Abstract

The invention relates to an interactive generation method for a realistic virtual incarnate model based on a component library, comprising the steps: firstly, according to gender parameters, body height parameters, age parameters, hairstyle parameters, clothing parameters and equipment parameters appointed by a user, a corresponding skeleton model and a corresponding outer layer skin model are respectively generated based on the component library, and a virtual incarnate model with the realistic characteristic is established in a superposition way; secondly, characteristic points of left eye, right eye, nose, mouth, chin, left ear and right ear on a human face photo are selected in an interaction way, the photo is mapped onto a face grid of the incarnate model by adopting a texture mapping technology, thereby the virtual incarnate model with the reality is generated. On the basis of the prior technical scheme, the invention can save a great deal of time and resources by fully utilizing the prior component library data, can increase the reality of the incarnate model without changing geometric data of the model by customizing face textures of the incarnate model in the interaction way, and increases the immersive characteristic to develop common activities among multiple users in a subsequent virtual environment.

Description

technical field [0001] The invention relates to an interactive generation method of a realistic virtual avatar model based on a component library, and belongs to the technical field of virtual reality (Virtual Reality, VR) and online games. Background technique [0002] Virtual environment is a comprehensive technology involving computer graphics, image processing, human-computer interaction, artificial intelligence and other disciplines. To increase realism, many virtual environments add virtual avatars (Avatars) representing users through which they interact with the environment and other users in the environment. The virtual avatar determines the information and feelings that the end user directly receives, and allows the user to map his face picture to the face grid of his avatar model, which can further reflect the reality of the avatar model in the virtual environment. At present, the representation methods of the avatar model include stick model, volume model, surfac...
