Abstract: A method for automatically generating and projecting multi-surface image which automatically recognizes a plurality of projection surfaces using an image projector and a camera and projects images separately, includes: projecting scan image for pixel determination on a scan area including the plurality of projection surfaces using the image projector; recognizing the plurality of projection surfaces using image of the scan area including the plurality of projection surfaces photographed by the camera; matching the projection surfaces recognized by the image photographed by the camera while the scan image is projected and corresponding pixels of a display screen of the image projector; and projecting image which fills the pixel area of the display screen of the image projector corresponding to the areas of the projection surfaces.
