Geometric correction method and device of projection picture, storage medium and electronic equipment

The invention relates to a geometric correction method and device for a projection picture, a storage medium and electronic equipment, and the method comprises the steps: carrying out the meshing of the projection picture, and generating a mesh patch; a central control point is initially arranged on at least one vertex of the grid patch, and slope control points and density control points located on connecting lines of the central control point and the slope control points are initially arranged on the first grid line and/or the second grid line where the central control point is located respectively; in response to the movement of the density control points, controlling the grid density distribution in the corresponding direction according to the movement of the density control points, or in response to the movement of the slope control points, controlling the slope of the grid lines controlled by the slope control points according to the connecting lines between the slope control points and the central cont
