技术领域
本发明涉及艺术品科学备案技术领域，特别是涉及一种艺术品定位取证安全备案的方法和系统。
背景技术
目前，艺术品市场繁荣兴盛，越来越多的投资者开始关注艺术品投资领域。然而，随着原创作品的不断问世，越来越多的仿品、赝品也随之产生，造假、作伪涉及艺术品收藏的各个门类，如字画、陶瓷、玉器、青铜器等。因此，艺术品的科学备案就显得尤为重要。
现有艺术品科学备案的常用方法包括：第一，获取艺术品的整体图像；第二，在艺术品上选择特征点，并通过便携式显微设备获取这些特征点的微观图像；第三，人工在艺术品的复制件或缩印件上标注这些特征点并人工记录这些特征点的位置和编号；第四，将艺术品的整体图像以及特征点的位置、编号与对应的微观图像存储在数据库中，另外，该数据库中还可以存储该艺术品的其它相关信息，例如艺术品名称、作者信息，创作时间等。
然而，上述备案过程中各步骤之间是在不同地点、不同时间由不同人分别完成的，尤其是第二步骤与第三步骤之间，由于特征点较多，人工记录的特征点的位置和编号与特征点的微观图像之间的对应关系极易出现错误，特别是微观图像的获取过程也缺少记录。因此，上述备案方法不够科学和严谨，不仅会导致备案的公信力降低，而且各步骤的分工独立进行也给取证备案带来安全隐患。
发明内容
本发明实施例所要解决的技术问题是提供一种艺术品定位取证安全备案的方法，能够对艺术品进行科学严谨的备案，提高备案的公信力和安全性。
相应的，本发明实施例还提供了一种艺术品定位取证安全备案的系统，用以保证上述方法的实现及应用。
为了解决上述问题，本发明公开了一种艺术品定位取证安全备案的方法，包括：采用拍摄装置获取艺术品的整体图像，记为第一图像；采用拍摄装置获取定位装置覆盖在艺术品上形成的图像，记为第二图像，其中，定位装置为一透明薄膜，且透明薄膜的表面具有至少一个定位区域和定位区域的标识信息； 采用拍摄装置获取显微摄像装置设置在定位装置表面上形成的图像，记为第三图像；启动显微摄像装置透过定位装置拍摄艺术品的微观图像，记为第四图像，第四图像中包含定位装置上定位区域的标识信息以及定位区域内艺术品的微观图像；将艺术品的第一图像、第二图像、第三图像和第四图像存入备案数据库。
本发明实施例还公开了一种艺术品定位取证安全备案的系统，包括拍摄装置、定位装置、显微摄像装置、存储装置；拍摄装置，用于获取艺术品的整体图像，记为第一图像；获取定位装置覆盖在艺术品上形成的图像，记为第二图像，其中，定位装置为一透明薄膜，且透明薄膜的表面具有至少一个定位区域和定位区域的标识信息；获取显微摄像装置设置在定位装置表面上形成的图像，记为第三图像；显微摄像装置，用于透过定位装置拍摄艺术品的微观图像，记为第四图像，第四图像中包含定位装置上定位区域的标识信息以及定位区域内艺术品的微观图像；存储装置，用于将艺术品的第一图像、第二图像、第三图像和第四图像存入备案数据库。
本发明实施例通过采用拍摄装置结合定位装置和显微摄像装置实现了艺术品备案过程中各操作步骤之间的连贯性，从而可以依次记录各操作步骤的图像，克服了现有备案过程中缺少操作过程记录的问题，并且，本方法通过图像记录的方式记载了艺术品上特征点的位置和序号及其与微观图像的对应关系，不再依靠人工记录，实现了精确的定位取证和准确的图像记录。该备案方法科学、严谨，提高了取证备案的公信力，也提高了备案过程中的安全性，使取证备案全过程拥有了可追溯、追责的依据。
本发明所要解决的技术问题还在于提供一种定位膜，能够精确定位并记录取证物上特征点的位置。
为了解决上述问题，本发明公开了一种定位膜，定位膜应用于对取证物的取证验证场景中，在取证验证时覆于取证物的表面上，定位膜为一透明薄膜，且透明薄膜的表面具有至少一个定位区域和定位区域的标识信息。进一步，定位区域的标识信息包括设置在定位区域一侧的第一标识符。进一步，定位区域的标识信息还包括设置在定位区域另一侧的第二标识符，且第一标识符与第二标识符呈预置缩放比例设置。进一步，定位区域的形状为椭圆形或矩形。进一步，定位区域的面积为10～15mm2。进一步，透明薄膜的表面还具有相互垂直的横线和纵线，定位区域位于横线和纵线的交叉位置。进一步，位于透明薄膜表面的最外围的横线上和/或位于透明薄膜表面的最外围的纵线上设置有刻度标识。进一步，位于透明薄膜表面的最外围的横线和位于透明薄膜表面的最外围的纵线在交叉处延伸呈十字线。进一步，定位区域的边界线、定位区域的标识信息、横线、纵线及刻度标识均印制在定位膜的靠近取证物一面的表面上。进一步，定位膜是厚度为0.1mm～0.5mm的聚对苯二甲酸类塑料PET膜。
进一步，每个定位区域是一组微观取证区，每组微观取证区包括一级取证区和设置在一级取证区内的二级取证区。进一步，每组微观取证区的外侧具有微观取证区的第一标识符。进一步，微观取证区内一级定位区的内侧具有微观取证区内一级定位区域的第二标识符，且第一标识符、第二标识符的大小呈预置缩放比例设置。进一步，微观取证区内二级取证区的内侧具有微观取证区内二级取证区的第三标识符，且第三标识符的大小与第二标识符的大小呈预置缩放比例设置。进一步，一级取证区的形状为椭圆形，和/或二级取证区的形状为矩形。进一步，定位膜的主体区域具有由相互垂直的横线和纵线形成的定位识别区，各组微观取证区均位于横线和纵线的交叉位置。进一步，定位识别区内设置有十字线。进一步，微观取证区和/或定位识别区的边界线在放大到预定倍数后边缘具有微观标识特征。进一步，定位膜的主体区域包括由各种点或线，或各种色彩或图形划分的大小不同的定位识别区域。进一步，定 位膜的主体区域外围设置有刻度线或标识或文字。
本发明实施例中，通过该具有定位区域和定位区域标识信息的透明定位膜，在对取证物进行取证时，可以直接将该定位膜覆盖于取证物表面，透过该定位膜直接获取取证物上特定区域的微观图像，其中，定位膜上的定位区域起到了直接在取证物上圈注特征区域并为其细节定位的的作用，同时又不会损坏取证物，而定位区域(微观取证区域)的标识信息可以在获取定位区域(微观取证区域)的微观图像时直接呈现在微观图像上，且可以唯一标识其对应的微观图像。该定位膜通过定位区域及定位区域的标识信息实现了对取证物上特征点、特征区域的精确定位和准确记录，解决了人工在复制件或缩印件上标注特征点、特征区域产生的标注不准确的问题，同时避免了人工记录、对照特征区域与微观图像等信息可能产生的数据记录错误的问题。而且，利用定位膜取证的整个过程只需将定位膜覆盖于取证物表面获取图像即可，无需再通过人工进行记录、对照、排序和标注等操作，大大简化了微观取证过程，提高了效率。同时，该定位膜覆盖在取证物上还可以起到保护取证物的作用。

具体实施方式
参照图1，示出了本发明的一种艺术品定位取证安全备案的方法实施例的步骤流程图，具体可以包括如下步骤：
步骤101，采用拍摄装置获取艺术品的整体图像，记为第一图像。
