Abstract: The behavior control of virtual character is an important part of the virtual fire escape system. In the process of fire escape, the health condition of the evacuees is not only the only criterion to evaluate the success of escape, but also one of the important factors that affect the escape behavior. In this paper, the health degree is introduced, the environment factors affecting the health of body are analyzed, such as thermal radiation, temperature, toxic gas and lean oxygen status, and the effects of health degree on escape behavior are analyzed. The behavior control model of virtual fire escape based on health degree is set up. The test shows that this model can simulate fire escape effectively, and improve the reality of virtual fire escape training effectively.

Key words: virtual reality, fire escape, behavior control, health degree

摘要: 虚拟角色的行为控制是虚拟火灾逃生系统的重要组成部分。在逃生过程中,火灾环境中的各种危害因素会对逃生人员的身体健康产生严重影响,而健康状况又会对逃生人员的逃生行为和速度产生重要影响。为了使虚拟角色的行为控制更加符合这一实际情况,引入了健康度的概念,分析了火灾环境中热辐射、温度、有毒烟气、“贫氧”状况等主要因素对健康状况的影响,以及健康状况对逃生行为的影响,建立了基于健康度的虚拟火灾逃生行为控制模型。实验结果表明,该模型能较真实地模拟火灾逃生行为,有效地提高了虚拟火灾逃生训练的真实感。
