Safety and efficiency of carrier flight deck are two important factors that have great effects on the comprehensive performance of carrier. This paper studies on path planning algorithms for carrier aircraft on the deck in consideration of safety and efficiency requirements. Firstly, a kinematic model of the carrier aircraft, obstacle avoidance models and boundary constraints are proposed. Subsequently,...
This paper proposes a new algorithm for solving the robot path planning problem which includes finding a path from a source to a destination subject to certain constraints. First, using the overhead view of the surroundings, a free space model is created using MAKLINK graph theory. Then Dijkstra's Algorithm is applied over the MAKLINK graph to obtain a sub-optimal path. This sub-optimal path is further...
The path planning is a very important part of AGV control. Firstly, The OpenCV is called to fitting the contour of obstacles with polygon and to optimize the result. Then a model of AGV work space is built by the method of network topology. So the problem of AGV path planning can be transformed into the problem of searching for the shortest path of the network topology. In the process of searching,...
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...
Path-planning problems are fundamental in many applications, such as transportation, artificial intelligence, control of autonomous vehicles, and many more. In this paper, we consider the deterministic path-planning problem, equivalently, the single-pair shortest path problem on a given grid-like graph structure. Current commonly used algorithms in this area include the algorithm, Dijkstra's...
The path length and number of turns are the major factors in path planning of transportation and navigation systems. Shortest path planning has been widely studied in the literatures. Most researches only take the issue of shortest distance into account, and the impact of turns are rarely mentioned, that is, the shortest path may not be the fastest. Considering both two factors in a path-searching...
