Abstract

A projection system and a projection method are provided. The projection system includes a processing module, a projection module and a photographing module. The projection module projects a first projection image based on a projection scope. The photographing module captures a part of the first projection image based on a photographing scope, so as to obtain a first photographic image. The part of the first projection image includes a plurality of first positioning grid points. The processing module analyzes the first photographic image, so as to obtain a plurality of first grid point coordinates. The processing module calculates a plurality of preset grid point coordinates corresponding to a plurality of preset positioning grid points in the whole projection scope one by one according to the first grid point coordinates. The processing module determines a projection result in the projection scope according to the preset grid point coordinates.
