| 摘 要： | 为了以最小代价快速抓捕逃逸的目标车辆,利用凸包和图论的方法研究了目标车辆的动态围堵问题。对传统凸包算法进行改进,基于快速凸包算法形成了节点数最少的完全包围圈;将警力调度问题转化为加权二分图匹配问题,并求出耗时最少的警力调度结果,最后形成具体的围堵方案。改进后的快速凸包算法结合警力调度算法能在相对较短时间内对逃逸车辆完成围堵。

| Abstract: | In order to catch the escaping vehicle quickly with minimum cost, the dynamic containment problem of the target vehicle is studied by using convex hull and graph theory. The police scheduling problem is transformed into a weighted bipartite graph matching problem, and the result of police scheduling with the least time is obtained. Finally, a specific containment scheme is formed, and the improved fast convex hull algorithm combined with the police scheduling algorithm can complete the containment of the escaping vehicles in a relatively short time |
