Face adjustment method and device of virtual image, computer equipment and storage medium

The invention provides a face adjustment method and device of a virtual image, computer equipment and a storage medium. The method comprises the following steps: identifying a mandibular contour of a to-be-adjusted image; determining a middle point and two end points of the mandibular contour; for any end point, determining a circle center corresponding to the to-be-adjusted half contour according to the positions of the end point and the middle point and the target radius; the to-be-adjusted half profile is a profile from the middle end point to the middle point of the lower jaw profile; according to the circle center and the target radius, adjusting the corresponding to-be-adjusted half contour to obtain a target half contour; and stretching the lower jaw of the to-be-adjusted image according to each target half profile. According to the method, the automatically generated virtual image can be quickly and efficiently beautified, the virtual image with an over-sharp lower jaw angle is changed into a shape mo
