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...

The invention relates to a facial expression tracking method for a VR head display. An expression database and a fingerprint database are pre-established. When a user uses it, the fingerprint is input through a fingerprint recognition module, and the fingerprint recognition module combines the fingerprint entered by the user with all the fingerprints in the fingerprint database. The information is matched; if the fingerprint identification module finds the same fingerprint information as the user in the fingerprint database, it immediately retrieves the user's facial expression package from the expression database, and the infrared camera module captures the user's facial expression in real time; the image processing module Compare the user's facial expression package with the facial expression captured by the infrared camera module in real time, and when the image processing module detects that the user's facial expression is consistent with a certain expression in the facial expression package, the expression will be transmitted immediately And reflect it through virtual characters. The expression tracking method of the present invention can quickly and stably track the user's facial expression, and realistically and accurately synthesize the expression of the virtual character.
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...