本发明实施例中，该拍摄装置具体可以是高清照相机或带有照相功能的摄像机等设备。以相机为例，该相机及三脚架的位置需保障艺术品画面完整且无任何几何畸变，摄影灯投射于艺术品的光线强度及均度符合翻拍要求，在调好焦距后按动快门，获得备案艺术品的完整图像，该图像记为第一图像。该拍摄装置在后续过程中可以根据艺术品尺寸及取证备案需求，维持拍摄装置的位置及焦距不变实施拍摄，或者适当移动位置进行调焦和拍摄，直至所有图像获取完成。
本发明实施例中的“第一图像”、“第二图像”、“第三图像”、“第四图像”等，仅仅为了描述方便，并非限定。
步骤102，采用拍摄装置获取定位装置覆盖在艺术品上形成的图像，记为第二图像。
在执行本步骤时，首先将定位装置覆盖在艺术品上，然后采用前述拍摄装置拍摄定位装置覆盖在艺术品上的图像，记为第二图像。该第二图像中可同时显示定位装置及其下面的艺术品。该第二图像可以包含拍摄装置在多个不同缩放倍数下拍摄的图像。
其中，定位装置可以是一张透明薄膜，且透明薄膜的表面具有至少一个定位区域和定位区域的标识信息。在使用该定位装置时，可以通过该定位装置上的定位区域在艺术品上圈定要备案的特征点，该特征点的位置和序号即可通过该定位区域的标识信息来记录，这些信息可以直接呈现在第二图像上。该过程通过图像记录的方式记载了特征点的位置和序号，不仅提高了记录的准确度，而且使该图像记录的内容更具说服力。
步骤103，采用拍摄装置获取显微摄像装置设置在定位装置表面上形成的图像，记为第三图像。
在本步骤中，首先，在保持定位装置与艺术品相对固定的情况下，将显微摄像装置放置在定位装置的上方，并使显微摄像装置的镜头对准定位装置的定位区域所圈定的特征点。然后，采用前述拍摄装置获取该显微摄像装置设置在定位装置表面的图像，记为第三图像。其中，该显微摄像装置可以是便携式显微设备，也可以是下文描述的取证验证仪等。该第三图像记录了使用显微摄像装置获取艺术品微观图像的过程，补充了现有备案过程中缺少的环节。该第三图像也可以包含拍摄装置在多个不同缩放倍数下拍摄的图像。
步骤104，启动显微摄像装置透过定位装置拍摄艺术品的微观图像，记为第四图像。
在本步骤中可以直接启动显微摄像装置，在确定放大倍数后，透过定位装置拍摄艺术品的微观图像，记为第四图像。该第四图像包含显微摄像装置在多个放大倍数下拍摄的图像，具体可以包括低倍放大倍数下拍摄的图像和高倍放大倍数下拍摄的图像。该第四图像中会同时包含定位装置和艺术品的信息，具体的，在一定放大倍数下如放大15倍获得的第四图像可以包含定位装置上定位区域的标识信息以及该定位区域内艺术品的微观图像。
该步骤通过图像记录的方式记载了特征点的微观图像及特征点所在定位区域的标识信息，通过与步骤102中获得的第二图像相结合，可以准确的定位特征点的位置和序号与其微观图像的对应关系，避免了现有备案方式中人工记录可能出现的错误，提高了备案的准确度。
步骤105，将艺术品的第一图像、第二图像、第三图像和第四图像存入备案数据库。
在获得上述所有图像后，即可将这些图像存储入备案数据库。另外，该备案数据库中还可以包括艺术品的名称、作者、创作时间、取证地点、取证备案相关人等信息。
本发明实施例通过采用拍摄装置结合定位装置和显微摄像装置实现了艺术品备案过程中各操作步骤之间的连贯性，从而可以依次记录各操作步骤的图像，克服了现有备案过程中缺少操作过程记录的问题，并且，本方法通过图像记录的方式记载了艺术品上特征点的位置和序号及其与微观图像的对应关系，不再依靠人工记录，实现了精确的定位取证和准确的图像记录。该备案方法科学、严谨，提高了备案的公信力，也提高了备案过程中的安全性。
上述方法可以应用于书画、陶瓷等多种艺术品的备案。
参见图2，为本发明的另一种艺术品定位取证安全备案的方法实施例的步骤流程图。
本实施例以书画艺术品为例，对整个备案过程进行描述。具体可以包括如下步骤：
步骤201，采用拍摄装置获取艺术品的整体图像，记为第一图像。
本实施例中，艺术品呈立式放置，具体可以是通过磁铁等固定件将艺术品固定在背板上，该背板是金属材质或带有磁性。该艺术品的立式放置方式非常方便于各步骤图像的获取，尤其对于尺寸比较大的艺术品，有利于特征点的选取和微观图像的拍摄。
在固定艺术品后，即可执行本步骤获取第一图像，该过程与前述步骤101类似，此处不再赘述。
步骤202，采用拍摄装置获取定位装置覆盖在艺术品上的图像，记为第二图像。
本实施例中，该定位装置具体可以是如图3所示，该定位装置上设置有16个定位区域11，该定位区域11的形状为椭圆形，每个定位区域11的边界一侧的外部设置有第一标识符12，内部设置有第二标识符11，第一标识符12和第二标识符11均可以选择阿拉伯数字进行标识。第一标识符12字符尺寸较大，用于肉眼识别不同的第一标识符12，以便于用相机将定位装置上的第一标识符12和定位区域11与艺术品的图像拍摄下来，成为日后验证找到特征点大概位置的依据；第二标识符11字符尺寸较小，用于在获取微观图像时，例如放大15倍时，可以清晰完整的识别第二标识符11，并便于显微摄像装置的显示屏同时显示该第二标识符11及相应的特征点的图像，此第二标识符11及其对应的微观图像资料将成为日后验证找到特征点精确位置的依据。该定位装置的表面还具有多条相互垂直的横线14和纵线15，定位区域11位于横线14和纵线15的交叉位置。上述横、纵线用于对艺术品上的特征点进行标识，可以具体辅助记录特征点的位置。
本步骤中，如图4所示，在确定出艺术品40上的特征点后，将该定位装置41的定位区域放置在特征点上，用磁铁等固定件将该定位装置41吸附在背板上，然后通过拍摄装置拍摄获得第二图像。
该第二图像可以包含拍摄装置在不同放大倍数下拍摄的图像。通过该第二图像中定位装置上的第一、二标识符及横、纵线可以清晰准确的确定出特征点的位置及编号。
另外，该定位装置上还可以设置有唯一标识信息，具体可以是定位装置的唯一编号，或者是使用该定位装置的备案人的信息。以便于在后续备案和司法鉴定过程中对该定位装置(证物)进行定位。
步骤203，采用拍摄装置获取显微摄像装置设置在定位装置表面的图像，记为第三图像，该第三图像中还记录有备案人和/或艺术品作者的图像。
该显微摄像装置上设置有磁性部件，通过其磁性部件与背板吸附固定，并使显微摄像装置的镜头对准定位装置的定位区域所圈定的特征点，如图5所示，定位装置41及艺术品40位于显微摄像装置51与背板之间。
当该书画作品具体为油画时，由于画布一般绷在有一定厚度的内框上，无法将整幅画直接贴覆在金属性或磁性背板上，此时可以将一块略大于定位装置面积的薄铁皮板放画布后面的与定位装置对应的位置，然后再用磁铁将定位装置及画布与铁皮板吸咐在一起，显微摄像装置也可以通过其磁性部件与该铁皮板吸附，这样就可以实施取证备案了。该铁皮板四角处可以设定位孔，以便于用螺丝等穿过该定位孔将铁皮板固定在木板和墙上，用于代替大面积的可磁性吸附的背板或墙。
本实施例中，在采用拍摄装置获取该显微摄像装置设置在定位装置表面的图像时，还可以让备案人和/或艺术品作者位于艺术品旁侧进行拍摄，获得第三图像，使第三图像同时记录备案人和/或艺术品作者的图像，从而使该艺术品的备案信息更加完备。而且，为后续备案和司法鉴定过程中提供了人证。
