区域覆盖的波前算法

发布于 2024-12-08 19:03:36 字数 184 浏览 1 评论 0原文

我想知道是否可以修改波前算法(或任何其他导航算法)到达特定目标位置以导航到所有可到达的位置。

关于不同类型的 WaveFront 算法的任何其他建议也会有所帮助。

I am wondering whether the Wavefront algorithm (or any other navigation algorithm), can be modified from trying to reach a a specific goal location to navigate to all reachable locations.

Any other advice on different types of WaveFront algorithm would also be helpful.

我访问过你的网站。你说机器人可以接收“去厨房”这样的命令。好吧,我建议不要重新发明轮子。实际上,您不必访问每个单元格或“洞区域”。相反,您应该选择到达它的最短路径,然后步行通过。

我相信 Dijkstra 算法 更适合您的机器人路径 -发现。

Dijkstra 的增强版本是 A* 算法,它采用平均情况下时间更少。

此处您可以找到它们如何高效工作的示例。

编辑:

我再次访问了您的网站。您说过您想要一种导航所有区域的算法。嗯,据我所知,重复A*算法会好很多。 A*使用BFS,在一般情况下有更好的性能。与波前相比,它非常有效。伪代码如下:

  • A) 使用A*算法找到位置和目标之间的最短路径
    • B) 如果无法到达目标,请指定一个临时位置并移动到该位置。 (既然你
      指出,稍后可能会找到方法)。到达临时位置后,转到步骤A。
    • C) 否则,如果您找到了方法,请导航至目标。

I have visited your site. You stated that the robot can receive commands like "Go to ketchen". Well, I advice not to re-invent the wheel. Actually, you don't have to visit every cell, or "the hole area". Rather, you should select your shortest path to it, then walk through.

I believe Dijkstra's algorithm is much better for your robot path-finding.

An enhaced version of Dijkstra is A* algorithm, which takes less time in the average case.

Here you can find examples how do they work, efficiently.

EDIT:

I have visited your site, again. You stated that you want an algorithm for navigating all the erea. Well, as far as I know, repeating A* algorithm will be much better. A* uses BFS, which has a better performance in the average case. It's very efficient when compared whith wavefront. The pseudocode is as following:

  • A) Find the shortest path with A* algorithm between the location and the goal
    • B) If there is no way to the goal, specify a temp location and move to it. (Since you
      indicated, it may find a way later). After arrived to temp location, Go to step A.
    • C) Otherwise, if you have found a way, navigate to the target.

这篇 1993 年的论文介绍了普通波前规划器的一种变体,除了从起点到目标的导航之外,它还实现了完全覆盖:

A. Zelinsky、RA Jarvis、JC Byrne、S. Yuta,“规划路径
移动机器人对非结构化环境的完全覆盖,”
国际先进机器人会议论文集,
1993 年,第 533-538 页。

另请参阅以下评论论文,了解有关覆盖路径规划的更多想法:

This 1993 paper introduced a variant of the vanilla wave-front planner that achieves complete coverage, in addition to navigation from start to goal:

complete coverage of an unstructured environment by a mobile robot,"

1993, pp. 533-538.
