摘要：【中文】本发明公开了一种基于卷积的气象传真图等值线交叉点检测方法，首先对气象传真图进行预处理，得到仅含细化等值线的图像；然后将细化的等值线与卷积核进行卷积运算，通过设定阈值以及判断图像的八邻接节点个数得到分类的候选交叉点，再通过计算候选点与每类中心点的最小欧式距离得到最终的交叉点；对于交叉点的迁移以及畸变，通过等值线宽度和最大角度的判定方法进行合并，最终将检测出的交叉点在等值线上进行标记。本发明采用基于卷积的等值线交叉点检测方法，能够在复杂的等值线中保持较高的检测精度，具有计算量小、检测效率高等特点。 【EN】The invention discloses a method for detecting a meteorological facsimile diagram contour intersection point based on convolution, which comprises the following steps of firstly preprocessing a meteorological facsimile diagram to obtain an image only containing a refined contour line; performing convolution operation on the refined contour line and a convolution kernel, obtaining classified candidate cross points by setting a threshold and judging the number of eight adjacent nodes of the image, and obtaining a final cross point by calculating the minimum Euclidean distance between the candidate point and the central point of each class; and for the migration and distortion of the intersection point, merging the transition and distortion by a contour line width and maximum angle judgment method, and finally marking the detected intersection point on the contour line. The method for detecting the intersection point of the contour line based on the convolution can keep higher detection precision in the complex contour line, and has the characteristics of small calculated amount, high detection efficiency and the like.