另外，该显微摄像装置上也可以设置有唯一标识信息，具体可以是显微摄像装置的唯一编号，或者是使用该装置的备案人的信息。以便于在后续备案和司法鉴定过程中对该显微摄像装置(证物)进行定位。
步骤204，启动显微摄像装置透过定位装置拍摄艺术品的微观图像，记为第四图像。
该步骤中，显微摄像装置可以透过定位装置拍摄艺术品在不同放大倍数下的微观图像，例如放大15倍和放大100倍的微观图像。
本实施例中，为了保证备案信息存储的安全性，防止数据篡改，在存储艺术品的图像信息时，可以分别执行步骤205和步骤206。
步骤205，将艺术品的第一图像、第二图像、第三图像和第四图像存入主服务器的备案数据库和备用服务器的备案数据库。
其中，主服务器与备用服务器可以设置在异地，且主服务器的备案数据库与备用服务器的备案数据库上可以设置有不同的访问权限。
通过将艺术品的备案信息存储在多个服务器上可以实现冗余保护，以防止一个服务器出现故障时不会造成艺术品备案信息的损毁。
另外，通过主、备服务器的异地设置，及访问权限设置，可以防止权限过于集中而可能产生的数据篡改问题。
步骤206，将艺术品的第一图像、第二图像、第三图像和第四图像进行硬件存储。
本步骤中还可以将艺术品的备案信息进行硬件存储，如制作光盘或存入硬盘等。而且可以将重要的硬件封存后存入公安系统、银行系统的安全托管业务部门。
这种艺术品定位取证安全备案的方法，是根据当代艺术品管理需求以及司法鉴定的精神原则创意设计的一个技术系统，它将精确的定位取证、准确的图像记录、多方+异地+物理隔离式的备案以及精准验证溶于一体，并开创了以整体拍摄+微观取证、物证+人证的新思路、新模式，从而使艺术品科学备案工作更科学，更严谨，更具公信力。
需要说明的是，对于方法实施例，为了简单描述，故将其都表述为一系列的动作组合，但是本领域技术人员应该知悉，本发明实施例并不受所描述的动作顺序的限制，因为依据本发明实施例，某些步骤可以采用其他顺序或者同时进行。其次，本领域技术人员也应该知悉，说明书中所描述的实施例均属于优选实施例，所涉及的动作并不一定是本发明实施例所必须的。
参照图6，示出了本发明一种艺术品定位取证安全备案的系统实施例的结构框图。
该系统具体可以包括拍摄装置61、定位装置62、显微摄像装置63、存储装置64。
其中，拍摄装置61，用于获取艺术品的整体图像，记为第一图像；获取定位装置62覆盖在所述艺术品上形成的图像，记为第二图像；获取显微摄像装置63设置在所述定位装置62表面上形成的图像，记为第三图像。定位装置62，为一透明薄膜，且所述透明薄膜的表面具有至少一个定位区域和所述定位区域的标识信息。显微摄像装置63，用于透过定位装置62拍摄艺术品的微观图像，记为第四图像，所述第四图像中包含所述定位装置上所述定位区域的标识信息以及所述定位区域内所述艺术品的微观图像。存储装置64，用于将所述艺术品的所述第一图像、所述第二图像、所述第三图像和所述第四图像存入备案数据库。
本发明实施例中，该系统通过采用拍摄装置结合定位装置和显微摄像装置实现了艺术品备案过程中各操作步骤之间的连贯性，从而可以依次记录各操作步骤的图像，克服了现有备案过程中缺少操作过程记录的问题，并且，本系统通过图像记录的方式记载了艺术品上特征点的位置和序号及其与微观图像的对应关系，不再依靠人工记录，实现了精确的定位取证和准确的图像记录。该系统的备案方法科学、严谨，提高了备案的公信力，也提高了备案过程中的安全性。
在另一实施例中，该第三图像中还可以记录有备案人和/或艺术品作者的图像。
另外，定位装置62和/或显微摄像装置63上均可以设置有唯一标识信息。
在另一实施例中，当艺术品为书画作品时，艺术品可以固定在背板上呈立式放置，显微摄像装置63可以通过其磁性部件与背板吸附固定，定位装置62及艺术品位于显微摄像装置63与背板之间。
在另一实施例中，存储装置64，具体可以用于将所述艺术品的所述第一图像、所述第二图像、所述第三图像和所述第四图像存入主服务器的备案数据库和备用服务器的备案数据库，其中，所述主服务器的备案数据库与所述备用服务器的备案数据库上设置有不同的访问权限。
在另一方式中，该存储装置64还可以是一用于存储该艺术品的所述第一图像、所述第二图像、所述第三图像和所述第四图像的硬件设备，如光盘或硬盘等。
对于装置实施例而言，由于其与方法实施例基本相似，所以描述的比较简单，相关之处参见方法实施例的部分说明即可。
以下介绍有关定位装置的实施例。在以下的描述中，定位装置与定位膜指代同一部件。
现有技术中，在对取证物取证时，如对艺术品或待鉴定物进行取证时，在缩小了若干倍的打印件或复印件上手工圈注特征点的位置，并人工对特征点位置进行标注记录的过程，一方面会由于缩放比例导致圈注的实际区域过大，不能准确定位到微观图像对应的特征区域，另一方面由于需要取证的特征点比较多，人工记录特征点的序号及对应位置和对应微观图像的方式极容易导致数据出错且效率较低。如此 不精准的微观结构取证位置标注方式，必然会对日后寻找、验证取证位置造成极大的困难。而且，该取证过程中特征点位置标注和微观图像获得是两个相互独立的环节，无法获得取证环节连贯的现场图像记录，使得取证资料的可靠性降低。因此，目前需要本领域技术人员迫切解决的一个技术问题就是：如何能精确定位并准确记录取证物上特征点的位置。
基于此，本发明实施例提供了一种定位膜，该定位膜应用于对取证物的取证验证场景中，如对艺术品或待鉴定物进行取证验证的场景，该定位膜用于在取证验证时覆于取证物的表面上，该定位膜为一透明薄膜，且透明薄膜的表面具有至少一个定位区域和定位区域的标识信息。
其中，该定位区域的个数可以有一个、两个或多个，定位区域的形状不限，可以是椭圆形或矩形或方形或圆形等，不同定位区域的形状可以不同。该定位区域用于界定获取微观图像的区域，该定位区域的尺寸和面积可以根据取证设备显示屏的状况及取证设备使用的微观图像的缩放比例推算获得，此处不做限定。该定位区域的边界在透明薄膜的表面可以是凸起的或凹陷的，也可以是印制在透明薄膜表面或埋入透明薄膜内部的。
定位区域的标识信息是用于唯一标识该定位区域的信息，该定位区域的标识信息设置在对应的定位区域的附近，具体可以设置在对应定位区域的周边或内部，每个定位区域的标识信息可以有一个或两个以上，例如，在定位区域的一侧设置有第一标识符，在另一侧设置有第二标识符，且第一标识符与第二标识符之间可以按照预置的缩放比例设置，其中“第一”、“第二”仅为区分不同的标识符，并非限定或特指。该标识信息可以是由数字或汉字或字母或它们的组合构成的字符，也可以是能唯一标识该定位区域的坐标信息，例如，各定位区域可以通过设置在定位膜表面的坐标轴或刻度线来唯一标识。
另外，该定位膜上还可以设置其它利于进行位置标识的信息，例如横纵线、刻度线，十字线等。具体请参见后续实施例的描述。该定位膜的厚度以不影响微观图像的获取为主，大小尺寸以便于帖服取证物为主，形状可以是长条形或方形等，材质以不易形变且耐高温等因素为主。其中，定位膜的厚度可以设置为0.1m～0.5mm，具体可以设置为0.3mm。定位膜的材质可以选择PET(polyethylene terephthalate，聚对苯二甲酸类塑料)膜。
