Abstract

This invention belongs to the field of seismic image rendering technology, and discloses an image rendering method and device based on raw seismic acquisition data. The image rendering method based on raw seismic acquisition data includes: determining the block level of the raw seismic acquisition data according to customer requirements and the maximum value of the number of horizontal and vertical sample points in the raw seismic acquisition data; dividing the raw seismic acquisition data into blocks according to the block level based on a quadtree algorithm, and assigning a sequence number to each block; indexing multiple blocks of data according to customer requirements and the sequence numbers of the block data to render the image. This invention improves the efficiency of data cropping involved in subsequent rendering and cross-referencing operations by performing block processing on the already loaded data in memory before image display, and improves rendering efficiency by using multi-threaded parallel rendering. This invention can conveniently realize the rapid organization, cropping, and parallel rendering of image data.
