| 摘 要： | 根据地质图中的图形元素的特点 ,给出了具有地质属性的工程图矢量化方法 ,从而将地质勘探图纸信息转化为具有地质信息的矢量数据。分块细化方法提高了大幅图纸的细化处理速度 ;数据优化处理从整体上考虑了勘探图素间的相关性 ,减少了矢量化过程中人为造成的误差 ;图形元素的部分非几何属性的自动识别提高了矢量化的自动化程度。这些方法在地质勘探图的矢量化系统中得到实现 ,并已在油田实际工作中应用。

| Abstract: | The vectorization and processing method for geophysical exploration drawing was presented. This method can be used to convert the paper drawings into the vectorization data involving geophysical information. The subdividing method can speed up the fineness of image. The optimization processing for vectorization data can reduce the human errors in consideration of the relativity among the graphic elements. Automatic recognition of partial non-geometry attribution for drawing vectorization can be realized. According to the above methods, a system for vectorizing geophysical exploration drawing was developed and has been broadly used. |
