Projection control equipment for double-projection three-dimensional stereoscopic imaging digital sand table and method of projection control equipment

Abstract

The invention discloses projection control equipment for a double-projection three-dimensional stereoscopic imaging digital sand table and a method of the projection control equipment. The equipment comprises a box body and three laminated plates which are mounted in the box body from bottom to top; the box body is partitioned through the three laminated plates so as to form four layers of accommodating cavity bodies from bottom to top; a control chassis is mounted in the first accommodating cavity body; a lower fan for sucking the air is mounted at the bottom ends of the accommodating cavitybodies; a first laser projector is mounted in the second accommodating cavity body; a plain master plan sand table is mounted on the left side of the inner part of the third accommodating cavity body;holographic illusion imaging glass is mounted on the right side of the inner part of the third accommodating cavity body; an upper fan for exhausting hot air and a second laser projector are mountedin the fourth accommodating cavity body; a projection plane of the first laser projector is positioned on the plain master plan sand table and first visual presentation is formed; a projection plane of the second laser projector is positioned on the holographic illusion imaging glass and second visual presentation is formed.

Description

technical field [0001] The invention relates to the technical field of sand table models, in particular to a projection control device and method for a double-projection three-dimensional imaging digital sand table. Background technique [0002] At present, in the model sand table, the application of multimedia projectors on the sand table mainly includes A front projection and B rear projection. Among them, A front projection is mainly used in multimedia model display, except for ordinary projection walls and screens. For video promotion, it can also be used as the projection object surface on the model sand table to achieve the display effect of projecting dynamic cars and boats on model roads and water. In addition, you can cast a display frame, that is, to highlight a certain area on the model in the form of a flowing frame selection, etc. The disadvantage is that the shadows of many buildings and other objects are obvious, and it is difficult to hide the projector, whi...

Problems solved by technology

One is to add a water atomization mechanism. After the projector is turned on with the water mist sprayed into a screen shape, a hazy virtual voice interactive robot appears; the other is a real screen as a projection surface. It stands between the audience and the projector, but apart from being able to hide the projector and present a large display surface, it is nothing special like a TV
