Embodiment

[0023] Embodiment: A facial expression tracking method for a VR head display

[0024] Build an expression tracking platform in advance, the expression tracking platform includes VR head display, infrared camera module, fingerprint identification module, image processing module, the image processing module is connected with VR head display, fingerprint identification module and infrared camera module respectively, and according to The following steps perform facial expression tracking.

[0025] See attached figure 1 , the first step is to establish an expression database in advance, which is used to store the user information of the user and various facial expression packages of the user; pre-suggest a fingerprint database, which is used to store the user information of the user and the fingerprint information of the user ;

[0026] In the second step, users are respectively established in the expression database and the fingerprint database, and the fingerprint information o...

Abstract

The invention relates to a facial expression tracking method of a VR head-mounted display. The method includes: an expression database and a fingerprint database are pre-established, during usage by a user, fingerprint input is performed through a fingerprint identification module, and then the fingerprint identification module pairs fingerprints input by the user and all fingerprint information in the fingerprint database; if the fingerprint identification module searches fingerprint information same with the user in the fingerprint database, a facial expression packaging of the user is immediately called from the expression database, and an infrared shooting module captures a facial expression of the user in real time; and an image processing module compares the facial expression package of the user with the face expression captured by the infrared shooting module in real time, and when the image processing module searches that the facial expression of the user and a certain expression in the facial expression package are consistent, the expression is immediately transmitted and reflected through a virtual role. According to the expression tracking method, facial expressions of the users can be rapidly and stably tracked, and expressions of the virtual roles can be vividly and accurately synthesized.

Description

technical field [0001] The invention belongs to the technical field of virtual reality (VR for short), and in particular relates to a facial expression tracking method for a VR head-mounted display. Background technique [0002] With the rapid development of VR technology, there are more and more VR devices on the market, such as VR headsets, VR glasses, glasses VR, etc., using simulation technology and computer graphics man-machine interface technology multimedia technology sensing technology The product of a collection of various technologies such as network technology is a brand-new means of human-computer interaction created with the help of computers and the latest sensor technology. VR equipment uses computing simulation to generate a three-dimensional virtual world, providing users with simulations of vision, hearing, touch and other senses, making users feel as if they are actually there, thus bringing users a brand-new viewing experience. Virtual character animatio...
