Research On Virtual Glasses Try-on Technology Based On Augmented Reality

In recent years,e-commerce has been booming,and virtual try-on technology has emerged.this paper combines virtual glasses into video streams and uses augmented reality technology to achieve the effect of virtual glasses try-on.So that users can human-computer interaction in real time,and the user's shopping experience improves.The main research of this paper is as follows:In the face detection phase,The method of face detection used in this paper is the combination of AdaBoost cascade classifier and SVM classifier based Hog feature,The method reduces the false detection rate while reducing the miss detection rate,so that the accuracy of face detection is improved.In the face alignment phase,the robustness of the SIFT algorithm is used to do the local feature extraction,and the SDM algorithm is used to refine the feature point alignment iterative refinement,and the more accurate feature point alignment model is trained.The accuracy of face alignment is higher than the method of traditional ASM.In this paper,virtual glasses processing based on pose estimation is proposed,and from two stages to introduce.First do the head pose estimate.because of the attitude estimation method based on geometric projection,the L-M optimization algorithm is used to solve the nonlinear least squares method in the process of attitude estimation.The fit is better and the attitude estimation is more accurate.In the stage of virtual glasses processing.In this paper,the glasses image do appropriate perspective transformation used the rotation angle of attitude estimation,so that it presents a three-dimensional effect,and avoid the situation of exaggerated deformation.The combination of glasses legs and glasses,in the head rotation,according to the rotation angle to calculate and display the length of the glasses legs,display the three-dimensional effect of glasses try-on to user.Finally,this paper will be virtual glasses trying technology applied to the virtual eyeglass try-on system,designed to complete a simple virtual eyeglass try-on system.Experiments show that the virtual glasses try-on technology in this paper can meet the requirements of users,and can show a satisfactory eyeglass try-on effect.
