Abstract
A method and system for decomposing cross-domain path planning of an amphibious vehicle. The method includes: defining a starting point and a target point of cross-domain path planning by acquiring an amphibious map containing coastline information, constructing a candidate set of land-water transition points; setting a multilevel gradient search range on a coastline and a set number of iterations; determining a locally-optimal land-water transition point in each search range in a level-wise search mode; setting a heuristic search termination condition, and determining, based on the heuristic search termination condition, whether a current locally-optimal land-water transition point can be globally optimal; if yes, stopping searching, and determining a globally-optimal land-water transition point; if no, determining whether the range is completely traversed; if yes, stopping searching, and determining a globally-optimal land-water transition point; if no, continuing to traverse the range; finally performing global path planning based on the globally-optimal land-water transition point.
