摘    要:针对当前井巷漫游方式在灵活性和易用性方面的不足,提出一种将全路径网络作为漫游相机运动轨道的交互式漫游方式。全路径网络由原始结点、虚拟结点、原始边和虚拟边组成,具有2个特征:交岔口处存在全路径和结点边表的有序性。运用有限状态机的原理对漫游器的交互式行为进行建模,从地下矿可视化生产管控系统对漫游器的功能需求出发,采用面向对象的思想和State模式设计漫游器相关对象的类结构,并在可视化生产管控平台上实现一个漫游器实例。研究结果表明:此漫游方式可供用户交互式地在网状的地下巷道内快速巡视,且拐弯处画面流畅,在功能的灵活性和操作的易用性方面取得较好的平衡,增强井巷漫游功能的可操作性。

Abstract: Aimed at the challenges that the traditional roadway roaming mode confronted in improving flexibility and easy use, a interactive roadway roaming mode based on the virtual full path roaming network (VFPRN) was proposed. VFPRN is composed of node, edge, virtual node and virtual edge. It has two outstanding characteristics, one is the full path at the intersection, another is the orderliness of edges. The behaviors of roaming module were modeled based on the finite state machine theory. According to the functional requirement of roadway roaming in the underground mine 3D visual production management and control system (UMPMCS), the correlative classes were designed by adopting the object-oriented idea and state pattern, and implemented based on UMPMCS. The results show that users can roam quickly in the underground roadway network by this roaming mode, and the frames are displayed smoothly at the intersection. This roaming mode realizes the balance of flexibility and easy use, and improves the operability of roaming function.
