摘要

In this research, in order to improve edge identification quality of seismic profile strata and improve the edge identification speed of seismic profile strata, high-speed and high-precision adaptive Sobel algorithm based on ZYNQ is proposed. The implementation of high-speed and high-precision adaptive Sobel algorithm is based on fast median filtering algorithm, Coordinate Rotation Digital Computer (CORDIC) algorithm, adaptive threshold algorithm and hardware acceleration technology. The experimental results show that the adaptive Sobel algorithm proposed in this study can better identify the edge details of seismic section strata. Compared with the traditional high-precision adaptive Sobel algorithm, the speed of Sobel algorithm proposed in this research is increased by 115.74. Hence, the algorithm proposed in this paper is an adaptive Sobel algorithm with high speed and high precision, which is suitable for the edge identification of seismic section stratigraphic map.