本发明实施例中，通过该具有定位区域和定位区域标识信息的透明定位膜，在对取证物进行取证时，可以直接将该定位膜覆盖于取证物表面，透过该定位膜直接获取取证物上特定区域的微观图像，其中，定位膜上的定位区域起到了直接在取证物上圈注特征区域的作用，同时又不会损坏取证物，而定位区域的标识信息可以在获取定位区域的微观图像时直接呈现在微观图像上，且可以唯一标识其对应的微观图像。该定位膜通过定位区域及定位区域的标识信息实现了对取证物上特征点、特征区域的精确定位和准确记录，解决了人工在复制件或缩印件上标注特征点、特征区域产生的标注不准确的问题，同时避免了人工记录、对照特征区域与微观图像等信息可能产生的数据记录错误的问题。而且，利用定位膜取证的整个过程只需将定位膜覆盖于取证物表面获取图像即可，无需再通过人工进行记录、对照、排序和标注等操作，大大简化了微观取证过程，提高了效率。同时，该定位膜覆盖在取证物上还可以起到保护取证物的作用。
本实施例中，如图3所示，该定位膜上设置有16个定位区域11，该定位区域11的形状为椭圆形，长轴可以为5mm，短轴可以为3mm，该椭圆形的长轴沿竖直方向，短轴沿水平方向。在另一实施例中，该定位区域11的形状也可以为矩形，如图7所示，矩形的长为5mm，宽为3mm，矩形的长边沿竖直 方向，短边沿水平方向。
该定位区域11的面积可以为10～15mm2，具体可以选择10mm2。各定位区域的面积大小可以统一；若设定的标准面积为10mm2，那么该定位区域所圈定的任何局部其原大面积都是10mm2，都是在这原大面积为10mm2的局部范围内进行取证的，有此限定范围不仅便于日后精确地找到原取证物特征点位置实施验证，而且可以依据此定位区域的标准面积把握取证验证图像放大、缩小的级别，便于在还原程度一致的前提下比对取证物的图像与待鉴定物的验证图像的微观结构相似度。
如图3所示，每个定位区域11的边界一侧的外部设置有第一标识符12，内部设置有第二标识符13，具体可以设置在靠近边界上方或下方的位置，当然，该第一标识符12与第二标识符13也可以设置在边界的同侧，第二标识符13也可以设置在定位区域11的外部靠近边界的位置。第一标识符12和第二标识符13均可以选择阿拉伯数字进行标识，也可以采用不同的标识方式。第一标识符12字符尺寸较大，用于肉眼识别不同的第一标识符12，以便于取证者眼观选点操作，也便于用相机将定位膜上的第一标识符12和定位区域11与取证物的图像拍摄下来，成为日后验证找到特征点大概位置的依据；第二标识符13字符尺寸较小，用于在获取微观图像时，例如放大15倍时，可以清晰完整的识别第二标识符13，并便于取证设备的显示屏同时显示该第二标识符13及相应的特征点的图像，此第二标识符13及其对应的微观图像资料将成为日后验证找到特征点精确位置的依据。第一标识符12与第二标识符13可以呈预置的缩放比例设置。
该定位膜的表面还具有多条相互垂直的横线14和纵线15，定位区域11位于横线14和纵线15的交叉位置。最外围的横线14和最外围的纵线15上设置有刻度标识，在其它实施例中可以只在最外围的一条横线和/或最外围的一条竖线上设置刻度标识。而且，如图3所示，最外围的横线14和最外围的纵线15在交叉处延伸呈十字线。整个定位膜的中心位置还可以设置十字线。上述横、纵线及十字线用于对取证物上的取证部分进行标识和校正，可以具体辅助记录特征点、特征区域的位置。具体的，当对待鉴定物进行鉴定时，可以首先以中心十字线所处画面位置找到原微观取证的特征点的大体位置；然后利用定位膜上的定位区域11，定位区域11上下左右处的横、纵线，各横、纵线所形成的一个个方形区域，及外围的刻度标识准确定位出与取证物上相同的取证位置。最外围横、纵线交叉处延伸成的十字线以及各条线、各区域、各刻度，都可以综合针对待鉴定物上的图像获取位置进行较准，这不仅可以进一步找准微观图像对应的特征点的位置，而且还可以初步判断该待鉴定物是否是原取证物。
本实施例中，该定位膜为厚度0.3mm的透明PET膜。其透明材质覆盖在取证物上，既不影响微观结构取证验证，又能对此取证物起到安全保护作用。尤其是对珍贵的书画作品实施微观结构取证验证时，该用品覆盖在取证或验证的一定画面区域，或者整个画面区域，可以防止取证者、围观者的手触及画面，喷嚏、唾沫、烟灰、饮品等玷污画面、损伤画，以及取证设备及其它物品触碰画面，造成意外损失。
上述定位区域11的边界线、定位区域11的标识信息(第一、二标识符)、横线14、纵线15及刻度标识均印制在定位膜的靠近取证物一侧的表面上，以减少边界线、标识信息、横纵线等的磨损。另外，该定位膜上还可以印制其它信息，如定位膜及**专用等。
在使用该定位膜对取证物进行取证时，如图8所示，首先将该定位膜覆盖于取证物的表面，通过十字线、横、纵线及外围的刻度标识辅助记录定位膜的覆盖位置，然后将显微拍摄设备设置于定位区域11处，对定位区域11内的图像及第一标识符12、第二标识符13进行拍摄，然后调整放大倍数，对定 位区域11内的图像及清晰显示的第二标识符13进行显微拍摄。
当对待鉴定物进行鉴定时，与图8类似，依据通过十字线、横、纵线及外围的刻度标识辅助记录的定位膜的覆盖位置，将定位膜覆盖于待鉴定物上与取证物相同的位置，该过程可以根据位置是否相符粗略判断待鉴定物是否为之前的取证物，然后对定位区域11内的图像及第一标识符12、第二标识符13进行拍摄，按照对取证物显微拍摄时的相同放大倍数，对定位区域11内的图像及清晰显示的第二标识符13进行显微拍摄，最后对比相同定位区域11的微观图像，以对待鉴定物进行鉴定。
本实施例中的定位膜尺寸可以在1平方尺左右，可以应用于书画等平面艺术品的取证。对于圆柱型等瓷罐体上取证验证，可采用如图9所示的细长条型款式定位膜，而且为了卷曲方便可将定位膜的厚度适当减薄。若在盘状的器皿底部取证，可采用比掌心还小的小款式定位膜。定位膜的样式可以根据不同的应用场景进行设置或简化，如图10所示。
该定位膜实现了对取证物上特征点、特征区域的精确定位和准确记录，解决了人工在复制件或缩印件上标注特征点、特征区域产生的标注不准确的问题，同时避免了人工记录、对照特征区域与微观图像等信息可能产生的数据记录错误的问题。而且，利用定位膜取证的整个过程只需将定位膜覆盖于取证物表面获取图像即可，无需再通过人工进行记录、对照、排序和标注等操作，大大简化了微观取证过程，提高了效率。同时，该定位膜覆盖在取证物上还可以起到保护取证物的作用。
如图11所示，该定位膜可以总体尺寸宽不小于270mm，高不小于370mm。主体区域尺寸为250mm x 250mm，其中可以包括446个定位识别区，384个十字交叉点，2400条刻度线，各定位识别区、交叉点、刻度线均可沿其关连的纵横线伸延至主体区域四周的纵横线标识数字，从而以其表述清楚每一个定位识别区的具体方位。
该定位膜还具有图示标出的例如9个定位区域，每个定位区域对应一组微观取证区，每组微观取证区都以三级字号标注，统一排序。每组微观取证区的外侧都具有该微观取证区的第一标识符311。该第一标识符311应具体设置在本微观取证区外侧的近临处，其位置或上或下或左或右或左下或右下或左上或右上均可，如图11所示。
