Step S110, collecting user head images of different orientations.

The user image is captured by a camera or other mobile electronic device that includes not only the user's head image but also the background in which the user is located, from which the user's head image is captured. In other words, the background image in the user image is cleared, and the image of the user's head is retained. It is easy to understand that it is necessary to collect image of the user's head in different directions to obtain more image data for subsequent data processing.

Step S120: Establish a human head model according to the collected image of the user's head.

The head model is built using modeling software stored on the service terminal 100 based on the acquired plurality of user head images of different orientations.

Step S130, adjusting the selected preset glasses model parameters.

The service terminal 100 pre-stores a plurality of glasses models, and when the user performs the virtual glasses trial, the user can select one of the pair of glasses models according to his or her preference. The service terminal 100 adjusts parameters of the glasses model selected by the user such that the selected glasses model of the user can be adapted to the human head model established according to the image of the user's head. The parameters of the glasses model include, but are not limited to, the outer width of the eyeglass frame, the width of the frame surface, the frame size, the height of the frame, the height of the bridge of the nose, and the length of the corner of the temple from the bend of the eyeglass.

The eyeglass model after adjusting the parameters is matched with the human head model so that the user can actually feel the wearing effect of the glasses. Specifically, the eyeglass model is placed at a suitable position of the human head model to fit the nose pad to the nose bridge of the human head model, and the center point of the frame and the central axis of the human head model are aligned to achieve the eyeglass model and the human head model. Accurate fit. Easy to understand, users can also choose a variety of different glasses models to try on according to their own preferences.

Step S210, collecting user head images of different orientations.

Step S220, establishing a head model according to the collected image of the user's head.

Step S230, adjusting parameters of the selected preset glasses model.

A plurality of glasses models are pre-stored in the service terminal 100, and when the user performs the virtual glasses trial, one of the pair of glasses models can be selected according to his or her preference. The service terminal 100 adjusts parameters of the glasses model selected by the user such that the selected glasses model of the user can be adapted to the human head model established according to the image of the user's head. The parameters of the glasses model include, but are not limited to, the outer width of the eyeglass frame, the width of the frame surface, the frame size, the height of the frame, the height of the bridge of the nose, and the length of the corner of the temple from the bend of the eyeglass.

Referring to FIG. 4, it is a flowchart of sub-steps of step S240 of another virtual glasses fitting method according to an embodiment of the present invention.

In step S241, the simulated application scene performs light rendering on the preset glasses model, so that the preset glasses model conforms to the application scenario in which the user is located.

According to the environment in which the user is located, the indoor environment or the outdoor environment is selected separately, and then the glasses model is rendered. Specifically, the light is divided into a main light source and an auxiliary light source, and the main light source is respectively disposed in front of the glasses model and on the left and right sides, and the auxiliary light source is distributed around the glasses model, according to the actual environment of the user, that is, the indoor environment or the outdoor environment. Adjust the intensity of the primary and secondary sources to achieve the effect of light rendering. In turn, the user's application environment is simulated, the user's adaptability is enhanced, and the user's experience is improved.

Step S242, performing color setting on the preset glasses model, so that the preset glasses model exhibits a stereoscopic effect.

The glasses model selected by the user is colored, such as red, to make the glasses model more beautiful, and at the same time increase the stereoscopic effect of the glasses model to improve the user experience.

Step S250: Perform motion synchronization processing on the preset glasses model and the shadow of the preset glasses model to control the shadow motion of the preset glasses model and the preset glasses model.

The eyeglass model selected by the user and the shadow formed by the eyeglass model are subjected to motion synchronization processing. Specifically, the eyeglass model and the shadow corresponding to the eyeglass model are equally divided into three parts, and each part is subjected to motion synchronization processing.

Algorithm for synchronizing the first part of the eyeglass model and the corresponding shadow of the eyeglass model

Adjustment is made, where (u, v) represents the coordinates before the shadow motion, and (u', v') represents the coordinates after the shadow motion. Set is the influence factor of the movement of the glasses model on the shadow motion of the glasses model, and represents the amount of movement of the eyeglass model in the coordinate system to the amount of movement of the shadow of the glasses model in the coordinate system. Further, the motion of the glasses model is correlated with the motion of the shadow of the glasses model to realize the shadow synchronous motion of the glasses model and the glasses model. The set of influence factors is obtained by the algorithm vSet=w*s*V, where w and s are constant values, generally, w=0.04, s=0.4.

The second part of the glasses model and the synchronized motion of the shadow corresponding to the glasses model are calculated

The law {v'=(v+y)Set y=vSet-[|uu _O |-|u _A -U _O |]*tan n,

The adjustment is made, where u _O , u _A , u _B , u _C are the abscissas of point O, point A, point B, and point C on the randomly selected glasses model. The algorithm makes the second part of the glasses model and the corresponding shadow of the glasses model move synchronously.

A new glasses model is generated to enrich the style of the glasses model stored within the service terminal 100.

Step S340, selecting different materials and textures for each of the plurality of preset glasses models.

The glasses model established by the service terminal 100 using the modeling software is only a simple glasses model, so the glasses model needs to be modified to make the glasses model have an aesthetic effect to improve the user experience. Specifically, a suitable material and texture are selected for each of the glasses models, and the material may be, but not limited to, plastic or metal, and the texture may be, but not limited to, corrugations or straight lines. By selecting the appropriate material and texture for each eyeglass model, each eyeglass model is more aesthetically pleasing.

The service terminal 100 adjusts the parameters of the glasses model selected by the user such that the selected glasses model of the user can be adapted to the human head model established from the image of the user's head. The parameters of the glasses model include, but are not limited to, the outer width of the eyeglass frame, the width of the frame surface, the frame size, the height of the frame, the height of the bridge of the nose, and the length of the corner of the temple from the bend of the eyeglass.

Adjustment is made, where (u, v) represents the coordinates before the shadow motion, and (u', v') represents the coordinates after the shadow motion. Set is the influence factor of the movement of the glasses model on the shadow motion of the glasses model, and represents the amount of movement of the eyeglass model in the coordinate system to the amount of movement of the shadow of the glasses model in the coordinate system. Further correlating the motion of the eyeglass model with the motion of the shadow of the eyeglass model,
