摘　　要：在武警执勤训练中,沙盘训练方式存在着真实感较差、模型不可变等缺陷,影响训练效果。而采用虚拟现实技术,构建虚拟战场仿真系统,是克服这一缺陷的可行方法。基于VRML与Web Services技术,研究并实现了一个应用于武警执勤训练的三维在线虚拟战场仿真系统。给出了系统架构,并对其核心功能实现作了详细说明,最后给出了该系统的一个场景仿真实例及其性能分析。结果表明:三维在线虚拟战场仿真系统应用于武警执勤模拟训练,取得较好效果。In the training of armed police＇s duty,a sand-table training method has some defects,such as less immersion,worse variability,which leads to an unsatisfactory training effect.Using virtual reality technology to construct a virtual battlefield simulation system is a feasible way to overcome these shortcomings.A three-dimensional simulation system of a virtual battlefield was studied and developed based on VRML and Web Services for the training of armed police.First,the software architecture of this system was proposed.Then the core functions of the system were discussed in detail.Finally,a simulative instance of training scene was given and its performance was analyzed.The result shows this system is useful in improving training effect according to the feedback from the armed police.
