MULTI-PROJECTION DISPLAY SYSTEM OF SOLAR REFLECTION LIGHT AND PROGRAM FOR ADJUSTING DIRECTION OF MOVABLE FLAT SURFACE MIRROR USED IN THE MULTI-PROJECTION DISPLAY SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a multi-projection display system using a plurality of solar reflection light by projecting solar reflection light of each of a plurality of movable mirrors to a part designated at every movable mirror beforehand.SOLUTION: A multi-projection display system includes: a direction calculation part 1a which determines a solar direction standard vector v2 for exhibiting a direction to the sun and a projection direction standard vector v1 for exhibiting a direction to a projection object part 10 at every movable flat surface mirrors 8a to 8d; a control signal preparation part 1b which determines direction adjusting data of each flat surface mirror for inclining the flat surface mirrors 8a to 8d to such a state that each solar reflection light is projected to the projection object part 10 based on the solar direction standard vector v2 and the projection direction standard vector v1; and biaxial control parts 9a to 9d which adjust the direction of each flat surface mirror at every elements of a solar light elevation angle and a solar light azimuth angle based on the adjusting data.SELECTED DRAWING: Figure 1
