Description
本发明涉及宝石鉴定领域，具体的说是一种用于识别宝石身份的方法及其识别系统。
宝石是指经过琢磨和抛光后，可以达到珠宝工艺要求的石料或矿物材料。宝石色泽美丽、硬度高、在大气和化学药品作用下不起变化，一经琢磨和抛光后，其外观就不会改变。宝石是矿物中最美丽而贵重的一类石，它们颜色鲜艳，质地晶莹，光泽灿烂，坚硬耐久，同时赋存稀少，是可以制作首饰等用途的天然矿物晶体，如钻石、水晶、祖母绿、红宝石、蓝宝石和金绿宝石(变石、猫眼)、碧玺等；也有少数是天然单矿物集合体，如冰彩玉髓、欧泊。
由于宝石的稀缺以及价格的昂贵，宝石产生后绝大部分都是具备鉴定证书的，它由经过国际专业机构或者国家认证机构认证的专业检测机构出具，既是业内交易的质量凭证，更是让消费者放心消费的重要依据。
检测机构根据珠宝首饰的不同品种，出具不同格式的鉴定证书，比如钻石分级证书、镶嵌钻石分级证书、珠宝玉石鉴定证书、贵金属饰品纯度检验证书等，但是主要的内容大体都是相同的，一般均会标注检测编号、宝石/饰品名称、包括镶嵌物和载体在内的总重量、饰品的照片、鉴定师姓名、鉴定日期及对不同品种饰品特性的一些定性或定量的描述，并在证书上标明鉴定机构名称、获准认证的标志以及珠宝玉石判别鉴定依据的标准。这样的证书可以作为该饰品的身份证明，具有法律效力。
但是上述纸类证书容易遗失、甚至被仿造或“克隆”，并且当宝石在进行二次销售时，对于宝石身份的识别仅靠此证书，相对来说很难具有信服力。
中国专利CN 106525746A宝石测试仪及宝石鉴别方法，公开了一种利用天然钻石和合成钻石对红外线反射程度的不同来区分天然钻石和合成钻石的设备及其鉴别方法，但是此装置及方法仅是用于鉴别真假钻石，却不能对钻石身份的唯一性做出准确判断。
中国专利CN 1264445 C《宝石用激光划痕系统及划痕鉴别方法》公开了一种钻石及刻面宝石的标注及其鉴别方法，主要依靠在钻石或宝石表面某处(通常是腰部)用冷激光刻字符串、Logo或其它标识，使得钻石及刻面宝石形成独特的“指纹”，也是目前普遍采用的一种方法。现有技术中常用的标记方式之一如附图1所示，但是，这样的“指纹”易于被篡改或复制(克隆)，从而无法确定宝石身份的唯一性。

下面结合具体实施例对本发明做进一步说明。
本发明涉及一种用于识别宝石身份的方法，如图2所示，包括如下几个步骤：
一种用于识别宝石身份的方法，包括如下几个步骤：
(1)宝石加工完成后，对宝石进行测量，得到该宝石的重量参数及宝石的几何结构特征参数，并将测得的上述参数信息以及宝石的类别保存至宝石身份识别数据库中，即图2中S1步骤所示；
(2)测量待识别身份的宝石的重量参数及几何结构特征参数，即图2中S2步骤所示；
(3)将得到的待识别身份的宝石的上述参数，与宝石身份识别数据库中的
宝石的重量参数及宝石的几何结构特征参数进行比对，若待识别身份的宝石的测量参数与宝石身份识别数据库中预存的参数值一致，则可以唯一确认该待识别身份的宝石的身份；若待识别身份的宝石的测量参数之一与宝石身份识别数据库中预存的参数值不一致，则可以停止对该待识别身份的宝石的身份确认；即图2中S3步骤所示。
作为一种优选的实施方式，几何结构特征参数包括刻面宝石的几何结构特征参数和素面宝石的结构特征参数；其中，刻面宝石的几何结构特征参数包括宝石各个刻面的周长、各个刻面的面积、各个刻面与腰面的角度、宝石的腰部波形、宝石的琢型、宝石的长宽高以及宝石的3D模型；素面宝石的结构特征参数包括宝石表面的弧度、宝石的表面积、宝石的琢型、宝石的长宽高以及宝石的3D模型。
本方法中涉及的处理系统还可以根据测得的几何结构特征计算得到宝石的体积，或者直接通过测量仪器得到宝石的体积。
作为一种优选的实施方式，宝石身份识别数据库包括预存刻面宝石的重量参数及几何结构特征参数信息的第一数据库及预存素面宝石的重量参数及几何结构特征参数信息的第二数据库；
