RETRACTED ARTICLE: Prediction of coastal rainfall trend and development of coastal leisure sports based on remote sensing image processing

With the continuous development of society, people have entered a new era. People’s material needs have been basically met, and people are paying more and more attention to spiritual life and ecological health. After the problem of food and clothing was solved, people began to pursue leisure sports, which is a brand new direction of consumption. The coastal area has taken the lead in developing the exciting experience of leisure sports. The leisure environment in this area is very romantic and can also bring people a very exciting experience. In recent years, many people have gone to the coastal area to experience this kind of leisure sports, which has also promoted tourism. The economic development of the city in the coastal area has promoted the change of its development mode. We monitor rainfall in coastal areas, which plays an important role in the development of leisure sports. If we can predict the weather changes in advance, we can make timely countermeasures, make reasonable plans for sports time, and make reasonable arrangements for sports content. In this paper, the relationship between cloud cover changes and rainfall data is obtained by monitoring remote sensing cloud images, and a corresponding model is established. This paper also designs some cloud image parameters, uses the corresponding algorithm to explore the relationship between cloud image and rainfall, improves and optimizes the algorithm combined with matrix characteristics, and finally proposes a more efficient algorithm. After a series of experiments, it is proved that the algorithm proposed in this paper has higher timeliness and better accuracy. The research results of this project have been applied to the forecast of rainfall trends in coastal areas. At the same time, certain suggestions and strategies have been put forward for the development of leisure sports activities in coastal areas, which also laid the foundation for the development of subsequent leisure activities.
