Holographic laser projection stage system and control method thereof

The invention relates to the field of holographic laser projection, in particular to a holographic laser projection stage system and a control method thereof. In the adopted technical scheme, the holographic laser projection stage system comprises a stage, a background screen, an upper movable screen, a middle movable screen and a lower movable screen, wherein the upper movable screen, the middlemovable screen and the lower movable screen are arranged in front of the background screen. By arranging a movable rail frame above the stage, the upper movable screen, the middle movable screen and the lower movable screen can move along the movable rail frame and are matched with the background screen, so that a better and more flexible three-dimensional effect is realized; meanwhile, a master control computer is connected with sub-control computers, the sub-control computers are connected with different projection screens for control, and therefore control over the whole stage system is realized.
