Embodiment Construction

[0013] A method for quickly inserting players in electronic games, the process of game player face modeling is as follows: figure 1 As shown, the specific steps are as follows:

[0014] S1.1, face detection and key point positioning: perform face detection on the game player images captured by ordinary cameras, first determine the approximate position of the face, and then use the key point positioning technology to find the feature points on the front face, These feature points are divided into five groups of mouth, eyes, nose, eyebrows, and contour. The two-dimensional information (x, y value) of the feature points is obtained, and the texture map of the frontal face is obtained, and the average color of the face is calculated. The color of the region is averaged, and the ear and tooth textures are combined to form a texture map;

[0015] S1.2, Depth Information Estimation: Preprocess 100 Chinese face models built with a 3D scanner to obtain 3D data of corresponding feature...

Abstract

The invention is a fast player posting method in an electronic game, relates to the field of 3D image processing technique, comprising: making detection and key point location on the right face of a player detected by a camera so as to be able to accurately obtain human face characteristic information; according to 3D human face database, building a corresponding relation between right and side face parameters, estimating the depth information of face characteristic points of the player; using the detection results, obtaining a face outline texture diagram to form a face texture diagram; using the radius basic function interpolation to deform standard model and making texture fitting, and obtaining a real face model of the player, thus strengthening the immersing sense of the player.

Description

technical field [0001] The invention relates to the technical field of three-dimensional image processing, in particular to electronic games, pattern recognition and computer graphics, and a method for quickly placing players in electronic games based on automatic generation of game characters and rapid modeling of personalized three-dimensional faces. Background technique [0002] An important development trend of the current game is to have a sense of authenticity and immersion. If the game character is changed into the image of the player, the immersion of the game player can be increased and the interest of the game player can be increased. This involves face modeling technology. As a research branch of computer graphics, face modeling has made great progress through the efforts of scientific workers in the past 30 years. With the continuous increase of application requirements in the fields of human-computer interface, interactive games, multimedia, and virtual reality...
