InProceedings of the AAAI Conference on Artificial Intelligence (AAAI),2010. Abstract: Grids with blocked and unblocked cells are often used to represent continuous 2D and 3D environments in robotics and video games. The shortest paths formed 在本文一开始我们就提到了路径规划的两个核心问题,其中第一个便是抽象图数据问题。理论上讲,能够与多种抽象图数据结构兼容的路线生成算法,其应用的广泛性也会更高。在这一点上,Theta * 并不依赖特定的抽象图数据,它既可以应用在正方形网格上,也可以应用在NavMesh等其他结构上。这得益于它的基 … Meer weergeven 路径规划是与机器人技术和视频游戏紧密相关的技术,它通常由两个核心问题构成: 1. 抽象图数据:将连续地形信息离散化为图数据 2. 路线生成:从一个给定的起始点,沿图数据的 … Meer weergeven 本文中,我们考虑以立方体单元组成的3D网格。所有立方体单元的顶点的集合记做 V。点Sstart表示寻路的起始点,它是某个立方体单元的某个顶点,即 Sstart∈V。点Sgoal表示 … Meer weergeven 原文在本节中定义了最短顶点路径,实际也可理解为就是基于LOS的最短路径,它是与最短边缘路径相对的,最短边缘路径即A * 找出的基于网格边的最短路径。由这三者得到如下关系: 最短边缘路径 ≥ 最短顶点路径 ≥ 最短实际 … Meer weergeven A * 伪代码如下: 图 2: 本文所有讨论都是基于上图 A * 伪代码,并以此为基础进行更改。 在A * 算法中,每个顶点持有两个重要的数据: 1.
