Description

无色差的影像扫描、显示及照明系统 技术领域
本发明涉及影像扫描技术领域，特别是涉及一种无色差的影像扫描、显示及照明系统。
背景技术
信息化的时代已经来临，以往以传统人工运作的方式，将逐渐被信息化的应用所取代，例如假牙建立模型及后续制作，以往每一个步骤都需要牙医师及专业牙技师人工完成、又衣服打样比色及后续制作，也需要人工及经验累积、再者鞋子可能在美国设计，亚洲打样，然后再送回美国确认等，这些人工的作业，实体样品的确认，因而产生了距离、时间及效率上的限制。
以假牙制作为例，现有技术的假牙制作，是先由牙医师在诊所以人工进行牙模建模、色卡或齿板的人工对色，然后以物流方式将牙模运送到牙技所，并通知牙技所比色后的色卡或齿板信息；接着牙技师进行假牙的人工雕塑及上釉色，然后再将制作完成的假牙，再次以物流方式运送到牙医诊所；再这些过程中，物流往返将增加远距或跨国境运作的难度，牙模建模需要人工、牙模对色需要人工、假牙雕塑及上釉色，也都必须全部依赖专业技师人工，因此难以量产。
若以摄影机进行口腔牙齿取像，然后以显示屏幕呈像后进行牙模对色，会遇到摄影机取像环境光与显示屏幕，两者光谱不一致，造成严重的色差问题。此外、若要避免牙模或假牙的物流往返，可将牙模影像传送至牙技所，然后以显示屏幕呈像以取代实体牙模，接着牙技师依照显示屏幕上的牙齿信息，进行雕塑及上釉色，但此时，若假牙工作台的环境光与显示牙模的显示屏幕，两者的光谱不一致，也将再次造成严重的色差问题。
由于假牙的制作，除了假牙的立体形状会影响咬合功能外，假牙的颜色是否与口腔内其他健康牙齿兼容，更是必须考虑的美观因素，因此若要使用电子设备进行取像、以显示屏幕进行呈像、以照明光源辅助假牙工作平台进行假牙加工，如果设备间的色差问题没有被克服，将使假牙制作的各个阶段，都存在着严重的颜色失真因素，此乃造成假牙要达成跨远距、跨国境、信息化、自动化、及智能化生产最大的难题。

实现发明的最佳方式
如图1及图2所示，本实施例为一种无色差的影像扫描、显示及照明系统100，其包括：影像扫描仪10；显示屏幕20；以及照明光源30。
本发明可以应用于：在一端以影像扫描仪10进行样品取色及取样的取像，然后在取像现场以显示屏幕20进行呈像以核对颜色及形状，或者将样品影像送至远程的加工处所，以显示屏幕20呈像作为制作成品的样板，又工作台提供照明光源30，且以上从影像扫描仪10到显示屏幕20到照明光源30均为无色差的作业流程；也就是使影像扫描仪10、显示屏幕20、以及照明光源30间，以相同的光谱，避免样板与产品间的色差问题，以使所生产的产品与样品在颜色表现上，能够一致。
本发明特别可以应用于例如假牙制作流程、纺织品制作流程、鞋子制作流程等，用以消除取样设备、呈像屏幕、及制作环境光源间，因设备或环境差异性的色差，造成生产的产品颜色失真问题。
接下来，以假牙制作流程为实施例，其主要达成：1.消除设置在牙医诊所/医院200的影像扫描仪10及显示屏幕20间的色差问题；2.消除设置在牙技所300的显示屏幕20及照明光源30间的色差问题；3.消除设置在牙医诊所/医院及牙技所300间，所有的影像扫描仪10、显示屏幕20及照明光源30间的色差问题；借由将上述所有设备都具有相同的标准光谱，以克服假牙制作流程因设备色差，造成假牙颜色失真的问题。
