摘　　要：火灾逃生教育具有重要的现实意义,但在现实生活中,面向公众的火灾逃生演练通常花费很大。虚拟现实技术也能模拟火灾场景,可以增强逃生教育的效果,同时能大大降低训练的费用。建立了面向火灾逃生训练的虚拟现实原型系统,我们编制了集粒子动画和声音于一体的游戏风格图形界面,用户可以控制替身在虚拟火灾场景中逃生,替身的运动采用骨骼动画实现,我们使用面部表情图片来描述替身的情绪状态。初步的实验结果表明,该演示系统能够使火灾逃生演练变得更形象。Fire escape education has very important practical significance, and a fire escape training for public is usually expensive in real life. Virtual reality can simulate a fire scene and enhance escape education. Meanwhile it can reduce the overall training costs greatly. A virtual reality demo system for fire escape training was set up, a game-like graphics interface with particle animation and sounds was programmed, a user could control an avatar to escape from the virtual fire scene, the avatar’s movement was realized in skeleton animation, and a facial expression picture was used to express the avatar’s emotion state. The preliminary test shows that the demo system can make fire escape training to be more vivid.