其中，第一数据库包括：预存有关刻面宝石的长宽高信息的第一子数据库、预存有关刻面宝石的重量信息的第二子数据库、预存有关刻面宝石各个刻面的周长信息的第三子数据库、预存有关刻面宝石各个刻面的面积信息的第四子数据库、预存有关刻面宝石各个刻面与腰面的角度信息的第五子数据库以及预存有关刻面宝石的腰部波形信息的第六子数据库、预存有关刻面宝石类型的第七子数据库和预存有关刻面宝石琢型的第八子数据库；
第二数据库包括：预存有关素面宝石的长宽高信息的第一子数据库、预存有关素面宝石的重量信息的第二子数据库、预存有关素面宝石的表面弧度信息的第三子数据库以及预存有关素面宝石的表面积信息的第四子数据库、预存有关素面宝石种类的第五子数据库和预存有关素面宝石琢型的第六子数据库。
作为一种优选的实施方式，步骤(3)中进行数据比对时，首先判断待识别身份的宝石的类别；其次依据不同宝石类别测量其对应的重量参数及几何结构特征参数。此处所述的步骤(3)中进行数据比对时具体是指步骤(3)进行数据比对之前。可以理解的是，上述实施方式中也可以先测量待识别身份的宝石的重量参数及几何结构特征参数，再判断宝石的类别。
作为一种优选的实施方式，步骤中，“首先判断待识别身份的宝石的类别”，具体为确定宝石是刻面宝石还是素面宝石，当确定是素面宝石时，再进一步根据宝石的长宽高、宝石的重量、宝石表面的弧度、宝石的琢型、宝石的表面积以及宝石的3D模型进行比对判断，最终确定待识别身份的宝石的身份；当确定是刻面宝石时，再进一步根据宝石的长宽高、宝石的琢型、宝石的重量、宝石各个刻面的周长、宝石各个刻面的面积、宝石各个刻面与腰面的角度、宝石的腰部波形以及宝石的3D模型进行比对判断，最终确定待识别身份的宝石的身份。
作为一种优选的实施方式，当确认待识别身份的宝石的类别后，通过测量仪测量该宝石的重量及几何结构特征，并在数据库中对应选择适合宝石类别的第一数据库或是第二数据库，并将测得的该宝石的重量及几何结构特征与选定的第一或是第二数据库中的各个子数据库中的参数信息进行比对分析。
作为一种优选的实施方式，如图3所示，当确定待识别身份的宝石的类别
后，具体为确定宝石是刻面宝石还是素面宝石后，对应选择待识别身份的宝石的若干项宝石参数(第一条件)，将该若干项宝石参数与宝石身份识别数据库中预存的对应的参数信息进行对比计算，当在宝石身份识别数据库中找到唯一对应的宝石数据时，停止计算，得到待识别身份的宝石的身份；当在数据库中不能找到唯一对应的宝石数据时，得到包含有待识别身份的宝石的子数据库Ⅰ，再次选择待识别身份的宝石的若干项宝石参数(第二条件)，在所述子数据库Ⅰ中进行对比计算，当在所述子数据库Ⅰ中找到唯一对应的宝石数据时，停止计算，得到待识别身份的宝石的身份；当在子数据库Ⅰ中不能找到唯一对应的宝石数据时，得到包含有待识别身份的宝石的子数据库Ⅱ，再次选择待识别身份的宝石的若干项宝石数据(第三条件)，在所述子数据库Ⅱ中进行对比计算；重复上述过程，直至在子数据库N中找到唯一对应的宝石数据时，停止计算，得到待识别身份的宝石的身份；当未能找到唯一对应的宝石数据时，停止计算，未能得到待识别身份的宝石的身份。
本发明还提供一种用于识别宝石身份的系统，至少包括：
用于测定宝石重量的高精度天平，所述高精度天平至少应为十万分之一天平，即可读精度至少达到为0.01mg；
用于测定宝石几何结构特征的测量仪；
以及用于将测得的待识别身份的宝石的重量参数及几何结构特征参数与宝石身份识别数据库中的预存的宝石重量参数及几何结构特征参数信息进行比对，得出该待识别身份的宝石的身份的处理系统；
其中，如图4所示的处理系统包括：
控制模块M1，用于控制本系统进行运作；
判断分析模块M2，与控制模块M1通信连接，用于将待识别身份的宝石数据与宝石身份识别数据库中的宝石数据进行比对；
缓存模块M3，与控制模块M1通信连接，用于暂时存放测得的待识别身份的宝石的数据以及比对后得出的结果；
