    随着人们物质生活水平的提高，消费者对眼镜商品的要求也在不断提高。人们对它的要求已经不仅局限于能看清楚物体，而更加重视眼镜的品牌、材料、款式、颜色，希望能从琳琅满目的商品中选出最适合本人气质与个性的眼镜。传统的眼镜零售店在面对新生代消费群体时，无法以快捷、方便的服务来满足他们；而另一部分眼疾患者，在眼镜店挑选镜架时难以看清试戴效果，染色镜片也不能预先看到试戴效果……这些因素造成顾客对最终配镜的满意度降低。
    虚拟试戴技术是眼镜行业信息化建设中的关键技术。本文在充分研究眼镜学相关背景知识上，设计出了眼镜框架拍摄平台；结合镜架本身特点，设计出一种基于sobel算子轮廓提取加目标区域描绘的图像分割方法；运用图像几何变换技术实现了人脸与镜架按照真实比例的试戴；结合种子填充算法与透明度混色算法，实现了各种颜色，均匀与渐变染色镜片的染色效果；选用Visual C#编程工具，和Microsoft SQL Server 2000 数据库系统，设计出了一套C/S模式的选镜系统。
    选镜系统的应用要以技术为前提，科学为导向，正确引导消费者去从中受益。经验丰富的验光师、先进的选镜系统、认真负责的定配师、性能优异的设备等客观条件，加上眼疾患者主观的默契配合，才能制作出一付既美观，又舒适的眼镜。所以选镜系统定位为在眼镜零售实体店内，作为顾客选镜参考的销售工具。顾客在眼镜店挑选眼镜，可以像在图书馆的电脑上选书一样，设置好搜索条件，符合搜索条件镜架就能一一试戴，并能进行染色镜片的效果演示，从而选择出最喜欢的眼镜。
    本文实现了人脸与镜架按照真实比例的试戴，并且实现了多种颜色均匀与渐变染色镜片的染色效果演示。同时通过结合数据库技术，消费者可以设置搜索条件，快捷的搜索到自己喜欢的眼镜。实验证明，对于各种种类的镜框、各种类型染色镜片，虚拟试戴均能取得较好的效果。

    Along with the raise of the Level of people’s material life, consumer’s requests of the quality of eyeglasses are also improved. Their requests are not limited to see object clearly, but pay more attention to the eyeglasses’s brand, material, design, color, and hope to select the eyeglasses which is best suitable for his or her temperament and individuality from arrays of beautiful exhibits. Traditional retail trade of eyeglasses can’t supply rapid and convenient service when they meet the Cainozonic; on the other hand , people whose eyesight is not good can’t see their face clearly when they select eyeglasses frames; lens dyed different color can’t be tried on……,all this lead to the reduction of consumer’s satisfaction.
    Virtual try on technology is the most critical technology in eyeglasses information construction. Based on deeply researching background knowledge of eyeglasses, in this pager ,we designed the platform of taking the picture of eyeglasses frame; considering the characters of the eyeglasses frame, we designed an image segmentation method based on sobel operator edge-detection and painting the target object; realized the true proportion virtual try on using the digital image geometric operation; using the flood-fill algorithm and transparency algorithm, we realized the effect of lens in uniform and non-uniform different color；using Visual C# , and the Microsoft SQL Server 2000 Database, we developed a eyeglasses selecting system with C/S mode.
    The application of eyeglasses selecting system must take the technology as the precondition , and use it according to science, let the customers benefit from it correctly. Experimental optometrist、advanced eyeglasses selecting system、serious maker、excellent equipment and the tacit cooperation with the patient, all those condition leads to a beautiful and comfortable eyeglasses. So the eyeglasses selecting system orientated to the eyeglasses retail store as the tool of the sale used by customers. Customers in eyeglasses store can select eyeglasses just as search books in library using computer, when the conditions are set, the eyeglasses frame which according the conditions were displayed. they and be tried on one by one, and then dying the lens ,consequently select the most favorable one. 
    In the paper, we realized the true proportion virtual try on and realized the effect of lens in uniform and non-uniform different color. Using the technology of database, consumers could search their favorites quickly through select some items. Experiment has proved that the effect of virtual try on is good, no matter what’s kinds of frames and color of lens.
