description The present application relates to the technical field of projection, and provides a projection correction method and apparatus, a device, and a storage medium. The method comprises: in a projection correction page after keystone correction, obtaining a first adjustment operation for a first vertex of a projection screen; in response to the first adjustment operation, obtaining vertex coordinates of a light engine image corresponding to the projection screen; determining, according to the vertex coordinates of the light engine image, an outer frame of a simulated imaging element corresponding to the light engine image, and coordinates of the outer frame of the simulated imaging element, the outer frame of the simulated imaging element being a rectangular frame; on the basis of a first distance, the coordinates of the outer frame of the simulated imaging element, and a screen correction function associated with a preset display scale, determining a new light engine image for correcting the projection screen; a