每组微观取证区域包括一级取证区312和设置在一级取证区312内的一个二级取证区313。在其它实施例中，该二级取证区313内还可以设置三级取证区，以此类推。一级取证区312的内周的一侧具有一级取证区312的第二标识符314，该第二标识符314具体可以设置在一级取证区312的内周位置，第二标识符314的大小与第一标识符311的大小呈预置缩放比例设置。二级取证区313的一侧具有二级取证区313的第三标识符315，该第三标识符315具体可以设置在二级取证区313的内周位置，可以直接设置在二级取证区域313的边界线上，如图7所示。第三标识符315的大小与第二标识符314的大小呈预置缩放比例设置。
第一标识符311、第二标识符314和第三标识符315均选择阿拉伯数字进行标识，也可以采用不同的标识方式。第一标识符311字符尺寸较大，用于肉眼识别不同的第一标识符311，以便于取证者眼观选点操作，也便于用相机将定位膜上的第一标识符311和定位区域、微观取证区域以及取证物的图像拍摄下来，成为日后验证找到微观取证区大概位置的依据；第二标识符314字符尺寸较小，用于在获取微观图像时，例如放大15倍时，可以清晰完整的识别第二标识符314，并便于取证设备的显示屏同时显示该第二标识符314及相应的特征点的图像，此第二标识符314及其对应的微观图像资料将成为日后验 证找到特征点精确位置的依据；第三标识符315字符尺寸更小，用于在获取微观图像时，例如放大40倍时，可以清晰完整的识别第三标识符315，并便于取证设备的显示屏同时显示该第三标识符315及相应的特征点的图像，此第三标识符315及其对应的微观图像资料也将成为日后验证找到特征点精确位置的依据。
该定位膜微观取证区的一级取证区域312的形状具体可以为椭圆形，该椭圆形的长轴沿竖直方向，短轴沿水平方向。该二级取证区域313的形状可以为矩形，矩形的长边沿竖直方向，短边沿水平方向。
该定位膜主体区域内的定位识别区可以是由相互垂直的横线和纵线交叉形成，各组微观取证区均位于横线和纵线的交叉位置。定位识别区内设置有十字线。另外，该定位识别区域也可以是由各种点或线，或各种色彩或图形划分而成的大小不同的区域，如图14所示。
而且，微观取证区和/或定位识别区的各种边界线在放大到一定倍数后，边界线的边缘清晰完整且具有微观标识特征。
另外，所述定位膜的主体区域外围设置有刻度线或标识或文字。例如，该定位膜上还可以印制其它信息，如***定位膜、**专用等，如图11、13所示。主体区域上下两方的所有文字笔划以及标识结构，也具有定位识别作用。而且各组定位识别区和各组微观取证区即可以在定位膜上按此设计分布，也可以按照一定规则分布。还有，该定位膜定位识别区、微观取证区的各标识信息、各横纵线及刻度标识均印制在定位膜的靠近取证物一侧的表面上，从而可以减轻各横纵线及标识信息的磨损。该膜可应用于各类平面物品的图像取证及其识别业务，尤其适用于书画科学备案及其识别工作。
下面介绍本实施例的若干优势。
1.该定位膜中由定位识别区和微观取证区形成的定位区具有标记画面结构并定位取证、比对识别之功能。将该透明膜覆盖在画面上，膜上的各纵横线、各方形区域、各椭圆形并长方形取证点及其序号、各处文字笔划及标识结构等与所覆盖的画面结构及细节相重合，便形成了特有的定位关系，而且具有了标记画面结构的作用。将此重合形成的图像拍摄备案，可成为日后识别该作品的依据一一验证时将定位膜覆盖在需要验证的画面位置上，并努力还原该膜上的图像(包括各条线、各区域、各文字笔划、各标识等)与画面各结构细节图像的重合关系，如果不存在明显差异，则可顺势找到9组微观取证区的精准位置。如果存在明显差异，则可断定其不是当时取证备案的原件。不过，此膜此法仅可识别手工临摹品，不适用于识别喷墨打印、珂罗版等现代科技复制品。
2.该定位膜的9组微观取证区均由椭圆形、矩形两种图形标注。椭圆形在外，略大，系一级取证区，可配合取证仪器镜头定位(在仪器屏幕显示中将其软件中的椭圆形与定位膜上的椭圆形相套合，从而使镜头精准地对向微观取证区)，并在较低放大倍率状态下定位取证或验证；矩形在椭圆形之内，略小，系二级取证区，可配合取证仪器在提升放大倍率状态下进一步取证或验证。毎组微观取证点编号均采用三个大小级别不同的同一数码标注。一级微观取证区椭圆形外的大字号数字可供人们的正常视力直接观看。椭圆形内的略小字号数字是一级取证区的取证编号，可在取证仪器屏幕上简接观看并提供拍摄备案。矩形内的略小字号数字是二级取证区的取证编号，也可在取证仪器屏幕上简接观看并提供拍摄备案。以此膜此法标记取证位置及序号，相当于在取证原件上精准标记取证点而又不触及画面，解决了人工圈注取证点、书写编号难免产生笔误的问题，降低了验证时寻找取证点的难度，以及无须动笔就可以准确记录的难题，并由此提高了取证验证工作的质量与效率。
3.该定位膜可以使取证验证的相关仪器与画面隔离，防止其直接触及作品画面，对画面有一定保护作用。尤其是对珍贵的书画作品实施微观取证验证时，该用品覆盖在取证或验证的一定画面区域，或者整个画面区域，其透明材质既不影响相关仪器对微观结构的取证验证，又能对被取证物起到安全保护作用。可以防止取证者、围观者的手触及画面，喷嚏、唾沫、烟灰、饮品等玷污或损伤画面，同时也可以防止相关设备及其它物品触碰画面，造成意外损失。
4.该定位膜釆用的印制工艺可以使微观取证区的椭圆形、矩形标识放大后呈现出不规则痕迹式的唯一性微观特征，以此配合该膜设置的专用人签名，可以对毎张膜的专用人及其业务实施有效的锁定管理。
以下介绍一种取证方法。
艺术品科学备案的常用的方法之一是获取艺术品的微观图像并进行备案。以字画为例，在获取其微观图像时，需要首先将字画平铺在桌台上，然后在字画上确定出数个特征点(取证点)，再采用显微设备将镜头对准特征点，调节所需的放大倍数后拍摄该特征点处的微观图像。但是目前还没有根据书画等艺术品微观图像取证验证特点与需求而设计的便携式显微设备。市场上虽然也有一些适用于其他领域的便捷式显微镜，但是当应用于艺术品科学备案时都存在一定的缺陷和问题。
由于获取微观图像时需要便携式显微镜与艺术品之间要具有非常稳定的相对位置关系，以便于便携式显微镜可以对预定拍摄区域进行精确定位。拍摄时轻微的移动或晃动就可能导致便携式显微镜的镜头偏离预定拍摄区域，导致拍摄的微观图像不是真实的预定拍摄区域的微观图片，进而会影响后续鉴定的正确度。
为了便于保持便携式显微镜与艺术品之间的稳定的相对位置关系，现有的各种便携式显微镜因其结构特点主要适用于平铺在桌台上的艺术品，这给艺术品微观图像的采集带来了诸多不便，尤其是对于尺寸较大的字画作品，较难获取其位于画面中央区域的特征点的微观图像。
因此，目前需要本领域技术人员迫切解决的一个技术问题就是：如何能保持获取微观图像时便携式显微设备与取证物之间稳定的相对位置关系，并简便的获取取证物上的微观图像。
