Research On Computer Aided Eyeglasses Virtual Try On Technique And It's Application

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.
