摘要进入21世纪，随着全球气温升高，气象事业逐渐得到人们的重视，气象业务需逐年增加。相对于气象图的单一模式，与数字图像处理相关的气象图在现实的应用中发挥着特别广泛的应用。本文主要对在气象领域的二文气象图的基础上对图像本身进行数学图像处理上的三文拟合，使得能够更好的显示现实气象图的本来面貌，以利于人们对气象图更直观的进一步了解。相应的研究成果如下：26951

⒈对在所给出的气象图进行相应的预处理，包括二值化、框提取、以及气象图中锋线的提取。在实际的处理中只是对相应的知识进行一般化的掌握和验证，没有进行更深一步的探究。
⒉对于已知的等值线进行方法上的探索，在文中给出了等值线差值的一般方法，并在此基础上提出了自己的方法。通过四边形寻找差值，得到新的等值线，经过处理得到矢量化的内差值等值线。
⒊该过程是本文的重要研究，在得到等值线内插值的基础上，对矢量化的等值图进行气象三文的拟合重建，主要运用了仿射正交二阶张量曲面和矫正四边形曲面对等压面进行三文拟合重建

Fitting of three-dimensional weather maps
In the 21st century, as global temperatures rise, the meteorological service gradually get people's attention, meteorological services need to increase year by year. With respect to a single mode of a weather map, and digital image processing-related weather maps play a particularly wide range of applications in the real application.
This paper focuses on the basis of a two-dimensional field of meteorology weather map of the three-dimensional image itself to fit on mathematical image processing, enabling better weather maps show the original appearance of reality in order to facilitate people more intuitive further weather map Learn. Relevant research results are as follows:
⒈ given to the weather map corresponding pretreatment, including binarization, frame extraction, and extracting in front of a weather map. In the actual process only grasp the corresponding knowledge and verification generalized, no deeper inquiry.
⒉ known for contour exploration methods, we give a general method contour differences in the text, and on this basis put forward their own way. Looking through the quadrilateral difference, get new contours, get treated within the difference vector of the contour.
⒊ The process is important this study, getting inside the contour interpolation, based on the vector of contour maps to fit a three-dimensional reconstruction of the weather, the main use of the second-order tensor affine orthogonal surfaces and correct quadrilateral Qu three-dimensional face isobaric surface fitting
Keywords：Pretreatment、weather maps, contour interpolation inside, 3D reconstruction, affine second-order tensor
