作空的颜色，例如白色、橙色、黄色等，采用深色作为条的颜色，例如黑色、暗绿色、深棕色等。最常见的搭配是黑条白空。根据条形码检测的实践经验，红色、金色、浅黄色不宜作为条的颜色，透明、金色不能作为空的颜色。在本发明的实施例中条的颜色采用黑色，背景色和白色组成空的颜色。本领域普通技术人员应该理解的是，条和空的颜色并不限于黑色和白色，在考虑识读设备的情况下，条和空的颜色根据需要可以选用其它任何各种颜色，色块矩阵中各个色块的颜色根据需要也可以选用其它任何各种颜色。
当选用3*10的色块矩阵时，在一实施例中，采用3种不同颜色填充于色块矩阵上，其能够表示的商品最大标识数量为3的30次方，总数为205891132094649，即超过200万亿的个数的商品标识，这个数量应该能够满足例如商家一件一码或其它应用的要求。本领域普通技术人员应该理解的是，在采用3种不同颜色填充时，色块矩阵的大小也可以是4*8，3*9或3*11等，其对应的商品最大标识数量分别为：3的32次方，3的27次方或3的33次方等；采用N(N大于等于2的自然数)填充于M个色彩矩阵时，对应的商品标识个数为N的M次方商品标识，在降低了制作工艺的复杂度和难度 的基础上，可控的大大增加了现有一维码的容量，实现商品的一品一码。
此外，色块矩阵中的各个色块之间可以是不连接。本领域的普通技术人员应该理解的是，色块矩阵中的各个色块的连接方式并不限于图2中所示的连接方式，任何一种符合识读设备要求的方式都可以，例如横向连接或不连接，纵向连接或不连接。
在本发明的一个实例中，如图2所示出的基于彩色背景的新型二维码，首先在一种适合于形成一维条形码的材料上，根据一维条形码的编码规则，形成一个一维条形码。其次在所形成的一维条形码上叠加彩色信息和/或灰度信息。本领域技术人员普通技术人员应该理解的是，在本实施例中所述的一维条形码可以是任何形式的一维条形码码制。一维条形码包含第一数据信息，第一数据信息可以是，例如商品的序列号或商品项目代码。在一维条形码上叠加的彩色信息和/或灰度信息包含第二数据信息，第二数据信息可以是，例如具有一维条形码所包含的商品序列号的某件商品的标识信息。通常情况下，商品序列号或商品项目代码表示某一商品，即一品一码。而商品的标识信息标识某一商品的某一件，即一件一码。此外，在一维条形码上叠加了彩色信息和/或灰度信息后，识读设备可以分别对第一数据信息和第二数据信进行识别，也可以通过识读设备同时对第一数据和第二数据进行识别。识读设备在识别第一数据信息时仍然保持误判率低于40％。本领域普通技术人员可以理解的是，本发明的实施例中的识读设备并不仅限于具有捕捉图像的功能的便携式电子装置，也可以是能够分别识别和/或存储第一数据信息和第二数据信息的并满足对第一数据信息和/或第二数据信息误判率要求的任何设备，包括扫描器等。条码扫描器通常也被人们称为条码扫描枪/阅读器，是用于读取条码所包含信息的设备，可分为一维、二维条码扫描器。
扫描器的基本工作原理为：由光源发出的光线经过光学系统照射到条码符号上面。被反射回来的光经过光学系统成像在光电转换 器上，经译码器解释为计算机可以直接接受的数字信号。条码扫描器广泛应用于商业POS收银系统、快递仓储物流、图书服装医药、银行保险通讯等多个领域的需求。条码扫描器的主要技术参数包括例如分辨率、扫描景深、扫描宽度、扫描速度、一次识别率和误码率。识别成功时，扫描器会识别出一段长度的数码，识别失败时，该数码不产生。其中，一次识别率表示的是首次扫描读入的标签数与扫描标签总数的比值。举例来说，如果每读入一只条形码标签的信息需要扫描两次，则一次识别率为50％。误码率是反映一个机器可识别标签系统错误识别情况的极其重要的测试指标。误码率等于错误识别次数与识别总次数的比值。对于一个条形码系统来说，误码率是比一次识别率低更为严重的问题。将被扫描的特定二维码置于扫描工作范围内，进行重复机械式的扫描得出识别率，100％减去识别率即为误判率。识别成功时，扫描枪会识别出一段长度的数码，识别失败时，该数码不产生。例如，美国霍尼韦尔Honeywell MS1690二维条码扫描枪的分辨率为130万像素，扫描景深为0mm-230mm。
