Abstract

The invention provides a geological target recognition method based on human face recognition, which is used to identify geological targets such as cracks and holes with different sizes and shapes. The specific method is as follows: load electrical imaging logging data, perform electrical imaging logging data preprocessing and processing, and generate dynamic and static images, etc.; load core data containing fractures or holes, and construct feature faces from standard geological targets; Extraction; feature extraction of test sample images; distance function selection; geological target pattern matching based on eigenface face recognition. Since the method first generates dynamic micro-resistivity images, and then uses face recognition technology to identify geological targets of different sizes and shapes, it has the characteristics of high precision and strong reliability, and can improve the recognition rate of geological targets.

Description

Technical field [0001] The present invention relates to a geological objective identification method based on face recognition, belonging to the field of logging technology data processing. Background technique [0002] Geological objectives identify the target recognition of cracks, holes, mainly relying primarily on manual identification, due to large workload, fracture, hole form, large change, relying on conventional logo identification cracks, holes and other geological objectives. Due to the image characteristics of the micro-resistance imaging log data, it is possible to identify a rock phase having different rock resistance, structural and construction, and can have different structural and structural structures, with different mineral particles and mineral type combinations. The arrangement is observed and identified, and higher resolutions and more accurate, more intuitive representations are obtained, so that the electrical imaging logging image has been widely used in...
