Abstract

The invention relates to a route planning method and system based on a genetic ant colony algorithm. The route planning method comprises the following steps: S1, converting a part of optimal solution obtained by a genetic algorithm into a pheromone initial value of an ant colony algorithm; and S2, performing route optimization after the ant colony algorithm, and then performing crossover operation on the paths satisfying the condition to obtain an optimal path. The route planning method and system overcome inevitable defects in the single ant colony algorithm, namely high blindness of the ant colony algorithm at the initial search phase, realize advantage complement of the ant colony and genetic algorithms, reduce the path search range and improve the search efficiency of the optimal path.

Description

technical field [0001] The invention relates to the technical field of robot intelligent algorithms, in particular to a path planning method based on a genetic ant colony algorithm. Background technique [0002] Mobile robots are an important field of intelligent control technology. In addition to being used in space exploration, ocean development, and atomic energy, they also have broad application prospects in factory automation, construction, mining, risk elimination, military, service, and agriculture. There are many methods of path planning, such as the steepest descent method, artificial potential field method, fuzzy reasoning method, etc. Using the steepest descent method converges slowly, is not efficient, and sometimes does not reach the optimal solution; using the artificial potential field method is convenient for real-time control, but lack of global information, there is a problem of local optimal value; the biggest advantage of using fuzzy inference method is t...