存储模块M4，与控制模块M1通信连接，用于存储待识别身份的宝石数据与宝石身份识别数据库中的数据进行比对的记录；
通信模块M5，与控制模块M1通信连接，用于调取宝石身份识别数据库中的宝石数据；
输入模块M6，与控制模块M1通信连接，用于选择性输入待识别身份的宝石的数据、选择所要查找的数据库以及对判断分析模块做设定；
显示模块M7，与控制模块M1通信连接，用于显示数据。
作为一种优选的实施方式，宝石身份识别数据库中的数据存放在本地存储设备中，本地存储设备与判断分析模块M2通信连接，本地存储设备设有与互联网上的宝石身份识别数据库进行更新的通信模块M5。
作为一种优选的实施方式，宝石身份识别数据库中的宝石数据存放在云计算中，并与互联网实现交互，所述的判断分析模块M2设有与互联网实现交互的通信模块M5。
其中，处理系统可以与测量仪进行集成，也可以通过数据传输设备将测量仪测得的数据传输至设置有处理系统的处理设备中。
由于目前还没有专门用于测定宝石几何结构特征的测量仪，因此，本发明中的测量仪可采用TSY周视多自由度定位刀具测量仪(如图8所示)或其他类似仪器，只要可以获取宝石几何结构特征的数据即可。
实际操作过程中，可以先确定待识别身份的宝石是刻面宝石还是素面宝石，确定后再确定其他参数。当本领域技术人员通过目测可以确定待识别身份的宝石的种类和宝石的形状时，通过输入设备，进行选择。当不能确定待识别身份的宝石的种类时，则不选定宝石种类；当不能确定待识别身份的宝石的形状时，则不选定宝石的形状；当这两者均不能确定的，则均不选择。
通过输入设备输入若干项区别度较高、且较易判断的指标，例如宝石的长宽高、宝石的重量和宝石的总体积，此为一个子数据库Ⅰ，当通过将待识别身份的宝石的参数与此子数据库Ⅰ中的宝石数据进行比对，能够找到唯一对应的宝石数据时，停止计算，得到待识别身份的宝石的身份。当在数据库中不能找到唯一对应的宝石数据时，再输入其它的待识别身份的宝石的参数，例如刻面的数量或者某一项或两项刻面的周长或面积或者某个刻面与腰面的角度，再次进行比对。逐步缩小数据库的范围，最终找到子数据库N中与待鉴定钻石数据相同的一条数据，直至找到唯一对应的宝石数据，则宝石身份识别工作完成。
当然，也可以直接将测得的待识别身份的宝石的数据与宝石身份识别数据库中的数据进行直接比对。
为了加速数据的寻找和比对的过程，提高对比计算的速率，可以先行将宝石根据形状、重量、种类和总体积等进行分类，再从子数据库中调取数据进行比对，节省了计算的时间。具体的说，宝石身份识别数据库中宝石的数据可以分为刻面宝石数据库和素面宝石数据库。
其中，刻面宝石数据库可以包括以下几个子数据库：外部尺寸数据库(包括宝石的长宽高)、形状分类数据库、重量分类数据库、宝石种类分类数据库和宝石总体积分类数据库。由于刻面的周长及刻面的面积数据量特别大，例如
58个刻面的钻石，其有58个刻面的数据，因此不适宜再分数据库，但是可以分为刻面数量分类数据库，例如58个、81个、101个、111个等刻面数据库。宝石的腰部波形相对来说也暂时很难分类。
素面宝石数据库可以包括以下几个子数据库：外部尺寸数据库(包括宝石的长宽高)、形状分类数据库、重量分类数据库、宝石种类分类数据库和宝石总体积分类数据库。当然，宝石表面的弧度、宝石的表面积也可以形成分类数据库。
其中，形状分类数据库可以根据宝石的形状进行再次分类，例如圆形、方形、椭圆形、心形、水滴形、马眼形等。
重量分类数据库可以根据宝石的重量级别进行再次分类，例如对于钻石来说，可以依照钻石行业的习惯划分，0.05ct以下的碎钻级别，0.05ct-0.22ct的小钻级别，0.23ct-1ct的中钻级别，1ct以上的大钻级别，10.8ct-50ct的特大钻级别，50ct以上的记名钻级别。其他宝石也可以根据其他重量等级进行分类。
