Abstract

The invention provides a method and device for carrying out a video call based on virtual face expressions. The method comprises the steps of acquiring first video frame data and first audio data corresponding to the first video frame data sent by a first user based on a call terminal continuously in real time, wherein the first video frame data comprises first face feature values of the first user; selecting a virtual face model and generating the virtual face expressions corresponding to the virtual face model according to the first video frame data; and playing the virtual face expressionscontinuously in real time, and decoding and playing the corresponding first audio data at the same time. According to the method, the other party in the video call only needs to provide data comprising the face feature values, then a local terminal regenerates the virtual face expressions only comprising the expression information of the user at the opposite side according to the face feature values and the virtual face model, the information of the user at the opposite side can be prevented from being leaked, the information security is ensured, and the privacy can be improved.

Description

technical field [0001] The invention relates to the technical field of video calls, in particular to a method and device for video calls based on virtual facial expressions. Background technique [0002] At present, when a user makes a video call, he generally chooses a computer, a mobile phone, or other electronic equipment with a camera, and transmits video signals collected by the above-mentioned electronic equipment through the Internet, thereby realizing a video call. Specifically, both parties in the video call use the front camera of the electronic device to capture information about faces or objects, and obtain sound information through the earpiece of the electronic device, thereby realizing the video call. [0003] In the process of realizing the invention, the inventor found that the existing solutions have at least the following defects: [0004] The existing video call method will use the original video image and the user's original voice, which has poor privac...
