Embodiment Construction
[0043]Embodiments of the present invention are described in detail below, examples of which are shown in the drawings, wherein the same or similar reference numerals designate the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the figures are exemplary and are intended to explain the present invention and should not be construed as limiting the present invention.
[0044] First of all, the technical solutions of the prior art and the defects in the technical solutions are described below.
[0045] 1) Heuristic traditional path planning method
[0046] The A* algorithm is a graph search method. The A* algorithm needs to be used in a discrete grid map. In the basic A* algorithm, follow the steps below for global path planning:
[0047] Step 1: Put the initial node into the open list
[0048] Step 2: If there is no node in the open list, path exploration fails. Otherwise proceed to the next...
