Abstract: For the stratum information about geological sectional view, a novel anti-interference stratum segmentation algorithm was proposed. Firstly the method used the variation functions and the confidence degree to measure the re- gional orientation angles, then based on the direction flow fields snake model, segmentation method was designed for the sub-regions with inconsistent directions. Secondly the method based on the gradient information to calculate image structure and orientation was abandoned, but image direction obtained by radon transform was integrated into the Gabor filter, thereby different geologic layers were accuratly extracted and internal gaps in the same geological layer were re- paired. Finally experimental results verify the effectiveness of our proposed method which has a better texture segmen- tation results in the practical geological section map, and our method plays a role in promoting the oil exploration and geological environment three-dimensional reconstruction.
