Abstract: Guiding path planning, as an important part of the garden intelligent assistant guiding system, can provide visitors with real?time destination map path guidance, which directly affects the user experience. In order to improve its accuracy and real?time performance, a garden guiding path planning method based on artificial fish swarm is proposed. The guiding environmental model and related problems are described, and the objective function of path planning is designed by total length and smoothness. In addition, the artificial fish swarm algorithm is analyzed. In consideration of the shortcomings of the artificial fish swarm algorithm, the step size update method is improved, which is beneficial to the improvement of the optimizing precision and running speed. The test results in the simulation environment show that the improved algorithm has better optimal solution and fast convergence performance. The actual application results verify the feasibility and effectiveness of the proposed path planning method.

Keywords: garden guiding; path planning; artificial fish swarm algorithm; adaptive step size; objective function; iterative curve
