Description
本发明涉及文物修复领域，尤其涉及一种瓷器表面裂纹修复鉴定系统。
文物修复大体可分为三类，即研究修复、展览修复和商业修复。三种修复虽在目的、方法上存在差别，但在保持文物的原质、原味上仍是相同的。
商业修复的要求则更高，需把破损的器物恢复成原来的形状和颜色，使其色彩、纹饰和质感呈现出完好的视觉效果。
古陶瓷修复一般须经检测、清洁、加固、粘接、补配等十多道工序，而作色作旧是最后一道工序，也是一项非常细致的工作，不仅要求修复员有纯熟的技巧，更要对色彩具有敏锐的观察能力和分析能力。修复者需有较高的艺术修养和美术功力作为支撑，否则会失掉文物的古韵。
然而，在现有技术中对待修复瓷器的裂纹检测和裂纹修复完全依靠文物修复师的个人经验进行，缺乏严谨的参考数据。
发明内容
本发明至少具有以下两个重要发明点：
(1)对待修复瓷器的表面裂纹的分裂程度进行现场解析，以对分裂严重的裂纹作为重点修复区域进行高亮红色显示，分裂不严重的裂纹作为非重点修复区域进行高亮蓝色显示；
(2)分别基于瓷器的成像特征以及裂纹的灰度分布范围对当前修复 场景的成像图像进行瓷器和表面裂纹的检测和定位。
根据本发明的一方面，提供了一种瓷器表面裂纹修复鉴定系统，所述系统包括：
修复鉴定机构，与裂纹识别设备连接，用于对每一个裂纹区域执行以下处理：确定所述裂纹区域占据瓷器子图像的面积比例，当所述面积比例大于等于预设比例阈值时，将所述裂纹区域作为需要修复的目标区域，当所述面积比例小于所述预设比例阈值时，将所述裂纹区域作为不需要修复的目标区域；
高亮显示设备，与所述修复鉴定机构连接，用于显示所述瓷器子图像，并在所述瓷器子图像中对需要修复的目标区域进行高亮红色显示，对不需要修复的目标区域进行高亮蓝色显示；
枪型拍摄设备，用于面对表面分布裂纹的待修复瓷器所在环境进行现场拍摄操作，以获得对应的修复环境图像；
反差保留设备，与所述枪型拍摄设备连接，用于对接收到的修复环境图像执行图像中颜色或明暗反差明显的两部分的交界处保留下来的处理，以获得并输出相应的反差保留图像；
实时增强设备，设置在所述反差保留设备附近，与所述反差保留设备连接，用于对接收到的反差保留图像执行图像频域增强处理，以获得并输出相应的实时增强图像；
锐化处理设备，与所述实时增强设备连接，用于对接收到的实时增强图像执行基于USM滤镜的锐化处理，以获得并输出相应的即时锐化图像；
裂纹识别设备，用于接基于瓷器成像特征从所述即时锐化图像中搜索出相应的瓷器子图像，基于预设裂纹上限灰度阈值和预设裂纹下限灰度阈值识别出所述瓷器子图像内的多个裂纹像素点，将多个裂纹像素点进行去孤点处理后拟合成一个或多个裂纹区域。
本发明的瓷器表面裂纹修复鉴定系统操作简单、运行可靠。由于采用了可靠的电子鉴定模式对瓷器表面裂纹进行有效鉴定，从而为后续的瓷器表面裂纹修复提供了针对性的参考数据。
下面将对本发明的瓷器表面裂纹修复鉴定系统的实施方案进行详细说明。
瓷器是由瓷石、高岭土、石英石、莫来石等烧制而成，外表施有玻璃质釉或彩绘的物器。瓷器的成形要通过在窑内经过高温(约1280℃～1400℃)烧制，瓷器表面的釉色会因为温度的不同从而发生各种化学变化，是中华文明展示的瑰宝。
凡是用瓷土烧制而成的器物就叫瓷器。但当今对瓷器的具体定义，还没有取得统一的意见。一般人认为，必须具备以下几条才能称之为瓷器：
第一，瓷器的胎料必须是瓷土的。瓷土的成分主要是高岭土和化妆土，并含有长石、石英石和莫来石成分；含铁量低。经过高温烧成之后，胎色白，具有透明或半透明性，胎体吸水率不足1％，或不吸水。
第二，瓷器的胎体必须经过1200℃～1300℃的高温焙烧，才具备瓷器的物理性能。各地瓷土不同，烧成温度也有差异，要以烧结为准。
第三，瓷器表面所施的釉，必须是在高温之下和瓷器一道烧成的玻璃质釉。
由于古代瓷器的珍贵性，即使是破碎的古代瓷器，通过有效、可靠的文物修复下，仍具有较高的经济价值，然而，当前的瓷器表面裂纹修复完全拼接人工经验进行，无法实现科学、准确的裂纹鉴定和裂纹处理操作。
为了克服上述不足，本发明搭建了一种瓷器表面裂纹修复鉴定系统，能够有效解决相应的技术问题。
根据本发明实施方案示出的瓷器表面裂纹修复鉴定系统包括：

高亮显示设备，与所述修复鉴定机构连接，用于显示所述瓷器子图像，并在所述瓷器子图像中对需要修复的目标区域进行高亮红色显示，对不需要修复的目标区域进行高亮蓝色显示；
枪型拍摄设备，用于面对表面分布裂纹的待修复瓷器所在环境进行现场拍摄操作，以获得对应的修复环境图像；

实时增强设备，设置在所述反差保留设备附近，与所述反差保留设备连接，用于对接收到的反差保留图像执行图像频域增强处理，以获得并输出相应的实时增强图像；
锐化处理设备，与所述实时增强设备连接，用于对接收到的实时增强图像执行基于USM滤镜的锐化处理，以获得并输出相应的即时锐化图像；
裂纹识别设备，用于接基于瓷器成像特征从所述即时锐化图像中搜索出相应的瓷器子图像，基于预设裂纹上限灰度阈值和预设裂纹下限灰度阈值识别出所述瓷器子图像内的多个裂纹像素点，将多个裂纹像素点进行去孤点处理后拟合成一个或多个裂纹区域。

ASIC芯片技术所有接口模块(包括控制模块)都连接到一个矩阵式背板上，通过ASIC芯片到ASIC芯片的直接转发，可同时进行多个模块之间的通信；每个模块的缓存只处理本模块上的输入输出队列，因此对内存芯片性能的要求大大低于共享内存方式。总之，交换矩阵的特点是访问效率高，适合同时进行多点访问，容易提供非常高的带宽，并且性能扩展方便，不易受CPU、总线以及内存技术的限制。大部分的专业网络厂商在其第三层核心交换设备中都越来越多地采用了这种技术。
