Research on aquaculture is an important part of environmental science. Aiming at the problem of aquaculture safety monitoring, this paper proposes a detection and judgment method for theft based on multi-source information fusion. The iterative Bayesian inference is used to integrate multi-source information such as abnormal human posture recognition, abnormal sound recognition and occurrence time to obtain relevant data on whether the aquaculture farm has been stolen. The experimental results show that, compared with traditional methods such as video detection or audio detection, the algorithm in this paper can determine whether the aquaculture farm is in a safe, suspicious or stolen state more quickly and accurately, thus providing an accurate disposal basis for managers. At the same time, the algorithm has better robustness.

Aiming at the problems of low coverage rate and high path repetition rate for unmanned surface vessels to complete full coverage tasks in irregular areas, the use of remote control navigation puts forward higher requirements for real-time and maneuverability. Therefore, a full coverage path planning system for the USV is designed. The system uses the concave points to segment the irregular task area, and then performs the area reciprocation algorithm for each convex sub-polygon. Finally, the sub-areas are connected based on the improved algorithm of dynamic programming, and the full coverage path planning of the USV is realized. Combined with the actual electronic chart to carry out the full coverage experiment, the coverage rate is high and the repetition rate is low, which can be actually used for the USV full coverage navigation tasks.

To solve the problems of difficult selection of position samples and high manual dependence of position recognition in most existing researches, this paper proposes a position extraction method combining visual saliency and line segment intensity. In order to verify the effectiveness of the algorithm proposed in this study, the two images were tested, and evaluated the accuracy through quantitative indicators. It can be found that the IoU (Intersection of Union) of the two positions are 0.6658 and 0.5319, respectively, which are all greater than 0.5, indicating the effectiveness of the unsupervised extraction method proposed in this research. The recall rate of the position was all greater than 0.83, indicating that the omission rate of the extracted positions by this method was relatively low, all within 17%. In this study, an unsupervised position extraction method is proposed, which can effectively extract target without training samples, and provides a reliable technical means for rapid unsupervised target recognition.

Based on the practical work, this paper discusses the current visualization techniques of geospatial data. Based on the traditional method of publishing geospatial data service by GIS server, when the data service has been published, it is not convenient to change the layer organization structure of the current data service. When the layer combination structure of geospatial data service needs to be changed, it can only re-publish the new data service. When a large number of data services are published, the server occupies a large amount of memory resources and deteriorates the server performance. This paper proposes a visualization method of geospatial data based on GIS and reverse proxy. When the data service has been published, it can flexibly conFigure the layer structure of the data service according to the actual work needs. By means of computer reverse proxy technology, the security of geospatial data sharing is improved, and the problem of GIS server performance degradation caused by re-release of data service is avoided.

Aiming at the characteristics of complex noise sources in multi-beam bathymetric data, this paper proposes a multi-beam automatic filtering method that combines filtering of optimal reference curved surface and trend surface. By implementing statistical filtering to pre-process the data, the optimal reference curved surface is constructed based on the filtered terrain data, the theoretical optimal depth value of each beam point is calculated. The optimal reference curved surface is filtered by combining the depth tolerance to determine whether the point is a noise point. Then the trend surface is constructed using the filtered non-noise data, and the trend surface is filtered on the original point cloud data. Through the verification of the measured data, this method can effectively remove most of the cluster noises in the multi-beam bathymetric data and is more efficient than manual processing.

At this stage, in the inversion research of shallow sea geoacoustic parameters, the traditional inversion method focuses on calculating the parameter inversion under the default seafloor layering, and does not clarify the seafloor layering. Therefore, when dealing with the experimental data under the unknown seabed stratification, the geoacoustic parameters that conform to the specific seabed stratification cannot be accurately given. Aiming at such problems, this paper proposes a layered shallow sea geoacoustic parameters inversion method based on a layered physical model of the seafloor and a neural network algorithm model. First, a subsea physical model with a layered structure is selected through simulation, and the fast field sound field method (FFM) is used to calculate the sound field, then the theoretical prediction value of the shallow sea acoustic pressure field under different layered conditions is obtained. Second, the pattern recognition neural network algorithm is established to analyze the characteristics of the predicted sound pressure field under different seabed layers. Finally, according to the layered results, the sound pressure field is substituted into the seabed parameters inversion model of the corresponding layers, and the seabed parameters inversion is performed to obtain the inversion results. Experiments results show that the number of model iterations in the neural network algorithm is less and the efficiency is higher. The problem of seabed stratification is effectively solved through the characteristic analysis of the sound pressure field, which greatly improves the convenience of the inversion work.
