Abstract

The utility model relates to the digital sand table field and discloses a three-dimensional virtual digital sand table projection system, which comprises a physical sand table (1). The projection system further comprises a projection device (2) and a projection screen (4). The projection device (2) is arranged between the physical sand table (1) and the projection screen (4). By arranging the projection device to project a three-dimensional virtual sand table on the screen, the projection system enables visitors to have more stereoscopic and direct-viewing display effects through the virtual sand table on the screen while visitors are observing the physical sand table.

Description

Three-dimensional digital sand table optical projection system

Technical field

The utility model relates to digital sand table, has related in particular to a kind of three-dimensional digital sand table optical projection system.

Background technology

At present, existing sand table can only be for the visitor to the planning of the layout in city, site of road, and the position of building etc. shows, the visitor can't carry out more deep understanding to planning and view.

Summary of the invention

The utility model shows that for outdoor scene sand table of the prior art content is limited, more space size and orientation details can only be sketched the contours by oneself the shortcomings such as the imagination, providing a kind of merges three-dimensional digital sand table and existing entity sand table, by optical projection system, the three-dimensional digital sand table is illustrated on screen, has three-dimensional digital sand table optical projection system more three-dimensional, bandwagon effect intuitively.

In order to solve the problems of the technologies described above, the utility model is solved by following technical proposals:

Three-dimensional digital sand table optical projection system comprises sand table, also comprises projector equipment and projection screen, and projector equipment is arranged between sand table and projection screen.

As preferably, also comprise switch board, switch board is connected with projector equipment by data line.

As preferably, described projector equipment is projector.

As preferably, described projector equipment is arranged on sand table.Projector equipment is arranged on the front end of sand table, when having avoided sand table is arranged on the sand table rear end, because the model on sand table has stopped projector equipment.

The utility model is owing to having adopted above technical scheme, have significant technique effect: the utility model is by arranging projector equipment, the three-dimensional sand table is projected on screen, the visitor is when observing the entity sand table, can be by the virtual sand table on screen, obtain more three-dimensional, bandwagon effect intuitively.

Description of drawings

Fig. 1 is the structural representation of the utility model embodiment 1.

The toponym that in above accompanying drawing, each number designation refers to is as follows: wherein 1-sand table, 2-projector equipment, 3-switch board, 4-projection screen.

Embodiment

The utility model is described in further detail with embodiment below in conjunction with accompanying drawing 1:

Embodiment 1

Three-dimensional digital sand table optical projection system as shown in Figure 1, comprises sand table 1, also comprises projector equipment 2 and projection screen 4, and projector equipment 2 is arranged between sand table 1 and projection screen 4.

Also comprise switch board 3, switch board 3 is connected with projector equipment 2 by data line.The image of virtual sand table is transferred to projector equipment by switch board, is rendering to projection screen by projector equipment, makes the user when observing the entity sand table, can understand in depth details by the 3-dimensional digital sand table on screen.The show staff is by browsing with any adjustment height, angle in three-dimensional environment; Displaying to planning, view has more solid and demonstrates intuitively effect, has true, three-dimensional, quick, easy, accurate, dynamic characteristics, to obtain the demonstration effect of more enriching.

Projector equipment 2 is projector.Projector equipment 2 is arranged on sand table 1.Projector equipment 2 is arranged on the front end of sand table 1, when having avoided sand table 1 is arranged on the sand table rear end, because the model on sand table has stopped projector equipment 2.

In a word, the above is only preferred embodiment of the present utility model, and all equalizations of doing according to the utility model claim change and modify, and all should belong to the covering scope of the utility model patent.