在一个实施例中，所叠加的包含彩色信息和/或灰度信息的色块矩阵可以完全叠加于对应的一维条形码区域上，也可以是部分地叠加于对应的一维条形码区域上。
在一个实施例中，如图4所示出，色块矩阵中的色块是矩形的且长度和一维条形码的在纵向上条的长度可以是相同的，也即色块矩阵含有1*N个色块，色块矩阵中的色块之间横向可以是不连接的。各个色块的宽度可以是一样的也可以是不一样的，色块矩阵叠加或部分叠加与一维条形码上。
HSL色彩模式是工业界的一种颜色标准，是通过对色度(H：Hue)、饱和度(S：Saturation)、明度(L：Lightness)三个颜色通道的变化以及它们相互之间的叠加来得到各式各样的颜色的，HSL即是代表色度，饱和度，明度三个通道的颜色，这个标准几乎包括了人类视力所能感知的所有颜色，是目前运用最广的颜色系统之一。
如图3所示出的HSL中的色度分量，代表的是人眼所能感知的颜色范围，这些颜色分布在一个平面的色相环上，取值范围是0°到360°的圆心角，每个角度可以代表一种颜色。色度值的意义在于，我们可以在不改变光感的情况下，通过旋转色相环来改变颜色。在实际应用中，我们需要记住色相环上的六大主色，用作基本参照：360°/0°红、60°黄、120°绿、180°青、240°蓝、300°洋红，它们在色相环上按照60°圆心角的间隔排列。
HSL中的饱和度分量，指的是色彩的饱和度，它用0％至100％的值描述了相同色相、明度下色彩纯度的变化。数值越大，颜色中的灰色越少，颜色越鲜艳，呈现一种从理性(灰度)到感性(纯色)的变化。
HSL中的明度分量，指的是色彩的明度，作用是控制色彩的明暗变化。它同样使用了0至1的取值范围。数值越小，色彩越暗，越接近于黑色；数值越大，色彩越亮，越接近于白色。
RGB色彩模式是工业界的一种颜色标准，是通过对红(R：Red)、绿(G：Green)、蓝(B：Blue)三个颜色通道的变化以及它们相互之间的叠加来得到各式各样的颜色的，RGB即是代表红、绿、蓝三个通道的颜色。RGB色彩模式使用RGB模型为图像中每一个像素的RGB分量分配一个0-255范围内的强度值。RGB图像只使用三种颜色，就可以使它们按照不同的比例混合，在屏幕上呈现16777216(256*256*256)种颜色。
HSL中的各个分量可以分别由公式(1)来表示：
Figure PCTCN2015078180-appb-000001
Figure PCTCN2015078180-appb-000002
其中，max和min分别指RGB中最大数值和最小数值。举个例子，当R＝186、G＝201、B＝19时，max＝201、min＝19。
在如图2所示出的实施例中，当彩色信息叠加在一维条形码的空并同时叠加于相邻的条上时(叠加于条上的色彩于视觉上未显示)，彩色信息为纯红至淡绿变化区间内的至少一种颜色。可选的，当HSL中的色度为大于等于0°并且小于等于60°时，饱和度大于等于90％并且明度大于等于0.5。表1列出了根据图2所示的实施例的三种填充于空上的颜色信息以及其所对应的识别率。本实施例中采用3种颜色叠加于3*3的矩阵色块为例，可实现3的9次方个不同的一件一码的信息容量，当然也可采用N*M个矩阵排布实现更多的信息容量。
表1填充于空上的彩色信息和识别率
Figure PCTCN2015078180-appb-000003
可选的，当HSL中的色度大于60°并且小于等于90°时，饱和度大于等于90％并且明度大于等于0.75。本领域技术人员可以确定，在此，“淡绿”可表示为色度为90°，饱和度为90％，明度为0.75。表2列出了根据图2所示的实施例的填充于空上的颜色信息以及其所对应的识别率。
表2填充于空上的彩色信息和识别率
