Abstract: In order to meet the security requirements, this paper proposes a method to construct a risk assessment function from GVD heuristic path and guide the final planning path to converge to the heuristic path. Firstly, the risk assessment function is constructed based on the surrounding environment of the heuristic path. Secondly, the Theta* algorithm is improved by taking the path cost as one of the indicators for parent node selection. Finally, a non-uniform cost calculation method is proposed and combined with the improved Theta* algorithm to obtain a global path that can avoid dangerous areas with both efficiency and safety. In addition, a series of simulation experiments show that the proposed method successfully avoids dangerous areas, and the hazard factor can be adjusted according to the specific task requirements, so that the path safety can be significantly improved in exchange for a smaller increase in path length, and can effectively plan a global path that meets the task requirements in a practical environment.
