Abstract
Method, system, and computer program product for tracing seismic sections to convert to digital format are provided. The method includes: receiving a scan of a seismic section having multiple overlapping traces measured at spot points; splitting the traces into segments; associating the segments with appropriate baselines; estimating the traces between segments using logical rules; and deriving amplitudes of the traces.
Claims27
A method for converting tracing paper data to digital format, comprising:
- providing said tracing paper having a plurality of oscillating traces with a plurality of overlap areas between said plurality of traces;
- scanning said tracing paper and converting said tracing paper to a binary digital image;
- identifying said plurality of overlap areas by processing said binary digital image;
- physically splitting said plurality of traces into a plurality of non-touching segments by processing said binary digital image;
- reconstructing said plurality of traces by independently processing said non-touching segments of said binary digital image to restore values of said plurality of traces in said plurality of overlap areas;
- and
- outputting data of each of said plurality of traces as a data structure.
A computer program product for converting tracing paper data to digital format, said computer program product comprising:
- a computer readable storage medium having computer readable program code embodied therewith, the computer readable program code comprising:
- computer readable program code configured to:
- scan said tracing paper having a plurality of oscillating traces with a plurality of overlap areas between said plurality of traces and convert said tracing paper to a binary digital image;
- identify said plurality of overlap areas by processing said binary digital image;
- physically split said plurality of traces into a plurality of non-touching segments by processing said binary digital image;
- reconstruct said plurality of traces by independently processing said non-touching segments of said binary digital image to restore values of said plurality of traces in said plurality of overlap areas;
- and
- output data of each of said plurality of traces as a data structure.
A system for converting tracing paper data to digital format, comprising:
- a processor;
- a receiving component for scanning said tracing paper having a plurality of oscillating traces with a plurality of overlap areas between said plurality of traces, converting said tracing paper to a binary digital image and identifying said plurality of overlap areas;
- an image processing mechanism for processing said binary digital image to:
- identifying said plurality of overlap areas;
- physically splitting said plurality of traces into a plurality of non-touching segments;
- and
- reconstructing said plurality of traces by independently processing said non-touching segments to restore values of said plurality of traces in said plurality of overlap areas;
- and
- a trace writing component for outputting data of each of said plurality of traces as a data structure.
