Expression image data processing method and device and server

The invention provides an expression image data processing method, an expression image data processing device and a server, which can be applied to the technical field of artificial intelligence. Based on the method, after a target image containing a face image of a target object is obtained, geometric features and angle features can be obtained through extraction according to a plurality of expression key points determined and obtained based on the target image; meanwhile, based on the target image, determining and extracting a texture feature according to an expression key area; and determining the facial expression of the target object in the target image by simultaneously processing the geometric features, the angle features and the texture features by using a preset expression recognition model. The facial expression of the target object in the target image is efficiently and accurately identified and determined by extracting, combining and using the geometric features, the angle features, the texture fe