如图3A至3C所示，因此本实施例的重要技术特征在于：影像扫描仪10、显示屏幕20及照明光源30，分别具有第一发光光谱41、第二发光光谱42及第三发光光谱43；又第一发光光谱41、第二发光光谱42及第三发光光谱43均为多个峰波长的波段组成的白光，且第一发光光谱41、第二发光光谱42、及第三发光光谱43均具有相同特征或相同特性曲线，因此可以使影像扫描仪10、显示屏幕20及照明光源30间，具有共同的标准光谱，以达成消除设备本身的色差问体。
上述第一发光光谱41、第二发光光谱42或第三发光光谱43的峰波长波段，可以均由相同的红色(R)、绿色(G、及蓝色(B)的分色，所组成的三色光谱。
又上述第一发光光谱41、第二发光光谱42或第三发光光谱43的峰波长波段，也可以均由相同的红色(R)、绿色(G)、蓝色(B)及黄色(Y)的分色，所组成的四色光谱。
又上述第一发光光谱41、第二发光光谱42或第三发光光谱43的峰波长波段，也可以均由相同的红色(R)、绿色(G)、蓝色(B)、青色(C)、洋红色(M)及黄色(Y)的分色，所组成的六色光谱。
如图4A及图4B所示，影像扫描仪10，其具有：光电取像成像系统110；多个第一光源120；及控制模块130。影像扫描仪10，其可以为可手持的装置，主要是在以假牙进行口腔治疗时，为了使制作后的假牙，与病患口腔内其他健康牙齿，在色彩的呈现上能够相符合，因此可以使用影像扫描仪10对病患口腔内的牙齿，进行影像扫描并完成2D或3D取样。
光电取像成像系统110，其主要包含了互补性氧化金属半导体 (CMOS)或电荷耦合元件(CCD)作为其光电转换元件。当光电取像成像系统110对口腔内牙齿进行光学取像后，借由上述光电转换元件将光信号转换成电信号，以便进行后续的传送及影像运算等；又光电取像成像系统110可包含成像光学系统，以进行影像成像。
如图5、图6A及图6B所示，第一光源120的设计，可以为环型第一光源121、平板型第一光源122或曲面型第一光源123。除此之外，第一光源120也可以设计成为屏蔽式光源124，其包括：屏蔽125；及可塑性元件126。
屏蔽125，有如一般氧气罩的型式，其为不透光且内部具有反光面125a的环状壁体，又屏蔽125的裙部具有罩口125b，以方便罩设及覆盖住病患的口腔外围。
可塑性元件126，可以是长条柱状体，可塑性元件126形成于屏蔽125的顶部且深入屏蔽125的内部，并具有结合穿孔126a，又该多个第一光源120形成于可塑性元件126的外表面，并且朝向屏蔽125内部的反光面125a投射第一发光光谱。
上述的结合穿孔126a，可以用以提供光电取像成像系统110插入，并且当该多个第一光源120的第一发光光谱投射在屏蔽125内部的反光面125a后，会再次反射并投射至病患的牙齿部位，如此可以使光电取像成像系统110，在第一发光光谱的照明下进行取像。
上述第一光源120的设计，其具有由多个峰波长的波段组成白光的第一发光光谱41，又第一光源120设置于光电取像成像系统110的外围，并以第一发光光谱41作为标准光谱，借此除了可以对光电取像成像系统110进行补光，使影像扫描仪10取得清晰的影像外，也能在标准光谱下建立标准取像影像。
如图7A及图7B所示，控制模块130，其主要控制使光电取像成像系统110，依时序分色撷取多个不同色的单色影像；也就是说，控制模块130依时序在不同的时间点，一次只撷取不同颜色的单一颜色的影像；例如对假牙可依时序撷取红色(R)、绿色(G)及蓝色(B)的单色影像；或者依时序撷取红色(R)、绿色(G)、蓝色(B)及黄色(Y)的单色影像；或者依时序撷取红色(R)、绿色(G)、蓝色(B)、青色(C)、洋红 色(M)及黄色(Y)的单色影像。
