The invention discloses a quantum ant colony algorithm-based unmanned surface vehicle navigation path planning method and belongs to the unmanned surface vehicle and navigation path planning technicalfield. According to the method of the invention, a quantum ant colony algorithm is adopted to solve the navigation path planning problem of an unmanned surface vehicle. The method includes the following steps that: the static environment model of a navigation area is established according to an obstacle distribution condition in a geographic information database; the navigation path planning comprehensive evaluation function of the unmanned surface vehicle is established according to the objective function and constraints of the navigation path planning of the unmanned surface vehicle; and the quantum ant colony algorithm is adopted to perform global static navigation path planning on the unmanned surface vehicle. The algorithm provided by the invention not only can reflect the high efficiency of quantum computing, but also maintain the good searching capacity and strong robustness of the ant colony algorithm, and therefore, the calculation speed of the algorithm can be can improved.With the method adopted, the optimal navigation path of the unmanned surface vehicle under a complex sea condition can be obtained effectively and quickly, and therefore, the optimal navigation path can be obtained under a premise that the unmanned surface vehicle satisfies the constraints, and thus, mission requirements can be satisfied.
