Embodiment 1

[0029] like figure 1 As shown, a method for three-dimensional mapping of people's faces in a computer virtual world comprises the following steps:

[0030] Step 1. Provide a photo of the face, apply computer vision technology to identify the facial features of the photo, and obtain facial feature data; wherein, the photo of the face can be a photo taken or scanned, or it can be processed by graphics picture of. The face picture provided should preferably be a frontal, bareheaded, clean headshot, and the size and picture format meet the set requirements.

[0031] Step 2. Select the 3D face model texture that best matches the facial feature data from the prefabricated 3D face model textures, wherein the prefabricated 3D face model textures can be provided by virtual world game developers or service providers. pre-made;

[0032] Step 3: Synthesizing the photo of the face with the three-dimensional face model map. The synthesis method may be to generate a uniform texture with ...

Embodiment 2

[0048] like figure 2 As shown, a method for three-dimensional mapping of people's faces in a computer virtual world comprises the following steps:

[0049] Step 1. Provide a face photo, apply computer vision technology to carry out face feature recognition on the face photo, and obtain face feature data;

[0050] Step 2, generating a three-dimensional human face model map according to the facial feature data;

[0051] Step 3: Synthesizing the photo of the face with the three-dimensional face model map.

[0052] Wherein, the face feature recognition in the step 1 specifically includes the following steps:

[0053] 1) First identify the skin color, outline, eyes, mouth, and nose of the human face;

[0054] 2) Calculate eye size, interpupillary distance, distance from the center of the eyes to the tip of the nose, width and height of the mouth, distance from the center of the mouth to the tip of the nose, and distance from the center of the mouth to the chin.

[0055] 3) The...

Abstract

A three-dimensional mapping method of human faces in a computer virtual world comprises the following steps: Step 1, providing a human face photo, conducting human face feature recognition by using the computer vision technology, and acquiring human face feature data; Step 2, selecting the most matching three-dimensional human face model picture of the human face feature data in a prefabricated three-dimensional human face model picture, or generating a three-dimensional human face model picture according to the human feature data; and Step 3, combining the human face photo and the thee-dimensional human face model picture. A front three-dimensional virtual human face is rapidly and accurately generated according to the human face photo, and the human face picture is perfectly matched with the three-dimensional model. Even if a user who has no three-dimensional knowledge can create a three-dimensional role of the user himself in a short time. The method can be widely applicable to personal images or virtual characters in the virtual world, such as network interaction, web2.0, a virtual platform, communities, etc.

Description

technical field [0001] The invention relates to a method for three-dimensional mapping of human faces in a computer virtual world. Background technique [0002] Face is an important feature for people to recognize and communicate with each other, and it is also the main basis for people to recognize each other. The human face plays an extremely important role in the communication process between people, and is an important part of human beings expressing emotions to each other. In daily communication, by observing people's faces, we can infer people's personality and even guess their identity. In the computer virtual world, the virtual human face is the carrier of the expression of the virtual human. [0003] In recent years, with the rapid development of the network economy and the continuous maturity of the network interaction industry, the demand for the network interaction market has achieved sustained and rapid growth. The increase in the base of netizens has promote...
