Expression driving method and device, electronic equipment and storage medium

The invention discloses an expression driving method and a device, electronic equipment and a storage medium, and relates to the field of artificial intelligence, and the method can comprise the steps: carrying out the face key point detection of a driven person in a first image, and obtaining a first face key point sequence; for each second image obtained in sequence, the following processing iscarried out: performing face key point detection on a driving person in each second image to obtain a second face key point sequence; analyzing the second face key point sequence if the no-expressionframe image is not determined currently, and taking the second face key point sequence as a no-expression key point sequence if the second image is determined to be the no-expression frame image basedon an analysis result; and otherwise, obtaining a deviation value between the second face key point sequence and the expression-free key point sequence, and performing expression driving rendering onthe driven person based on
