Due to the existence of multiple constraints and optimization objectives, the path planning of ocean survey is very difficult. In this paper, ant colony algorithm is applied to the path planning of ocean survey. Considering the coverage of ant colony algorithm, the path planning of ocean survey is carried out, the competitive decision of ocean boundary is made, and the initial solution is created. In the path planning of ocean survey, the local search scope is limited to the K-nearest neighborhood of the network, only the most possible spatial neighborhood is searched, and the quality of the solution is improved iteratively. The performance of the algorithm is tested by using ocean survey path planning. The experimental results show that the proposed method can solve the competitive decision-making problem of 6 400 survey paths in 15 minutes. The quality of the solution is 10.8% better than that of ArcGIS, and the computing time is about 21.2%.
