“…In terms of algorithm innovation strategies, Hong et al [32] proposed an improved A * algorithm using a closed list with random access data structures, which improved the efficiency of path planning. In hierarchical search strategies, Felix et al [33] proposed using the idea of multi-resolution search for path planning, increasing the speed of planning, but the accuracy of the primary search path could not be guaranteed, leading to the inability to obtain the optimal solution. It is worth noting that most existing A * algorithms are mainly applicable to path planning tasks with small-scale data.…”

“…The set of all sensing planes generates a coverage tree and the authors propose a strategy to navigate it assuming no false positives in identifying the presence of a region of interest from each node. A similar multi-resolution coverage problem with a single UAV is presented in [11]. Also in this case, no prior information is taken into account and the UAV adapts at each step its altitude to obtain a suitable resolution to perform deep-learning based semantic segmentation of the terrain.…”

“…Since we are interested in minimizing the open path between the position of the UAV and one of the ends of a segment, we introduce the artificial node 2g + 1 that is connected to node 0 (UAV position) (10), and has equal distance from all other nodes. These distances are set to zero to not impact the path length (11). We find the minimum closed path on this problem and remove node 2g +1 from the solution.…”

“…The trial is performed on each cell only once to prevent added correlation effects at that altitude. The outcome of the single trial is added to the α and β values previously selected as the prior (shown in Figures 7 and 8) and then integrated numerically according to Equation (8). Figures 10 and 11 show the updating stage at different time instances and altitudes.…”