本领域技术人员还要迫切解决的一个技术问题就是：如何能实现获取微观图像时便携式显微设备对预定拍摄区域的精确定位，并简便的获取取证物上的微观图像。
参见图15，为本发明实施例一种取证方法的流程图。
本方法的执行主体为取证验证仪，该方法应用于取证验证仪获取取证物的微观图像，该方法可以包括以下步骤：
步骤1101，当接收到用户的第一操作指令时，显示定位标识，该定位标识用于对取证物上的预定拍摄区域进行定位。
取证验证仪在拍摄取证物的局部的微观图像之前，可以先对取证物的局部图像(未放大)进行拍摄，然后再执行本实施例的步骤1101～1102。
在执行本步骤时，取证验证仪首先接收用户的第一操作指令，该第一操作指令具体可以是用户通过操作动作触发的按照指定倍数进行放大显示的指令，该用户的操作动作具体可以是调节控制放大倍数的按钮或滚轮等。
取证验证仪在接收到该第一操作指令后，会在图像显示界面中显示与该第一操作指令匹配的定位 标识，当然该图像显示界面中还会同时显示与该第一操作指令匹配的取证物局部图像。例如，该第一操作指令为放大15倍显示的指令，则该取证验证仪会显示与放大15倍匹配的定位标识，同时会按照现有方式显示该取证物上放大15倍后的图像。
上述定位标识用于对取证物上的预定拍摄区域进行定位，该定位标识与与覆盖在取证物上方用于辅助定位预定拍摄区域的定位膜上的定位区域相匹配。例如定位膜上的定位区域为椭圆形，则如图16所示，该取证验证仪显示的定位标识为椭圆形标记线，在放大指定倍数后，该取证验证仪显示界面中显示的椭圆形标记线与定位膜上的椭圆形定位区域恰好匹配或重合，从而可以很好的定位椭圆形内预定拍摄区域。再例如定位区域为矩形，则该定位标识为矩形标记线，在放大指定倍数后，该取证验证仪显示界面中显示的矩形标记线与定位膜上的矩形定位区域恰好匹配或重合，从而可以很好的定位矩形内预定拍摄区域。
在用户调整取证验证仪的位置，使得定位标识很好的对取证物上的预定拍摄区域进行定位后，执行步骤1102。
步骤1102，当接收到用户的第二操作指令时，对预定拍摄区域进行微观拍摄，获得微观图像。
用户可以通过按动快门等操作触发第二操作指令，该第二操作指令具体可以是拍摄指令，取证验证仪在接收到该第二操作指令后，即会对定位好的预定拍摄区域进行微观拍摄，从而获得该预定拍摄区域的微观图像。
在获得取证物的微观图像时，该步骤1101～1102可以多次重复执行，例如，当需要获得取证物的两级放大的微观图像时，可以首先执行一次步骤1101～1102获得第一级放大的微观图像，然后再重复一次步骤1101～1102获得第二级放大的微观图像，其中，两个第一操作指令对应的放大倍数不同，则对应的其中的定位标识也可以不同，例如，在获得第一级放大的微观图像时，第一操作指令对应放大15倍，则对应的定位标识可以是椭圆形标记线，在获得第二级放大的微观图像时，第二操作指令对应放大40倍，则对应的定位标识可以是矩形标记线。
取证验证仪获取微观图像时镜头是贴近取证物表面的，机身必然会遮挡取证者观察镜头是否对准取证位置的视线，特别是微观取证验证比对的有效面积往往在1平方毫米左右，不易查找具体位置，更不易让镜头精准对准该位置。该取证验证仪通过根据用户指令，显示用于对所述取证物上的预定拍摄区域进行定位的定位标识，使拍摄镜头可以根据该定位标识精准地对准取证物上的取证点或拍摄区域，实现了获取微观图像时对预定拍摄区域的精确定位，并可以非常简便的获取取证物上的微观图像。
在取证验证时，具体可以先将定位膜覆盖在取证物上，让定位膜上的椭圆形等定位区域定出取证位置(预定拍摄区域)，并以膜与画面相重合的图像以及椭圆形等定位区域作为取证验证仪镜头定位的依据，再在取证验证时在取证验证仪屏幕上显示定位标识去套合适量放大的定位膜上的椭圆形等定位区域，在此相套合的微调中便可以使取证验证仪镜头精准地对准取证点(预定拍摄区域)。
即便没有辅助定位的定位膜，该取证验证仪也可以通过该定位标识与取证物图像的重合或交叉位置来实现对取证物上预定拍摄区域的定位，提高获取微观图像时对预定拍摄区域的定位的精确度。
另外，该取证仪通过对取证物上定位区域定位的位置进行放大拍摄，还可以辅助工作者辨识取证物上的喷墨打印点，以辨别取证物是否是现代科技复制品。
参见图17，为本发明实施例另一种取证方法的流程图。
本实施例中除了包括上述步骤1101～1102之外，还可以进一步包括：
步骤1301，获得微观图像的描述信息。
本步骤中，该取证验证获得的微观图像的描述信息具体可是：接收用户输入的图像信息；或获取仪器标识信息；或通过GPS模块获取微观图像的拍摄时间地点信息。还可是上述信息中的任意组合。
其中，如图18所示，用户输入的图像信息可以是用户直接在拍摄的微观图像的一侧或固定区域输入的图像信息，该图像信息可以是由用户(取证人等)采用中英等多种文字输入的取证物的作者、作品、备注等基本信息中的一个或任意组合。仪器标识信息可以是该取证验证仪的唯一仪器编号。通过GPS模块获取微观图像的拍摄时间地点信息可以是由取证验证仪通过互联网与内置的GPS模块自动获取的拍摄微观图像时的时间(包括年月曰、几时几分)和地点信息，该时间和地点信息可以在取证验证仪屏幕上的指定区域自动显示。
步骤1302，将微观图像及微观图像的描述信息合成为图文数据。
在获取微观图像及上述描述信息后，即可将微观图像及描述信息合成为图文数据，具体可以按照预置的图文模板对图像和描述信息进行组合或拼接。
通过上述步骤，该取证验证仪可以实现以下功能：在取证验证现场以仪器获取微观图像过程中，由取证验证者本人面对具体作品具体部位的取证验证点，及时将基本文字信息填写在取证验证的图像中，如图18所示，可以形成一个文图结合于一体的完整图像数据，省去文图分离的书写环节。这样即可以保障该数据无误，又可以增强该数据的公信力与证明力。
如图18所示，在取证验证仪屏幕上显示出本仪器的唯一编号，可将该仪器及其专用人取证验证具体操作获得的图像连接在一起，从而便于锁定具体机构具体工作人员的具体业务。这样既便于对具体业务具体工作人员实施管理，又可以增强该数据的公信力与证明力。
如图18所示，利用互联网与GPS模块在取证验证仪屏幕上自动显示出准确的取证时间(包括年月曰、几时几分)和取证地点，并与取证验证的以上各项图文信系溶为一体锁定存储，这样可以使数据更加完整，防止日后或异地补填文字出现失误或人为篡改数据，从而增强该数据的公信力与证明力。
取证验证仪将以上各信息汇聚拍摄成一个完整的图像信息实施备案。从而避免了临时编号与人工书写所容易出现的失误，确保了信息的可靠性与完整性。
本实施例中，该方法还可以进一步包括以下步骤：
步骤1303，将仪器标识信息及微观图像的拍摄时间按照预置规则合成为图文数据的标识信息。
本实施例中，该取证验证仪还可以提取上述仪器的标识信息及微观图像的拍摄时间，然后按照预置规则合成该图文数据的标识信息，例如将图18中显示的本机编号及取证时间相串接形成的数据编号作为该图文数据的标识信息。通过该图文数据的标识信息可以直观的获得该图文数据是在那一台仪器在何时获得的数据。这样无论是在全国各地还是在世界各国，也无论有多少台仪器获得多少数据存入数据库，其数据编号用于不会重复，十分便于数据查找和追溯。
