智能化虚拟人感知模型的一种探索性研究

在智能化虚拟人自主行为模型的研究过程中，感知功能是建立虚拟人行为模型的基础．如何能够构建出准确模拟人类感知功能的感知模型是其研究的难点．本文在介绍三维虚拟场詈的建立和虚拟人模型的创建的基础上，着重讨论了虚拟人感知模型的一种实现方法．该方法通过建立空间查询表，对创建的虚拟场景信息进行有效地管理与查询，虚拟人实时对空间查询表进行查询，并引入基于AABB包围盒的碰撞检测算法对是否存在障碍物进行判断，引导自身进行下一步的动作，初步实现了对环境信息的感知．

An exploring research of intelligent virtual human''''s perception model

The perceptive function is the foundation of virtual human behavior modeling in the research of the intelligent virtual human autonomous behavior model.How to exactly construct human's perceptive function is a challenge.This paper presents how to set up a 3D virtual scene and virtual human models,on the basis of which emphasizes a realized method of virtual human's perception model.In the method,we construct a spatial inquiry table to manage and inquire the information of the scene.Virtual human can access information through the table anytime and the collision detection algorithm,in the light of which to judge whether there is any barriers,and to take decision to the next action. It is primarily realized the perception to the virtual environment.
