Cooperative Pointillistic Projection of a Graphical Image on a Pre-Selected Remote Surface by Using a Multiplicity of Lasers

1) The method of projecting a planned graphical image upon a specific pre-selected remote target surface with multiple laser beams, separately controlled by multiple persons known as laser projectors, with each laser beam contributing only one spot of light to the graphical image;

• comprising the following steps.
• a. Creating a planned image, consisting of a photograph, drawing, or other scale representation of a landscape that includes easily identifiable invariant visual features of the said remote target surface, as viewed from the position of a typical member of the group of said laser projectors;
• along with the said planned graphical image superimposed upon the said representation of said invariant visual features.
• b. Making multiple transparent image copies of said planned image, of an appropriate size or sizes to approximately match the apparent size of the actual said target surface when the latter is viewed from the expected location(s) of the laser projectors, through sighting optics having designated ranges of magnification;
• each said transparent image copy containing a designating mark or marks specifying a particular spot-like picture element (spot-pixel) within the desired graphical image;
• and the multiple transparent image copies having sufficient numbers of different spot-pixel designations so as to permit the overall graphical image to be created from the aligned composition of all the designated spot-pixels.
• c. Distributing one of the said transparent image copies to each member of the said group of laser projectors who, at the chosen time of projection of the said planned image, are to be positioned in a cluster of locations limited only by the requirement of having viewing angles of the said target surface that differ from that of the said planned image by no more than 30 degrees of horizontal or vertical parallax angle.
• d. Directing the said laser projectors to align said sighting optics so that each laser projector's view of his/her said transparent image copy will be visually superimposed upon his/her view of the said target surface, thereby bringing each said laser projector's laser beam into accurate alignment with his/her individually-designated spot-pixel upon the said remote target surface, each said laser having previously been affixed to the corresponding sighting optic so as to align the output laser optical axis with the sighting optical axis of said sighting optic.