宝石种类分类数据库可以根据宝石的种类进行再次分类，例如钻石、红宝石、蓝宝石、祖母绿、海蓝宝石、尖晶石等。
宝石总体积分类数据库可以根据宝石的总体积进行再次分类，可以参照重量分类进行。
实施例1
以刻面钻石为例加以说明，如图5-7所示，刻面钻石包括冠部刻面1、腰部刻面2以及亭部刻面3，其中，冠部刻面1包括台面11、星刻面12、冠部主刻面13以及上腰面14，亭部刻面3包括下腰面31、亭部主刻面32以及底面33。本实施例中所提供的刻面钻石，其冠部刻面1总数为33个，其中，台面11共1
个，星刻面12共8个，冠部主刻面13共8个，上腰面14共16个；其亭部刻面3总数为25个，其中，下腰面31共16个，亭部主刻面32共8个，底面33共1个。标准切工圆形的钻石一共有58个刻面，如果没有底尖的小刻面，就是57个刻面，这58或57个刻面共有7个形状。理论上讲，它们的位置、角度都是固定的，但是在实际加工过程中，由于钻石毛坯原料的形状、钻石毛坯原料的结构、加工时操作人员的手法等因素的影响，每个刻面的大小(边长)、表面积、空间角度都会有一定程度偏离理想状态，从而形成个体差异特征。对于素面宝石来说，宝石表面的弧度结合其他几何结构特征，也存在个体差异特性。这也就是本发明通过宝石本身的特征来确定宝石身份唯一性的理论依据。
将一待识别身份的刻面钻石置于TSY周视多自由度定位刀具测量仪(以下简称测量仪)中，测量该刻面宝石的每个刻面的面积和周长、刻面与腰面之间的角度、以及腰部波形。例如，针对图9冠部主刻面13中的第一主刻面131，通过测量仪，并在CAD的辅助下，测得其面积为13.61mm2，周长为4.7388mm；针对图10下腰面31中的第一下腰面311，通过测量仪，并在CAD的辅助下，测得其面积为35.31mm2和周长为7.3539mm；如图11所示，经测量仪测得上腰面14中的第一上腰面141与腰部的角度为24.66°，下腰面31中的第一下腰面311与腰部的角度为42.56°；图12为通过测量仪扫描得到的该刻面钻石的腰部波形图，从图12中可以看出，腰部最厚处达0.565mm、最薄处仅0.115mm。另外，宝石的长宽高可以采用分辨率为0.005mm以上的电子游标卡尺或其他工具进行测量。此外，通3D扫描的形式，可以得到宝石的3D模型，例如图13-14所示，其中，图14所示的刻面宝石的直径D为4.780mm，高H为2.987mm，其中，冠部高度h1为0.761mm，腰部厚度h2为0.162mm，亭部高度h3为2.064mm。
通过高精度天平得到此钻石的重量。由于测量数据的精确度很好，且数据多、数据组合独特，可以提高对于钻石唯一性判断的准确性。
将测量装置与控制器相连，将测得的数据直接传输至控制器上，也可以手动将测得的数据输入控制器内。
通过目测判断该待识别身份的宝石为刻面宝石，宝石种类是钻石，宝石形状为圆形，根据测得的宝石的重量，或者还可以增加一个钻石的体积，先行通过上述5个子数据库的交集得到一个子数据库Ⅰ，将待鉴定宝石的数据与此子数据库I进行对比，如不能找到唯一对应的宝石数据，再输入其他宝石数据，例如某个刻面的周长或面积或刻面与腰部的角度，进行计算比对，直至找到唯一对应的宝石数据，停止计算，得到待识别身份的宝石的身份；当未能找到唯一对应的宝石数据时，停止计算，未能得到待识别身份的宝石的身份。
由于钻石的腰部波形很难建立子数据库，因此，可以直接将腰部波形作为一项参数进行比对。但是目前由于腰部波形的形状在比对的过程中难度较大，因此，此项参数可以放在后面进行比对。
实际过程中，还可以根据子数据库I中的数据量，数据量大的话多输入几项宝石的数据，数据量小的话可以少输入一两项数据。
通过测得的宝石数据与数据库中的数据进对比，得到宝石的真实身份，此方法稳定、可靠，没有对宝石产生破坏，不会影响宝石的价值，且方法简单、操作方便、结果稳定、易于再现。
