Generation method and generation system of hair style effect pictures

Abstract

The utility model discloses a generation method and a generation system of hair style effect pictures. The generation method and the generation system of the hair style effect pictures comprise the following steps of acquiring key point (such as double-eye, a lip, a nose and a face outline) information of a first face picture of a collected user, modifying a face three dimensional (3D) module master plate according to the key point information, acquiring a 3D module of the user and the key point information of hair style pictures needed by the user, ensuring deflection angles of the hair style pictures, conducting corresponding angle deflection of the 3D module of the user, acquiring a second face picture of the user according to the 3D module after being deflected, combining the second face picture and the hair style pictures and generating the hair style effect pictures. Because the technical means of 3D restore of the first face picture of the user is adopted and the 3D module of the user is rotated, face pictures with different angles are acquired, and the problem that the same face picture can not be matched with the hair style pictures with all kinds of deflection angles is solved.

Description

technical field [0001] The present invention relates to the technical field of hairstyle design, and more specifically, to a method and system for generating a hairstyle effect diagram. Background technique [0002] Hairstyling is a technical means of virtually changing hairstyles on facial images through the hairstyling system. [0003] A hairstyle design method in the prior art is to simply combine hairstyle images and face pictures. Although this method can also generate hairstyle renderings, the controllability of the hair on the face position is low, and continuous manual adjustment is required, which increases the complexity of the user's use. Therefore, this hair styling method is not really applied to the market or widely used by netizens, but only as an online entertainment. Another hairstyle design method is a method based on face positioning and face shape calculation to match hairstyles. This method applies technologies such as face detection, and can automatic...

[0004] However, the second hairstyle design method does not consider how the same face image matches hairstyle images from various angles. For example, if the experiencer is a frontal image, the hairstyle image to be changed is a side face hairstyle image.

Therefore, the second hairstyle design method has certain limitations for the generation of hairstyle renderings.
