Finally, an improved trajectory planning method based on Lazy Theta* which is an algorithm of any-angle-path planning is proposed and adjusted to different planning conditions. Web7 jun. 2016 · Lazy Theta* Rather then doing the line of sight check for each neighbors of the current node we assume that there is a line of sight and check it latter. So for each neighbors, we directly check if it would have a smaller g-value if we set the its parent to the parent of the current node and if it does then set it.

Web24 mrt. 2024 · Aerial robots are a promising platform to perform autonomous inspection of infrastructures. For this application, the world is a large and unknown space, requiring light data structures to store its representation while performing autonomous exploration and path planning for obstacle avoidance.
