ERT-VR:一种地震救援训练虚拟仿真系统
|
摘要
ERT-VR系统主要包括指挥员训练子系统与小组训练子系统两部分。指挥员训练子系统基于多通道立体显示系统构建沉浸环境,小组训练子系统以头盔显示器与数据手套等为主要交互设备。ERT-VR设计与实现了一个训练想定生成器,生成的想定数据类似于试题,管理人员分配给受训人员。受训过程被实时记录与评估。阐述了ERT-VR系统组成、功能结构、运行过程与运行实例。
ERT-VR is composed of the commander training subsystem and the team training subsystem. In the commander training subsystem, the display system based on stereoscopic projectors is used to train the emergency rescue commanders. In the team training subsystem, the members of the operational teams use the head-mounted displays and datagloves as the interactive devices. A 3D scenario creator was designed and implemented in ERT-VR. Instructors assigned a specific training scenario to the trainees by using the scenario creator. Trainees took on the role of the characters in the training scenario and controlled their actions and ultimately the scenario outcomes. All the actions were recorded into the database system and could be replayed and evaluated. The components, architecture, run process and run samples of ERT-VR were proposed.