步骤1304，将图文数据及图文数据的标识信息进行存储和/或异地传输。

另外，上述定位标识可以为椭圆形标记线或矩形标记线，其中，所述椭圆形标记线与覆盖在所述取证物上方用于辅助定位所述预定拍摄区域的定位膜上的椭圆形定位区域相匹配；所述矩形标记线与所述定位膜上的矩形定位区域相匹配。
上述各模块的具体实现过程请参见前述方法实施例的描述，此处不再赘述。
以下仍将结合图21-23介绍取证验证仪。
现有技术中，为了保证在拍摄过程中保持便携式显微镜不发生移动、晃动，取证人需要手持便携式显微镜使其尽量贴紧取证物，才可保证拍摄时减少移动和晃动，如果应用于其它场景，如立面放置的取证物，则在取证人手持便携式显微镜悬浮操作时，极易发生移动或晃动，进而导致微观图像的错位、失真和模糊，而且取证人在该过程中无法进行记录等其它操作，对取证带来不便。特别是便携式显微镜对平铺在桌台上的尺寸较大的取证物进行微观取证时，不便于获取其位于画面中央区域的特征点的微观图像。由此可见，现有的便携式显微镜并不能方便的获取取证物的有效微观图像，操作效率较低。为此，提供一种取证验证仪，能够保持获取微观图像时便携式显微设备与取证物之间稳定的相对位置关系，并简便的获取取证物上的微观图像。
基于此，本发明实施例公开了一种取证验证仪，如图21所示，本实施例中，该取证验证仪包括 上壳体11、下壳体12和夹持在上壳体11与下壳体12之间的支撑件13，支撑件13上设置有显微摄像部件。其中，下壳体和/或支撑件上设置有可与取证物的背板吸附的磁性部件。该取证验证仪中，可以只在下壳体或只在支撑件上设置磁性部件，也可以在下壳体和支撑件上均设置磁性部件，磁性部件的具体位置可以根据需要设置。其中，下壳体的尺寸可以大体与支撑件的尺寸相同，下壳体可以与支撑件上的磁性部件对应的区域设置孔洞，以减少下壳体对磁性部件磁力的削弱。下壳体的尺寸也可以比支撑件的尺寸略小，以裸露出支撑件上的磁性部件。
磁性部件具体可以是磁场强度较强的磁铁，如环形磁铁等，磁性部件的数量可以为一个或多个，例如，下壳体上设置一个磁性部件，支撑件上设置两个磁性部件等。每个磁性部件可以包含多个磁铁，例如多个叠放在一起的磁铁，通过磁铁的个数可以改变磁场强度。
另外，支撑件上设置的显微摄像部件可以与现有便携式显微镜的显微摄像部分结构相同，具体可以包括设置在支撑件一端的镜头元件，设置在支撑件上的镜头元件的控制元件、供电元件，及设置在上壳体上且与控制元件连接的显示元件。控制元件用于控制镜头元件并通过镜头元件获取图像，存储图像等，供电元件用于为整个显微摄像部件供电，显示元件用于显示图像。其中，上壳体上可以开有通透的槽，该槽的尺寸正好可以容纳显示元件中显示屏的尺寸。具体请参照后续实施例的描述。
上壳体、下壳体和支撑件可以均采用塑料材质，相互之间可以通过螺栓固定或卡接固定，或注塑成型等方式固定。
如图21所示，显微摄像部件可以包括显示屏14(显示元件)、电路板15(控制元件)、电源板16、电池17(两者构成供电元件)、镜头18、调焦旋钮19(两者构成镜头元件)。电路板15上连接有感光芯片151。另外，镜头18上可罩有透明罩181，以保护镜头18。
上壳体11上可以开有用于容纳显示屏14的孔。
下壳体12的中央位置可以设置有第一磁性部件121，具体的，如图21、图22所示，下壳体12的中央位置具有第一凸起122，第一凸起122的端面具有第一凹槽，第一磁性部件121位于第一凹槽内。该第一磁性部件121具体可以是环形磁铁，该环形磁铁可以通过穿过该环形中心的螺栓固定在下壳体12上。为了避免第一磁性部件121对电路板15的影响，该第一磁性部件121在靠近下壳体12的一面可以设置有防磁部件，该防磁部件可以与第一磁性部件121固定在一起。
支撑件13的一端可以对称设置有两个第二磁性部件131，第二磁性部件131的尺寸可以略小于第一磁性部件121的尺寸。具体的，如图21，图22所示，在镜头18的两侧可以对称设置有两个第二凸起132，每个第二凸起132的端面具有第二凹槽，第二磁性部件131位于第二凹槽内。该第二磁性部件131可以包括一个或多个环形磁铁，该环形磁铁可以通过穿过该环形中心的螺栓固定在支撑件13上。环形磁铁之间还可以设置有垫圈。通过增减环形磁铁的个数及加减环形磁铁之间的垫圈可以调整该第二磁性部件131的磁场强度。
另外，支撑件的侧面上，例如支撑件13靠近镜头18一侧的侧面上还可以设置有用于定位的标识线133。该标识线133可以有三条，分别与取证物上的特定位置相对应，以便于对该取证验证仪进行准确定位。
该支撑件13上还可以开设有MicroUSB口以对电池17进行充电及已拍摄图像的存储。该取证验证仪内也可以设置有无线通信模块，已拍摄图像也可以通过无线通信模块进行传输。
在使用该取证验证仪时，如图23所示，首先根据取证物31上特征点的位置，利用标识线133对取证验证仪32进行准确定位，通过第一磁性部件121和第二磁性部件131将取证验证仪32吸附在取证物31的背板上，然后调节调焦旋钮19调整镜头18的放大倍数，在确定放大倍数后，通过显示屏14上的触摸按钮对特征点的微观图像进行拍摄。
在使用该取证验证仪时，取证物覆盖在背板上，该背板可以是金属板或磁性板等，该背板可以是水平放置的，也可以是竖立的，还可以与水平面呈某一夹角。当该取证验证仪放置于该取证物特征点的上方时，该取证验证仪可以通过下壳体和/或支撑件上的磁性部件与取证物的背板磁性吸附，进而可以使取证验证仪稳固的放置在取证物上，显微摄像部件的镜头即可对取证物上的特征点进行微观图像的观察和拍摄，而且拍摄时无需取证人手持仪器。尤其对于立面放置的取证物，无论取证物的尺寸如何，都可以通过该取证验证仪方便的获取取证物上所有特征点的微观图像。
本发明实施例的取证验证仪不仅可以通过显微摄像部件完成对取证物微观图像的获取，而且通过设置磁性部件使得取证验证仪可以稳固的吸附在取证物的背板上，从而在拍摄图像时可以与取证物形成固定的相对位置关系，保证了微观图像的清晰准确、真实有效，而且在拍摄过程中无需取证人员手持仪器操作，简化了获取微观图像的过程，提高了取证效率。而且，该取证验证仪改变了现有便携式显微镜不能稳固拍摄的局限，通过磁性部件，该取证验证仪可以稳固地对立式放置的取证物进行微观图像的获取，该方式既便于在大尺寸取证物上的中央区域获取微观图像，又方便记录获取微观图像的过程。当应用于字画作品的取证时，还可以让作品整体画面的翻拍工作与该微观图像取证工作使用同一个场地，利用同一次画面定位、光线调整，这种连贯性操作可以一举多得，既可以节省工作时间，又可以节省工作空间，还可以节省业务设置成本。
本说明书中的各个实施例均采用递进的方式描述，每个实施例重点说明的都是与其他实施例的不同之处，各个实施例之间相同相似的部分互相参见即可。各实施例可以彼此结合形成新的实施例，例如，图21和图22的取证验证仪也可包括图19或图20的结构，即取证验证仪还可包括显示控制模块501及拍摄控制模块502等，拍摄控制模块502可以控制显微摄像器件或是显微摄像器件的一部分。
