Face expression detection method, apparatus, device, system and medium

Abstract

The invention discloses a facial expression detection method, an apparatus, a device, a system and a computer-readable storage medium. The method comprises the following steps: receiving a video picture of each frame transmitted by a head-mounted camera; performing face detection on the video picture according to a preset face detection model; When a human face is detected in the video picture, the coordinates of the key points of the human face are obtained according to a key point detection model established in advance; Detecting facial expression according to the key point coordinates and the static key point coordinates corresponding to the face stored in advance; The invention simply and efficiently realizes the facial expression detection process, improves the operation efficiency and realizes the comprehensive utilization of the operation resources.

Description

Technical field

[0001] The present invention relates to the field of computer technology, in particular to a method, device, equipment, system and computer-readable storage medium for detecting facial expressions. Background technique

[0002] In recent years, with the development of computer graphics, computer animation technology to synthesize human facial expression animation is one of the focuses of current animation research. It enables animators to directly drive the image model with the actor’s expression, which is influenced by animation. Producers pay more attention. Facial expression capture can detect and record the performer’s expression in real time, and convert it into a digital "abstract expression" so that the animation software can "gave" it to the model so that the model has the same expression as the performer and generates the final expression animation sequence .

[0003] The existing more mature expression capture and detection technology is the marker-point...
