| 摘 要： | 本文介绍一种最大梯度追踪和旋转变换方法，可用于重磁数字图像特征线自动提取。该方法分两步进行，首先用最大梯度追踪法产生二态像素图，然后用旋转变换方法将二态像素图的栅格特征线转换成矢量特征线。此方法生成的文件可以与ＧＩＳ接口。

| Abstract: | A maximum gradient tracing and rotation transformation approach is presented in this paper. It is used for extracting linear feature from magnetic and gravity data. This algorithm includes two steps. First, a binary linear image is generated using the maximum gradient tracing algorithm. Second, the rotation transformtion is used to extract the linear feature from binary image. The images formed by this approach are linked with GIS. |