识别率 HSL1 RGB1
64％ 60°，100％，0.8192 223，255，163
78％ 73.57°，90.98％，0.7896 229，251，170
93％ 72.31°，100％，0.8662 241，255，188
如上述实验数据，由于多种颜色组合的矩阵模块的整体识别率取决于单个彩色信息的最低的识别率，在另一实施例中可采用N(N大于等于2的自然数)种对应于上述区间的彩色信息填充于空上，达到对应于彩色信息识别率高于60％，及误判率低于40％的目的，并大幅增加原始一维码的容量。
当彩色信息叠加在一维条形码的条上时，彩色信息为纯绿至棕红变化区间内的至少一种颜色。可选的，当HSL中的色度大于等于120°并且小于等于300°时，明度小于等于0.5。可选的，当HSL中的色度大于300°并且小于等于330°时，饱和度小于等于50％，明度小于等于0.25。表3列出了三种填充于条上的颜色信息即填充于A、B、C、D以及其所对应的识别率。如图4所示，本实施例中选取了18个条的空间进行色彩添加，当对应于条的色彩区间选取3个彩色信息进行填充排布时，可实现3的18次方个不同一件一码的信息容量，在填充条的基础上另一实施例中与条相邻空的位置上同时叠加图2的色彩信息，可对应增加一件一码的信息容量。
表3填充于条上的彩色信息和识别率
Figure PCTCN2015078180-appb-000004
在图4的特定的实施例中，例如，颜色A(例如纯绿)可以表示为色度为120°，饱和度为100％，明度为0.5；颜色B(例如纯蓝)可以表示为色度为240°，饱和度为100％，明度为0.5；颜色C(例如墨绿)可以表示为色度为120°，饱和度为50％，明度为0.375；颜色D(例如棕红)可以表示为色度为315°，饱和度为50％，明度为0.25；其中颜色A、B、C和D均可采用HSL中对应的规定彩色信息，由于多种颜色组合的矩阵模块的整体识别率取决于单个彩色信息的最低的识别率，在另一实施例中可采用N(N大于等于2的自然数)种对应于上述区间的彩色信息填充于条上，达到对应于彩色信息识别率高于60％，及误判率低于40％的目的，并大幅度增加原始一维码的容量；在另一实施例中对应于每一竖直的条可于部分区域填充同一种彩色信息，或者于相邻的若干条的部分区域填充同一种彩色信息，实现对应的识别率和信息容量。
灰度也就是所谓的色阶或灰阶，是指亮度的明暗程度。在本申请中，采用例如灰度等级100，0表示纯白，100表示纯黑。在灰度等级为100的标准下，当将灰度信息叠加在一维条形码的条上时，灰度等级为大于等于40；在一实施例中图4中的色彩区间内灰度等 级为35时，识别率低于60％，于灰度等级为45、55进行实验，识别率高于60％。当将灰度信息叠加在一维条形码的空上时，灰度等级为小于等于10；在一实施例中于图2中的色彩区间内于灰度等级为5时，识别率高于60％，于灰度等级为25、15进行实验，识别率低于60％。
由于条形码的扫描识别是基于条形码中条与空的颜色对比来实现的，因此，本领域技术人员通常认为，不可以在一维条形码上叠加彩色信息或灰度信息，否则往往会导致该条形码不能正常被识别，例如该条形码的识别率过低。根据本申请的上述实施例，本领域技术人员应能理解，本申请恰恰克服了该技术偏见，通过在一维条形码上叠加彩色信息或灰度信息不仅增加了条形码的信息容量，还使得新获得的条形码与原有的一维条形码技术相兼容，即利用原有的条形码扫描设备便可正常读取对应的一维条形码信息。
对于本领域技术人员而言，显然本发明不限于上述示范性实施例的细节，而且在不背离本发明的精神或基本特征的情况下，能够以其他的具体形式实现本发明。因此，无论如何来看，均应将实施例看作是示范性的，而且是非限制性的。此外，明显的，“包括”一词不排除其他元素和步骤，并且措辞“一个”不排除复数。装置权利要求中陈述的多个元件也可以由一个元件来实现。第一，第二等词语用来表示名称，而并不表示任何特定的顺序。
