WebFeb 15, 2024 · Path planning and obstacle avoidance are essential for autonomous driving cars. On the base of a self-constructed smart obstacle avoidance car, which used a LeTMC-520 depth camera and Jetson controller, this paper established a map of an unknown indoor environment based on depth information via SLAM technology. The Dijkstra algorithm is … WebJun 9, 2024 · The Dijkstra algorithm is a milestone in the analysis of the SPP with crisp information. When arc lengths are crisp numbers, it can be easily understood and applied. However, in networks of ambiguous nature, the optimization methods designed for crisp lengths may not be immediately employed when data are fuzzy numbers.
