Problems solved by technology

The disadvantages of this method are: the lack of realism and texture features of continuous changes in facial muscles; marking on the human face will cause discomfort, and the dependence on marking limits the scope of obtaining geometric information from the marking position; and This method belongs to the method of mathematical modeling, and the obtained 3D data is not the real 3D data of the face.
The disadvantage of this method is that special equipment is required, and no matter it is structured light scanning or l

Embodiment Construction

[0057] The present invention will be further described below in conjunction with accompanying drawing:

[0058] Such as figure 1 As shown, the method for reconstructing face real-time three-dimensional data by multiple images described in the present invention comprises the following steps:

[0059] (1) Build a camera system: such as figure 1 As shown, eight cameras numbered 1, 2, 3, 4, 5, 6, 7, and 8 are distributed around the face, among which, cameras 1 and 2 are used to capture the left face; It is used to shoot the transition part between the left face and the front face; cameras 4 and 5 are used to shoot the front face; camera 6 is used to shoot the transition part between the front face and the right face; cameras 7 and 8 are used to shoot The face on the right side; the signal output terminals of the eight cameras are correspondingly connected to the signal input terminals of the processor, and the processor is used for data processing of the acquired images;

Abstract

The invention discloses a method for reconstructing real-time three-dimensional face data with multiple images. The method includes the following steps: constructing shooting systems of eight cameras; performing multi-camera calibration; performing image matching, to be more specific, calculating global matching points of an ith group of images, and calculating accurate matching points of the ith group of images; calculating three-dimensional face coordinates via the matching points and a projection matrix of the cameras, to be more specific, imaging an object point on the third image of the ith group, and taking an intersection of three projection lines as the object point so as to complete reconstructing of the real-time three-dimensional face data. The face data obtained in the method are global, dense and real-time and can be used directly, and the method can be widely applied to the fields such as the animation industry, computer 3D (three-dimensional) games, human-computer interaction, identity recognition, medical virtual surgery, videophones, face recognition, face expression, age simulation, film and TV advertising production and computer cognition.

Description

technical field [0001] The invention relates to a method for three-dimensional reconstruction of human face, in particular to a method for reconstructing real-time three-dimensional data of human face from multiple images. Background technique [0002] The existing three-dimensional face reconstruction methods mainly include elastic mesh deformation method and structured light scanning method. The technical solutions and defects of these two traditional methods are: [0003] (1) Elastic mesh deformation method: use the information extracted from the continuous video image sequence as the control input of the animation system, track the various feature points of the performer's face and map the texture to the polygonal model; the specific method is to use the reflective ball Paste on the face to track the movement of the face, and obtain the three-dimensional data of the face through mathematical modeling from several key points of the face. The disadvantages of this method ...
