VECTORIZATION OF GEOPHYSICAL EXPLORATION DRAWING

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.
