Abstract

The embodiment of the invention provides an airborne gravity measurement quality evaluation method and device, equipment and a storage medium. The method comprises the steps that the airborne gravityabnormal value of each cutting line within the measuring area is measured; the airborne gravity abnormal value of the current measuring line within the current sortie is measured; the airborne gravityabnormal unconformity value of the intersection points of the current measuring line within the current sortie and each cutting line is calculated so as to calculate the original measurement accuracyvalue of the current measuring line within the current sortie; horizontal deviation correction is performed on the airborne gravity abnormal value of each cutting line, and the corrected airborne gravity abnormal unconformity value of the intersection points of the current measuring line within the current sortie and each cutting line is calculated according to the corrected airborne gravity abnormal value of each cutting line and the airborne gravity abnormal value of the current measuring line within the current sortie; then the corrected measurement accuracy value of the current measuringline within the current sortie is calculated; and the measurement quality of the current measuring line within the current sortie is evaluated according to the original measurement accuracy value andthe corrected measurement accuracy value.

Description

technical field [0001] The invention relates to the technical field of gravity measurement, in particular to a quality evaluation method, device, equipment and storage medium for airborne gravity measurement. Background technique [0002] Airborne gravimetry is one of the aerial geophysical exploration methods. Its process is to use small fixed-wing aircraft, helicopters or other flying platforms to carry airborne gravimeter (airborne gravimeter) system and GPS navigation and positioning system to measure the earth's gravity field ( The earth's gravitational field is a kind of gravitational action or gravitational effect that exists at any point in the space around the earth, or the gravitational force on the earth's surface or a nearby point, which is equal to the acceleration of gravity in value. The gravitational field is a force or force in space The force field is distributed on the surface of the earth and its adjacent space; any particle in the space is affected by gr...
