(eds.), Advances in Water Resources and Exploration. Journal of Coastal Research, Special Issue No. 93, pp. 941–946. Coconut Creek (Florida), ISSN 0749-0208.In order to evaluate the sealing performance of nano-scale magnetic thin film materials in marine tanks, a method for evaluating the sealing performance of nano-scale magnetic thin film materials in marine tanks based on spatial visual image feature extraction is proposed. The differential frame point scanning and spatial vision high resolution imaging analysis method are used to collect the image information of ship tank nano-scale magnetic thin film material. The sealing gap of ship tank nano-scale magnetic film material, the weakening of material mechanics, the sealing frame point and other parts of the three-dimensional frame structure reconstitute image modeling. The edge structure feature decomposition and texture segmentation of ship tank nanoscale magnetic film material images are carried out. The stress fitting model of structural seal gap of ship tank nano-scale magnetic film material is constructed. The feature point extraction and mechanical state dynamic estimation of ship tank nano-scale magnetic film material seal gap are carried out by using three-dimensional frame structure reconstruction image feature extraction method, and the accurate prediction and evaluation of seal gap state of ship tank nano-scale magnetic film material seal are realized. The simulation results show that the sealing performance of nano-scale magnetic thin film material in ship tank is tested by this method, and the positioning accuracy of sealing gap point of nano-scale magnetic thin film material in ship tank is higher, the reliability index of closed performance evaluation is better, and the failure probability is the smallest.
