Virtual human facial expression control method and device and computer program product

The invention provides a virtual human facial expression control method and device and a computer program product. The virtual human facial expression control method comprises the steps that a two-dimensional image of a user is collected, image processing is conducted on the two-dimensional image according to a first head model and a second head model of the user to obtain a target expression coefficient, the first head model is a head model established according to the head of the user, and the second head model is a head model established according to the head of the user; the second head model is a head model created according to the first head model; and controlling the facial expression of the first head model according to the target expression coefficient. 本发明提出了一种虚拟人面部表情的控制方法、装置和计算机程序产品。虚拟人面部表情的控制方法包括：采集用户的二维图像，根据用户的第一头部模型和第二头部模型，对二维图像进行图像处理，以得到目标表情系数，第一头部模型为根据用户的头部创建的头部模型，第二头部模型为根据第一头部模型创建的头部模型；根据目标表情系数，控制第一头部模型的面部表情。
