Abstract

The invention discloses a multi-UAV/UGV collaborative long-term operation path planning method based on multi-objective optimization. The method comprises the following steps: converting a multi-taskfixed charging point problem into a traveling salesman problem for solving through a construction method of a graph of a multi-task fixed charging point problem; according to the construction method of the graph of a multi-task discrete charging point problem, converting the multi-task discrete charging point problem into an equivalent generalized traveling salesman problem to be solved by utilizing a graph conversion algorithm; using a heuristic algorithm ALFG for directly solving the generalized traveling salesman problem; and solving the UAV/UGVs long-term multi-target path planning problemby using a solving algorithm MOALP. According to the multi-UAV/UGV collaborative long-time operation path planning method based on multi-objective optimization, the operation efficiency, the operation duration and the operation range of a ground-air collaborative robot can be effectively improved, more operation task requirements are met, and the higher autonomy effect is achieved.