以下介绍一种磁性微观镜。
图24和图25为本实用新型的磁性微观镜的结构示意图，如图所示，本实用新型的磁性微观镜包括镜体100；放大器件200，其固定地或可拆卸地安装在镜体100的顶端；顶部光源300，其包括一个或多个照明器件，安装在镜体100的内部，位于放大器件的下方，用于朝下方照射；以及一个或多个磁性部件400，其安装在镜体100的底部。镜体100可以为各种合适的中空外壳，例如截面为矩形、圆形等。放大器件200可以为任何可放大成像的元件，例如放大镜、显微镜等。磁性部件400可以以任何合适的方式安装在镜体100上，例如，可采用焊接、粘接、嵌入方式、螺接、用紧固件连接等。照明器件可以采用LED等各种灯源。
该磁性微观镜可以放置在取证物上，放大器件对取证物的特征点进行放大成像，自带照明器件，保证了不受外界光源的影响，在任何条件下均可在放大器件上形成清晰的微观图像，设置磁性部件，磁性微观镜可以吸附在取证物的磁性背板上，从而在获取图像时可以与取证物形成固定的相对位置关系，保障了微观图像的真实有效，而且在取证过程中无需取证人员一直手持仪器，简化了获取微观图像的过程， 提高了取证效率，尤其能有效针对立式取证物进行取证。
此外，如图25所示，还可以包括侧光光源500，其包括一个照明器件，安装在镜体100的内壁上，位于顶部光源300的下方，用于从一侧发射侧光。对于油画等肌理有起伏的艺术品，侧光光源500的效果是显著的，利用侧光光源500，可以观察到肌理的起伏，利于取证和验证。
放大器件200可以可拆卸地安装在镜体100的顶端，这样方便更换不同放大倍数的放大器件，还利于从顶部进入镜体内部，进行其他部件的安装、维修等。可以利用各种合适的方式实现该可拆卸设置。
顶部光源300的控制开关300a和侧光光源500的控制开关500a是独立的，它们可以根据需要选择性地开启，例如，顶部光源300可是常开的，便于常态观察，侧光光源500在一些场合可以单独开启。控制开关可以设置在镜体的任何合适的位置，例如镜体的内表面或外表面上。控制开关可以采用简单的按钮方式，也可以采用旋钮方式，通过旋转开关实现照明控制等。
磁性部件400可以采用任何适当的结构。如图3所示，磁性部件400可以包括堆叠的至少一个磁铁410以及至少一个非磁性垫圈420，非磁性垫圈相对于磁铁的位置能调节。这样，通过改变非磁性垫圈420的位置，能够改变整个磁性部件的磁力，进而改变整个磁性微观镜的吸附力度。例如在图示的状态下，将两个非磁性垫圈420改为均位于最下方磁铁之下，也可以将它们位于最上方磁铁的上方等等。
如图3所示，紧固件430可以穿过磁铁410和非磁性垫圈420以固定磁铁410和非磁性垫圈420。紧固件430可以是任何合适的器件，诸如螺丝等。
磁性部件400可以安装在镜体100上任何合适的位置。如图25所示，磁性部件400可以安装在镜体100的底面的安装槽中，这样便于安装和拆卸。例如，拆卸后可以根据所需吸附力度来调节非磁性垫圈420和磁铁410之间的相对位置，调节好后再将它们安装就位。
在一实施例中，还可以包括挡光器件，其可以安装在镜体100的内侧，位于放大器件200和顶部光源300之间。这样，可以避免光线投射向放大器件方向，影响取证人员观察或者影响拍摄装置拍摄。例如，如图25所示，挡光器件可以包括简单的挡光圈600，利用其物理结构实现挡光。
如图25所示，顶部光源300可以安装在挡光圈600的底部。这样可以用简单的结构实现顶部光源300的安装，简化了整个装置的结构。
如图25所示，镜体100底部的四周边缘上可以具有定位标尺。这样，该装置单独即可实现在取证物上的定位，可以无需下述的定位膜的辅助。
此外，蓄电池700可以安装在镜体的内侧，为顶部和侧光光源提供电源，可以设置USB接口700a等对蓄电池700进行充电。当然，也可以采用一次性电源。
还可以包括与放大器件200配合使用的功能镜片，所述功能镜片包括偏振镜片、滤色镜片和/或柔光镜片。功能镜片与放大镜片叠加在一起，或者功能镜片与放大镜片分开。这样，可以确保被观察物的成像质量。
如图25较佳示出的所示，镜体100底部的边角被导圆，在每个边角上设置倒三角的定位角标100a。这样，在放置到取证物或定位膜上后，不会划伤取证物或定位膜。利用定位角标，可以实现精确定位在取证物上，或者与定位膜配合使用定位效果更佳，此时定位角标可以对准定位膜上的定位区域或刻度等。当然，镜体100顶部的边角也可以导圆。
在本说明书的描述中，“顶部”和“底部”等并不用于将相应部件限制为图示的位置。除非另有明确的规 定和限定，术语“安装”、“连接”、“固定”等术语应做广义理解，例如，“连接”可以是固定连接，也可以是可拆卸连接，可以是直接相连，也可以通过中间媒介间接相连。对于本领域的普通技术人员而言，可以根据具体情况理解上述术语在本实用新型中的具体含义。“内侧”是相对于“外侧”而言的，即在镜体的中空腔的内部。
本发明实施例是参照根据本发明实施例的方法、终端设备(系统)、和计算机程序产品的流程图和/或方框图来描述的。应理解可由计算机程序指令实现流程图和/或方框图中的每一流程和/或方框、以及流程图和/或方框图中的流程和/或方框的结合。可提供这些计算机程序指令到通用计算机、专用计算机、嵌入式处理机或其他可编程数据处理终端设备的处理器以产生一个机器，使得通过计算机或其他可编程数据处理终端设备的处理器执行的指令产生用于实现在流程图一个流程或多个流程和/或方框图一个方框或多个方框中指定的功能的装置。
这些计算机程序指令也可存储在能引导计算机或其他可编程数据处理终端设备以特定方式工作的计算机可读存储器中，使得存储在该计算机可读存储器中的指令产生包括指令装置的制造品，该指令装置实现在流程图一个流程或多个流程和/或方框图一个方框或多个方框中指定的功能。
这些计算机程序指令也可装载到计算机或其他可编程数据处理终端设备上，使得在计算机或其他可编程终端设备上执行一系列操作步骤以产生计算机实现的处理，从而在计算机或其他可编程终端设备上执行的指令提供用于实现在流程图一个流程或多个流程和/或方框图一个方框或多个方框中指定的功能的步骤。
还需要说明的是，本文中诸如第一和第二等之类的关系术语仅仅用来将一个实体或者操作与另一个实体或操作区分开来，而不一定要求或者暗示这些实体或操作之间存在任何这种实际的关系或者顺序。而且，术语“包括”、“包含”或者其任何其他变体意在涵盖非排他性的包含，从而使得包括一系列要素的过程、方法、物品或者终端设备不仅包括那些要素，而且还包括没有明确列出的其他要素，或者是还包括为这种过程、方法、物品或者终端设备所固有的要素。在没有更多限制的情况下，由语句“包括一个……”限定的要素，并不排除在包括所述要素的过程、方法、物品或者终端设备中还存在另外的相同要素。
以上实施例的说明只是用于帮助理解本发明的方法及其核心思想；同时，对于本领域的一般技术人员，依据本发明的思想，在具体实施方式及应用范围上均会有改变之处，综上所述，本说明书内容不应理解为对本发明的限制。
