In automatic navigation of mobile systems, first, they require providing a path network for robot/vehicle motion. Therefore, path planning is an important task of autonomous vehicle systems. To deal with the problem, this paper presents a method for constructing the shortest path, which support for vehicle auto-navigation in outdoor environments. The method using online road map images to estimate...
This paper considers the Euclidean shortest path problem among obstacles in ℝn. Adaptations of Dijkstra's and A* algorithms are introduced that compute the approximate cost-to-go function over a simplicial complex embedded in the free space. Interpolation methods are carefully designed and analyzed so that they are proven to converge numerically to the optimal cost-to-go function. As the result, the...
