A method and system for inter-checking data at gunpoints

Abstract

The invention provides a shot detection point data mutual checking method and system. The method comprises the steps that a the shot point coordinate, the shot point elevation data, the detection point coordinate and the detection point elevation data are received; b according to the shot point coordinate and the shot point elevation data, a shot point near-surface elevation model is established to acquire shot point near-surface elevation data, and according to the detection point coordinate and the detection point elevation data, a detection point near-surface elevation model is established to acquire detection point near-surface elevation data; and c the shot point near-surface elevation data are compared with the detection point near-surface elevation data, and processing is carried out according to a comparison result. According to the technology provided by the invention, the labor cost can be greatly reduced; the work efficiency and effectiveness are improved; the whole process is programming and processized; the work efficiency can be greatly improved to lay a solid foundation for follow-up processing and correct data inputting.

Description

technical field [0001] The present invention relates to the technical field of geophysics, and more specifically, to a method and system for inter-checking data of artillery inspection points. Background technique [0002] As far as the acquisition and processing of 3D seismic data is concerned, it is very important to ensure the accuracy of the position and elevation data of the shot-check point. The accuracy of input raw seismic data and near-surface data is the basic requirement for continuous processing of single 3D seismic data and multi-block 3D seismic data. However, due to the tens of thousands of positions and elevation data of the artillery inspection points, the data volume is extremely huge, and the reference points of the collected data in different years may be different, and there may be more or less errors in the process of entering or sorting out the field collected data. The changes or errors of these reference points will have a serious impact on the calc...
