Abstract

The invention discloses a parallel calculation method and system for cannon attribute fusion. The method comprises the following steps that: a main thread reads cannon data and obtains the signal-to-noise ratio, the energy and the resolution of the cannon; on the basis of the signal-to-noise ratio, the energy and the resolution of the cannon, through a first calculation thread group, simultaneously carrying out calculation to obtain the signal-to-noise ratio mean square root, the energy mean square root and the resolution mean square root of the cannon; on the basis of the signal-to-noise ratio mean square root, the energy mean square root and the resolution mean square root of the cannon, carrying out roller shutter type distribution on multiple threads of a second calculation thread group, and meanwhile, carrying out fusion calculation to obtain a fusion result; on the basis of the fusion result, carrying out roller shutter type distribution on the multiple threads of a third calculation thread group, and meanwhile, carrying out interpolation calculation to obtain interpolated grid data; and on the basis of the interpolated grid data, carrying out the roller shutter type distribution on multiple threads of a fourth calculation thread group, and meanwhile, rotating a coordinate to obtain the position of the grid data. By use of the method, through the parallel calculation of the cannon attribute fusion, wide-orientation high-accuracy real-time quality evaluation collection is realized.

Description

technical field [0001] The present invention relates to the field of oil and gas exploration, and more specifically, to a parallel calculation method and system for gun attribute fusion. Background technique [0002] With the rapid development of the field of oil and gas exploration, the geological conditions of the exploration target area are becoming more and more complex, and the acquired shot data is also becoming more and more complex. The requirements for the fusion calculation method of shot attributes are also increasing. At present, the existing technology adopts serial processing, which cannot achieve the purpose of real-time evaluation in wide-range and high-precision acquisition. Therefore, it is necessary to develop a parallel computing method and system for gun attribute fusion. [0003] The information disclosed in the background of the present invention is only intended to deepen the understanding of the general background of the present invention, and shoul...