第一光源120是由多个像素单元(pixel)130所组成，又每一像素单元140又由多个分色像素单元(sub-pixel)150所组成，且每一个分色像素单元150是由固态光源151、荧光粉或量子点等波长转换材料152、然后再与上述三色分色、四色分色或六色分色的彩色滤波片153所形成，因而使第一光源120能发射产生三色光谱、四色光谱或六色光谱。
为了有效依时序进行单色取像，控制模块130可以依时序分色点亮该多个第一光源120的固态光源151，也就是每一时间只点亮一个分色彩色滤波片153对应的固态光源151，如此就可以使光电取像成像系统110，依时序分色撷取多个不同色的单色影像。
或者，可以在每一分色的彩色滤光片153与其对应的固态光源151间，进一步设有液晶控制单元154，此时，所有固态光源151被点亮，但控制模块130依时序分色控制液晶控制单元154的开启或关闭，就可以使光电取像成像系统110，能依时序分色撷取多个不同色的单色影像。
显示屏幕20，其主要用以将影像扫描仪10取得的牙齿影像再次呈现在显示屏幕20上，借由显示屏幕20的呈像，病患及牙医师就可以一起在假牙制作前，对假牙的颜色、辉度等先进行沟通及调整。
又为了使显示屏幕20呈像与影像扫描仪10取像间没有设备色差的问题，因此显示屏幕20的发光就非常重要，因此本实施例有关显示屏幕20的设计，是使显示屏幕20呈像时具有第二发光光谱42。
第二发光光谱42也是由多个峰波长的波段组成白光的第二发光光谱42，并且第二发光光谱42与第一发光光谱41具有相同特征，如此可以使显示屏幕20与影像扫描仪10间，在同一个标准光谱条件下，消除设备色差的问题。
照明光源30，当牙技师要制作假牙时，必须先掌握病患口腔内牙齿的影像作为模板，然后才能有所依据的进行假牙制造，又一般牙技师制造假牙的场所与牙医师的牙医诊所，并非在同一个地点。
在无法面对面或亲眼看到病患的请况下，此时牙技师可将牙医师处影像扫描仪10取得的影像，呈现在牙技所300的显示屏幕20上，作为其制作假牙的模板，而牙技所300的显示屏幕20与牙医师处的显示屏 幕20为相同的，同样具有相同的第二发光光谱42。
制作假牙时，通常需要一边临摹显示屏幕20呈像的牙齿影像模板，一边在假牙工作平台上制作假牙；若显示屏幕20与假牙工作平台的照明光源30，两者间存在设备色差，将会使牙技师误判颜色，如此假牙的颜色也会跟着失真。
因此假牙工作平台的照明光源30，在设计时使照明光源30具有第三发光光谱43，又第三发光光谱43也是由多个峰波长的波段组成白光的第三发光光谱43，并且第三发光光谱43与第二发光光谱42具有相同特征，如此可以使显示屏幕20与照明光源30间，在同一个标准光谱条件下，消除设备色差的问题。
惟上述各实施例是用以说明本发明的特点，其目的在使本技术领域的技术人员能了解本发明的内容并据以实施，而非限定本发明的保护范围，故凡其他未脱离本发明所揭示的精神而完成的等效修饰或修改，仍应包含在本发明权利要求所限定的范围内。
以上所述，仅是本发明的较佳实施例而已，并非对本发明做任何形式上的限制，虽然本发明已以较佳实施例揭露如上，然而并非用以限定本发明，任何熟悉本专业的技术人员，在不脱离本发明技术方案范围内，当可利用上述揭示的技术内容做出些许更动或修饰为等同变化的等效实施例，但凡是未脱离本发明技术方案的内容，依据本发明的技术实质对以上实施例所做的任何简单修改、等同变化与修饰，均仍属于本发明技术方案的范围内。
