Gravity vector measurement method and system, medium, equipment and terminal

The invention belongs to the technical field of gravity measurement, and discloses a gravity vector measurement method and system, a medium, equipment and a terminal.The gravity vector measurement method comprises the steps that gravity scalar data is subjected to two-dimensional decomposition in the direction of the rotation axis of the earth according to the reference selection principle, and the gravity scalar data is the synthetic quantity of the three-dimensional measurement result of a gravimeter; through two-dimensional decomposition, a part of components are projected from gravity to the rotation axis of the earth, and the remaining components are determined according to vector triangle decomposition. According to the gravity vector measurement method, gravity projection is carried out by taking the rotation axis direction as a reference, and the rotation axis direction is a physical quantity and has physical measurability. According to the method, the reference is unified, comparison and monitoring o
