Detailed description of the invention
Embodiment:
Fig. 1～Fig. 3 shows that of this digital sand table with landform teaching demonstration function of this utility model is concrete
Embodiment, it mainly includes topographic sand table 1, height detecting device 2, optical projection system 3, processor 4.Wherein:
Topographic sand table 1, for artificially generated terrain, can carry out map function to it, artificially to simulate different landform situations.
Height detecting device 2 is located at above described topographic sand table 1, and it is used for detecting described topographic sand table 1 upper surface everywhere
Height value, and will detect height value output.This height detecting device 2 typically uses photoelectric sensor, utilizes it to send
Light sense topographic sand table 1 upper surface everywhere to the distance of test point, obtain topographic sand table 1 upper surface height everywhere
Value.
Optical projection system 3 is located at the top of described topographic sand table 1, and it is for projecting described topographic sand table 1 upper surface
Operation.This optical projection system 3 can be simultaneously to the light of diverse location projection different colours.
Processor 4 is connected with described height detecting device 2 and optical projection system 3 respectively, and it is used for receiving height detecting device 2
The topographic sand table 1 upper surface height value everywhere of output, and according to the difference of topographic sand table upper surface height value everywhere, control described
Optical projection system 3 projects different color light everywhere to described topographic sand table 1 upper surface, so that the surface of topographic sand table 1 is pressed
Different colors is presented, to simulate the three-dimensional equal pitch contour of current landform according to the difference of " height above sea level ".This processor 4 is general
For computer.And, additionally it is possible to project animation light by described optical projection system 3 to topographic sand table 1, with natural wind simulating, sleet
Deng geographical scene, thus allow the person of receiving instruction obtain graceful multidate information true to nature vividly.
When instructor artificially changes the form of described topographic sand table 1, during so that the landform style and features of its simulation changes,
It is located at the height detecting device 2 above topographic sand table 1 and the change of topographic sand table 1 upper surface height value everywhere detected the most in time,
And the new height value everywhere detected in real time exports to processor 4.Processor 4 is according to topographic sand table 1 upper surface everywhere
The change of height value, control optical projection system 3 is to the light of topographic sand table 1 upper surface regional transmitting corresponding color, thus mould
Draw up the three-dimensional equal pitch contour of landform after change.As long as it is to say, the form of topographic sand table 1 changes, and making it simulate
When landform style and features changes, the color light that optical projection system 3 is launched to topographic sand table 1 upper surface regional is the most accordingly
Change, to simulate the three-dimensional equal pitch contour distribution of various landform real-time and accurately.
This example is also provided with the display 5 being connected with described processor 4, thus is demonstrated out according to current topographic sand table 1
Landform style and features, show the corresponding picture and text content of courses, to show the detailed geography information in now topographic sand table, such as when
The climatic characteristic of front landform, two dimension equal pitch contour distribution etc..
For the ease of instructor's operation to this digital sand table, this example is provided with the control being connected with described processor 4 eventually
End 6, this control terminal 6 for sending control instruction to described processor 4, with control described optical projection system 3 project content and
The display content of described display 5.Such as, instructor can control 3 throw lights of optical projection system by this control terminal 6
Power and the form of animation light, it is also possible to adjusted the geographic demonstration pattern of this digital sand table current by this control terminal 6,
Such as mountains and rivers pattern, ocean model, glacier pattern etc., and then make optical projection system 3 according to different geographical demo modes projection differences
The light of classification.
Under normal circumstances, this control terminal 6 uses mobile phone or panel computer (PAD), and it passes through wireless with described processor 4
Network connects, so that instructor can be remotely controlled operation to this digital sand table.Control terminal 6 in Fig. 1 is PAD.
And, we can also do simulated flight on sand table surface, and record-setting flight height and data, and can generate
Flight path figure and similar remote sensing figure.And sand table projection and display display picture are interactive picture content.
For the ease of the installation of above-mentioned all parts, this example is provided with a pedestal 7, and above-mentioned topographic sand table 1, height are examined
Survey device 2, optical projection system 3, processor 4 and display 5 to be installed on this pedestal 7.
