Problems solved by technology

In order to obtain as much underground information as possible with less workload, the layout of the profile lines is often perpendicular to the formation trend. In actual field exploration, the point stakeout azimuth and the line stakeout azimuth are often in an orthogonal relationship, and the azimuths differ by 9

Abstract

The invention relates to the field of geophysical exploration, and discloses a field point lofting method for geophysical exploration, which is characterized in that a lofting reference point is determined in a lofting area, and then field point lofting is carried out through a recursion method. According to the method, any lofting angle can be selected for the point orientation and the line orientation of field geophysical exploration; the situation that single-line lofting is easily interfered by factors such as field rivers, lakes and villages is avoided, and multi-line lofting in the area can be carried out at the same time; according to the method, a related operation interface can be developed based on a Matlab language, man-machine interaction can be realized, and lofting parameters can be changed according to requirements.

Description

technical field [0001] The present application relates to the field of geophysical prospecting, in particular to a method for setting out points in the field of geophysical prospecting. Background technique [0002] In regional geological survey and resource exploration, geophysical exploration methods are conventional application methods, such as gravity exploration, magnetic exploration, electrical exploration and so on. The stakeout in exploration work mainly includes the following information: point stakeout orientation, line stakeout orientation, point distance, line distance, point number increment, line number increment and other related information. The rapid positioning of dotted line numbers in field geophysical exploration is an important part of project design and establishment. It is a necessary work based on the relevant design requirements of the project on the basis of collecting relevant geological data and surveying. In the actual geophysical exploration w...
