New Approach for Oil-Well Symbol Recognition in Petroleum Geological Structure Map

In respect to the recognization of oil-well identifier in scanned petroleum geologic structure map, a fuzzy classification & identification method based on matching template correction is presented. By analyzing the attributes of a target map and correcting the matching template, identification & classification is conducted through fuzzy membership algorithm. The experimental results showed that the method can effectively and reliably recognize the identifiers that have geometric distortion and partial overlap, and has provided a more effective method for automatic recognization of oil-well identifier in petroleum geologic structure map.
