交互式等值线图纸矢量化方法

An Interactive Isoline map Vectorization Method

等值线图纸矢量化在地质、地球物理、地理信息系统等方面有广泛的应用,计算机自动识别在实际应用中尚存在一些不足,论文通过改进基于圆跟踪的等值线矢量化算法,提出了一种交互式的等值线的矢量化方法——等值线间隔追踪算法,通过人工干预弥补计算机自动识别存在的缺陷,保证追踪的正确性,适用于灰度等值线图像的矢量化,具有实用性和高效性。

Isoline map vectorization has been widely used in geology, geophysics, geographical information systems, etc. There are still some shortcomings of the computer automatic recognition in practical application. This paper presents an interactive isoline map vectorization algorithm by improving the isoline map vectorization algorithm based on the circular track. The isoline intervals tracking algorithm makes up for the shortcomings of computer automatic recognition by manual intervention, ensures the correctness of the tracking, fits for the grayscale isoline image vectorization. This algorithm is practical and efficient.
