Abstract

The invention provides a three-dimensional observation system surface element attribute multi-thread rapid display method, belonging to the seismic prospection and exploitation field. The method performs partitioning pretreatment on a three-dimensional observation system surface element attribute analysis result, and utilizes a multi-thread mode to increase covering frequency data reading and display drafting efficiency. The method comprises: (1) establishing a three-dimensional observation system covering frequency attribute matrix structure; (2) dividing the covering frequency attribute matrix structure into N sections in a surface element grid x-line direction; (3) obtaining the size of a current window drafting area, and creating N pieces of QPixmap pictures, wherein each picture corresponds to 1/N of the covering frequency attribute matrix structure; (4) creating N threads, respectively loading a covering frequency, and drafting the covering frequency into a corresponding QPixmap picture; and (5) drafting the N pieces of QPixmap pictures on corresponding positions of a screen. The method innovatively realizes three-dimensional observation system surface element attribute pretreatment.

Description

technical field [0001] The invention belongs to the field of seismic exploration and development, and in particular relates to a multi-thread fast display method for panel attributes of a three-dimensional observation system. Background technique [0002] With the gradual development of 3D seismic exploration technology, more and more high-precision and high-density observation systems are designed in recent years, which makes the data volume of the panel attribute analysis results of the 3D observation system very large. Usually we want to be able to quickly see the coverage frequency distribution map of the entire work area on the screen, but when the data volume of panel attribute analysis is relatively large, the drawing of the coverage frequency distribution map will occupy a large amount of system resources, making the display efficiency very slow. [0003] The traditional programming idea is serialization, which is only suitable for running on a single-core processor....
